Focusing on engineered products for the Aluminum Industry, McKeown has been supplying refractories and other engineered products worldwide.
Specifically, McKeown International offers Si3N4 Bonded Silicon Carbide Block, Silicon Carbide Mortar/Castable, Anthracite Block, Insulating Brick, Cathodes, Combo Blocks, Calcium Silicate Board, Superduty Fireclay, and High Aluminum Brick.
Anthracite Block and Calcium Silicate Insulating Board
Anthracite Block is made from electrically calcined anthracite and other binding agents. The product has low ash content, low thermal conductivity and high hot strength. The product has accurate dimensions from precise machining process. It can be widely used in the electrolytic smelting of aluminum.
Calcium Silicate Insulating Board is a product family with three (3) grades. It has combined advantages of light weight, low thermal conductivity and high temperature resistance. Its lower shrinkage provides small deformation within working temperature range. It is recommended to be used as thermal insulation or as backing material of refractory bricks in the industrial furnaces.
Aluminum Furnace Brick – Smelting Pot Refractories
MH 70 and MH 80 are made with high calcined bauxite, and offer high density and strength. Its high refractoriness provides good performance for the brick under high temperature operations. It offers good resistance to slag attack and thermal shock. They are primarily used in the steel ladle and aluminum furnace.
MSC24 is made with high purity raw material and fired at high temperature to achieve excellent hot strength and thermal conductivity. It offers excellent resistance to oxidation and erosion/corrosion from cryolithic bath. It is ideal to be used as the refractory lining for the side wall of the aluminum smelting pot.
DSD127 is a super duty fireclay brick fired at high temperature with high density. It is manufactured by a dry press process. This product has low iron, high refractoriness and hot strength, excellent volume stability and corrosion resistance. It is ideal for use in the furnace application where high temperatures are applied for extended periods and severe chemical corrosion exists.
Carbon Baking Furnace Fireclay Brick
Ml Insulating Brick
Ml Insulating Brick has low thermal conductivity and low heats storage for reduced fuel consumption and efficient production. Products have high strength, low shrinkage, and good resistance to spalling. It is suitable as backup insulating lining in furnaces and heated equipment.
