The decription of aluminum with carbon bricks


Carbon bricks:
Anthracite or coke as the raw materials of brick, a special processing products.
Firing porous aluminum with carbon bricks:
Dense alumina grade bauxite clinker, high temperature electric calcined anthracite, graphite, silicon carbide is the main raw materials, phenolic resin or high temperature coal tar pitch binder and mixing additive powder, high-pressure molding, high temperature sintering in a reducing atmosphere, fine grinding of microporous aluminum carbonaceous products, used for lining masonry blast furnace belly stove waist and lower part of the furnace body.
of carbon refractory
By a neutral refractories, coke or heat-treated anthracite and coal tar firing in the reducing flame. The carbon content of about 88% -90%. With high thermal stability, refractoriness, thermal conductivity and electrical conductivity. Molten metal and slag erosion resistant, but susceptible to oxidation. Mainly used for the molten metal and furnaces and stoves, body contact, such as the furnace and the bottom of the blast furnace, molten non-ferrous metal shaft furnace, fused calcium carbide, ferroalloy electric furnace.
