About Single Chamber Skim Pans

The single chamber dross skim pan provides a single open-top collection volume for dross skimmed from the molten aluminium surface during melting and refining. The structural base incorporates ventilation geometry — supporting the pan during handling and transfer while allowing air circulation to assist cooling after dross collection. The single chamber configuration is the standard choice for most casthouse skimming operations where dross fraction separation is not required.

Material

All SMI single chamber skim pans are manufactured from SMI’s proprietary material formulation — developed over 30 years of continuous supply to aluminium casthouses worldwide. The formulation delivers rapid cooling rate and thermal shock resistance — the two performance requirements that determine service life in high-cycle casthouse environments. Alternative material options are available for specific operating conditions on request.

→ SMI Dross Press Systems — SMI40, SMI60, SMI80

Material and Design

All SMI skim pans and sow molds are manufactured from a proprietary material formulation developed in-house over three decades of continuous supply to aluminium producers. The formulation is optimised for two specific performance requirements in aluminium casthouse service:

  • Rapid cooling rate — the material composition and wall geometry are engineered to achieve a fast cooling rate after dross or metal contact, reducing the oxidation window and improving the quality of the recovered dross or cast sow
  • Thermal shock resistance — repeated thermal cycling from ambient to molten aluminium contact temperatures and back is the primary cause of premature failure in casthouse consumables. SMI’s proprietary formulation is developed specifically to resist this mechanism, extending service life in demanding casthouse environments

Alternative material options are available for specific customer requirements or operating conditions — contact SMI to discuss material selection for your casthouse application.

Custom Design Capability

SMI’s engineering team provides custom skim pan, sow mold and press dross pan design for casthouses with non-standard requirements. The design process begins with the customer’s basic drawing or sketch — SMI develops the detail design, including wall geometry, base configuration, chamber layout and drain features where applicable, and provides a quotation for review before production commitment.

Custom design is available for:

  • Non-standard chamber dimensions or capacities
  • Modified base configurations for specific handling or transport equipment
  • Custom chamber layouts for specific dross fraction separation requirements
  • Press dross pan configurations matched to specific dross press models — including adaptation to third-party press frames

Spiral Bevel Gear

Spiral Bevel Gear
Spiral Bevel Gear

Spiral bevel gear is a common part of mechanical transmission, but also an indispensable part of mechanical equipment, relatively difficult and complex process manufacturing, so we use advanced alloy steel 18CrNiMo7-6, more robust and durable, so that its precision level reached DIN3965 5-10.

Spiral bevel gear as the most important part of the transmission device, its quality and performance has been a point of great concern to people, for the traditional spiral umbrella design, with large noise, low efficiency, short life and many other problems, often affect the normal use of mechanical equipment. In view of this situation, the materials used and the design process of the gear have been greatly improved. Our spiral bevel gear adopts high grade alloy steel materials and manufacturing process, so that the transmission efficiency, noise control, service life and other aspects have been greatly changed, but also improve the performance of mechanical equipment and operation stability, for the user with a better experience.

Although Spiral bevel gears are widely used in mechanical equipment, due to high transmission efficiency, transmission stability, good carrying capacity and compact design structure, the equipment is more efficient during operation, and it also has a large savings in energy and space. This is also very high requirements for the manufacturing process, and it is very complex, but the precision of the product is also very high. The requirements for the manufacturing process are also very high and complex, with the following steps:

Design: Before processing, to determine the module of the gear, the number of gear, gear shape, pressure Angle parameters, etc., but also consider the functional requirements of the gear, transmission ratio, working environment and other factors.
Roughing: The first gear roughing, including turning, milling and other processes. At this stage, the shape of the gear is mainly processed into a preliminary shape.
Heat treatment: Heat treatment of the gear after rough machining, usually including quenching and tempering. Heat treatment can increase the hardness and strength of gear and improve its mechanical properties.
Precision machining: After heat treatment, precision machining of the gear, including grinding, hobbing and other processes. This step improves the precision and surface quality of the gear.
Detection and quality control: After the spiral bevel gear is processed, strict detection and quality control should be carried out. This includes checking the size, profile, surface quality, etc. of the gears to ensure that they meet design standards and customer requirements.

