Aluminium

Aluminium is one of the most widely used metals on earth after iron owing to its unique properties such as low weight, high strength, superior malleability, easy achining, excellent corrosion resistance, and good thermal and electrical conductivity.Aluminium is infinitely recyclable and nearly 70% of all Aluminium ever produced in the world is still in use today.

refractory solutions for aluminium industry

  • PRIMARY ALUMINIUM

  • SECONDARY ALUMINIUM

  • CASTING

different units of aluminium plants are:

  • Flash Calciner

  • Rotary Kiln

  • Anode Baking Furnace (ABF)

  • Pot Furnace / Cell

  • Melting & Holding Furnace

  • Induction Furnace

  • Transfer Crucible

  • Launder / Trough

anode baking furnace

Refractories are selected for ABF application based on various designed set of specifications. The flue wall brick plays an important role for ABF application due to the high cost of the refractories including the material replacement and initial investment on the furnace construction. refractory lining of anode baking furnaces suffers from severe corrosion by alkalis, sulphur, fluorine etc. Apart from chemical attack, the flue wall and head wall bricks are also subjected to mechanical impact, thermal cycling load and high temperature deformation. Progress has been made for the development of innovative products (with the base raw materials fused mullite, andalusite, tabular and reactive alumina etc.) having unique features like low gas permeability, high creep resistance, high HMOR value at 1300°c, resistance to co gases and alkalis, good thermal shock resistance etc.

High alumina bricks, with formulations based on calcined fireclay, mullite and andalusite, are used as side walls and bottom linings.

Dense castables, with formulations based on calcined clay, are used as top blocks.

Tilting melting & holding furnace

Melting furnaces serve the purpose of supplying casting machines with molten aluminium on a steady and continuous tempo.When molten aluminium comes in touch with refractories at the bath zone, it can cause fast and heavily corrosion.

Products from the following lines are recommended:

  • High Alumina bricks, with formulations based on mullite and bauxite, are used at the bath zone, roof and side walls.

  • Low cement castables with formulations based on mullite, andalusite and bauxite, are used at the bath zone, roof & side walls and as burner linings.

  • Ultra-low cement castables with formulations based on mullite, andalusite and bauxite, are used at the bath zone, roof, side walls and as burner linings.

  • Non cement castables with formulations based on mullite, bauxite and sintered alumina, are used at the bath zone, roof, and side walls.

  • Dense with formulations based on mullite and tabular alumina, are used at the roof and side walls.

  • Low cement gunning materials with formulations based on chamotte, mullite, bauxite and corundum, are used at the roof and side walls.

  • Medium cement gunning materials with formulations based on mullite, are used at the roof and side walls.

  • Insulating castables with formulations based on vermiculite and perlite, for use as roof and door insulation.

  • Insulating castables & gunning materials with formulations based on light weight chamotte, for use as roof, door and general insulation.
