Company Overview

STAS specializes in the development, fabrication and commercialisation of technologically advanced equipment for the aluminum industry according to international manufacturing standards. Our clients are serviced by a network of representatives in the Americas, Europe, Asia, Australia and South Africa.

STAS is a recognized leader in its innovative abilities to supply specialized equipment according to customer needs to improve quality, reduce pollution and lower costs, using the latest in programmable automatic controls. Examples include dross coolers, molten metal jet stirrers, bed filters, HF monitors, gas injection fluxing units and crucible cleaners.

STAS is located in Quebec, where 2 000 000 tonnes of aluminum alloys are produced in the most technologically advanced plants in the world. World-class research facilities close by, such as the Alcan R&D Centre, the Centre de recherche du industrielle and the University of Quebec provide STAS with many opportunities to develop the latest technologies for the aluminum industry. STAS is certified ISO 9001.

• Granulation Of Alumina Dust And Its Reintroduction Into The Calcination Process

  A new technology that allows the granulation of alumina dust and its reintroduction into the calcination process during the production of alumina. Alumina is used principally in the electrolysis process in aluminum smelters.

• The Inert Gas Dross Cooler (igdc)

  In an attempt to stop aluminum oxidation many methods of cooling dross have been developed over the years. Until now, each method had developed undesirable side effects: high maintenance, dust and smoke, unpleasant working conditions, high capital investment, dross in close proximity to water, etc. After years of development within Alcan, the Inert Gas Dross Cooler (IGDC) has been perfected and is now commercially available. The IGDC solves the problems of aluminum dross simply and effectively.

  The heart of the IGDC is a large thermal heat sink in the form of a cast steel pan into which dross is skimmed. When required, drainage holes can be provided for direct molten metal recovery during skimming. As soon as a pan is filled, it is moved directly into an Inert Gas Cooler where further oxidation is prevented by the injection of argon gas.

  The gas performs no cooling as such; it simply excludes oxygen. Most of the heat is absorbed by the pan. The remainder of the cooling is by radiation and convection from the hood to the surrounding environment.

  The IGDC is very simple, safe, and efficient! It is made cost effective by improving the metallic recovery from dross whilst simultaneously upgrading the plant environment. The many benefits of the system are:

  Excellent metal recovery by reducing oxidation;

  Very safe process (no water);

  Low operating and maintenance costs;

  Low capital cost;

  Excellent workplace environment;

  No dedicated operator is required;

  Readily accepted by plant operators.

  The installation requires no special infrastructure and is adaptable to many needs by adding modular units.

• Treatment Of Aluminum In A Crucible (tac)

  Aluminum alloys need to meet ever more stringent quality requirements, particularly for the elimination of alkalis and alkaline earth metals. Chlorine is traditionally used to eliminate these impurities but is a pollutant and a hazard.

  The TAC, designed and commercialized by STAS, successfully reduces Na and Li contents to specification levels in less than 10 minutes without the use of chlorine. TAC achieves these objectives by injecting AlF3 directly into the molten metal in the crucible.

  Advantages include: Low cost; No chlorine is used; No need to transfer to another crucible; Extremely rapid (less than 10 minutes); Automatic P. L. C. operation; Integrated dust collector system.