Spiral bevel gear manufacturing is more complex, so the need for precision equipment and technology, suitable processing methods and strict quality control, in order to produce high-quality gear to meet the real needs of customers.

In conclusion, choosing spiral bevel gear, quality is necessary, but also consider its performance, which will affect transmission efficiency and stability, carrying capacity, service life, SMI has nearly 30 years of customized processing experience, if you are interested, welcome to contact our professional team here.

Dross Press Cooling Head

Dross Press Cooling Head — Aluminum Dross Press Component Supply

The dross press cooling head is the component that determines how much aluminum you actually recover from hot dross. Aluminum dross oxidises continuously after leaving the furnace — the cooling head must contact the dross quickly, seal tightly against the pan walls, and extract heat fast enough to arrest that oxidation before free metal is lost irreversibly.

SMI manufactures dross press cooling heads as a standalone supply item and as part of complete aluminum dross press systems. As an aluminum recycling systems integrator with in-house material development, casting manufacture and on-site installation capability, SMI supplies cooling heads not simply as cast components to a drawing — but as engineered parts of a complete dross management solution. Cooled and uncooled variants are available across all geometries and sizes, matched to any dross pan or press frame currently in service.

Cooled and Uncooled Configurations

SMI dross press cooling heads are available in cooled and uncooled configurations. The appropriate variant is determined by the specific operational requirements of each installation — furnace type, dross generation rate, existing cooling infrastructure, press cycle objectives and overall system design. Cooled heads incorporate an integrated forced-cooling circuit and are the standard recommendation where maximising metal recovery and minimising oxidation time are the primary objectives. Uncooled heads are available for installations where the process configuration, existing infrastructure or operational parameters make active cooling in the head unnecessary. Both configurations are manufactured from the same SMI ATM series castable and are available across the full range of geometries. SMI application engineers will confirm the most suitable configuration based on a review of process parameters at the enquiry stage.

How the Cooling Head Determines Your Recovery Rate

The dross press works on a single principle: compress and cool hot dross as quickly as possible after skimming, before oxidation converts free metal into oxide. The cooling head is where that principle either succeeds or fails. Four variables determine performance in practice:

  • Seal geometry — the head profile must match the dross pan walls precisely. A poor fit allows dross to escape under pressure, breaks the thermal seal, and extends cooling time. Recovery loss from a worn or mismatched head is continuous and largely invisible until a direct measurement is taken.
  • Active heat extraction — forced cooling through an integrated circuit in the head body produces the cooling rates needed to arrest oxidation effectively. Passive ambient cooling is not sufficient for high-throughput operations.
  • Thermal shock resistance — the head enters dross at 700°C+ and is then cooled, dozens of times per shift. Material that cracks, spalls or deforms under this cycling degrades both seal geometry and cooling performance simultaneously — progressively and invisibly until failure.
  • Dimensional stability over service life — wear and thermal deformation on the mating face progressively degrade the head-to-pan seal. Material choice and casting geometry determine how long a head remains dimensionally effective before replacement is required.

SMI cooling heads are engineered around all four of these failure modes. The design objective is consistent, measurable performance across the full service life of the head — not only at initial installation.

Design and Manufacturing

Proprietary Anti-Thermal-Shock Castable — SMI ATM Series

The cooling head material is the central engineering decision and the point where most generic or cost-reduced heads fail prematurely. A dross press cooling head requires three material properties simultaneously: high thermal conductivity in the cooling zone to extract heat efficiently; low thermal expansion to resist cracking under repeated thermal shock; and abrasion resistance against the hard aluminum oxide particles present in all dross types. Standard refractory grades are optimised for one or two of these properties — not all three together.

SMI’s ATM series material is developed and produced in-house. The formulation is proprietary. Independent third-party test data and material samples are available to qualified buyers on request. This is the same material specification used across SMI’s full range of casthouse consumables — a production-grade specification with a 30-year operational record in aluminum casthouses across multiple continents.

Cast-In Cooling Circuit

The internal cooling channels in an SMI cooled head are formed during the casting process as part of the original geometry — not machined in afterward. Machined-in channels create walls of non-uniform thickness at the cooling zone, producing stress concentration points that initiate cracking under thermal cycling. Cast-in channels maintain consistent section thickness throughout the head body, producing more uniform heat extraction and longer dimensional stability under service conditions. The cooling circuit interfaces with the press cooling skid via standardised quick-connect fittings, allowing head replacement without draining the cooling loop.

Pan-Matched Geometry

SMI supplies cooling heads in circular, rectangular and custom cross-sections. Where a customer has an existing pan set, SMI manufactures replacement heads to match the pan geometry exactly. Where a complete new pan-and-head set is required, the two are designed together to optimise the seal profile and heat transfer path as a matched system. Dimensional tolerances on mating surfaces are held to ±1 mm. The pan-and-head combination is the single configuration decision with the largest impact on achievable in-house recovery rate — SMI designs and supplies both as a matched set for this reason.

Adaptation to Third-Party Press Installations

SMI cooling heads can be adapted to work with third-party and competitor press installations. This is a relevant supply option for operations with serviceable press frames where heads have worn, cracked or degraded, and full system replacement is not the preferred route.

A dimensional match on the head body and mating face is the starting point, not the complete solution. Hydraulic output, control system parameters, cycle timing and commissioning requirements vary significantly between press manufacturers and models — these are not visible in the physical dimensions of the head alone. SMI conducts a technical review of the existing press system specifications before confirming the adaptation scope and supply terms. This engineering review is SMI’s standard process for delivering a qualified, system-compatible solution.

The full delivery scope for third-party adaptations — engineering review, component manufacture, on-site installation and commissioning — is available as a single-source engagement. Buyers are requested to provide press equipment specifications, hydraulic system data and available press documentation at the enquiry stage.

Dross Type Coverage

Dross composition and behaviour under compression varies significantly by furnace type, alloy, flux practice and holding time. SMI cooling heads are specified and validated for the full range of industrially relevant dross and slag types:

  • Dry dross — primary smelter, low oxide content, high free metal fraction
  • Wet dross — holding furnace, alloying additions, variable metal content
  • Black dross — salt-flux secondary smelting, elevated chloride content
  • White dross — secondary smelter pre-treated, lower free metal content
  • Salt slag — rotary furnace with salt flux, requires specific head geometry and cooling duty
  • Rotary furnace slag — high temperature, lower aluminum content, variable composition

For dross with unusual characteristics — very high free metal, atypical particle size distribution, elevated impurity content — SMI application engineers review the process parameters and recommend the correct head geometry, cooling configuration and material grade before order placement.

Operational Benefits

Measurable Improvement in In-House Metal Recovery

Faster cooling means less oxidation between pressing cycles. Tighter compaction means fewer voids where trapped metal remains inaccessible. In-house recovery with a correctly configured pan-and-head system typically reaches 45–70%, substantially above unpressed or air-cooled dross handling. One practical constraint: if a dross pan sits for more than 15 minutes with hot dross before reaching the press, thermiting has already progressed significantly. Adequate press capacity relative to dross generation rate is a prerequisite — the cooling head design cannot compensate for insufficient press throughput.

Automated Cycle — Reduced Operator Exposure

The dross press cycle is fully programmable and automated: the head descends, holds at set pressure, cooling is confirmed, and the head retracts. No manual intervention is required during pressing. This removes operator exposure to radiant heat and fume, eliminates skill variability in dross handling, and reduces the specialist knowledge required for day-to-day operation and maintenance.

Schedulable Consumable Cost

Replacement heads are a known, foreseeable consumable cost — not an unplanned capital event. SMI ATM series material and robust casting process support extended and predictable service life under sustained thermal cycling. Replacement heads for common press formats are held in stock; non-standard and legacy press frame heads are manufactured on short lead times. Quality documentation — dimensional inspection reports, material certification, hardness test data — is supplied as standard with every order.
