Low cement castables for aluminum melting furnace
Low-cement castables for aluminum melting furnaces use coke gemstone clinker, high-alumina bauxite clinker, fused corundum, silicon carbide, etc. as the main raw materials, and use bauxite cement or pure calcium aluminate cement as the binder. A ready-to-use low-cement castable. Low-cement castables for aluminum melting furnaces have the characteristics of convenient construction, good overall performance, and long service life.
The anti-seepage of aluminum water on the hearth of the aluminum melting furnace is generally poured with clay-based low-cement castables with low Ai2O3 content and compact structure;
The upper furnace wall and furnace roof of the aluminum melting furnace are generally poured with high-alumina and low-cement castables with high Al2O3 content, low impurity content, and compact structure;
Aluminum melting furnace doors, furnace door frames, and fire opening doors are generally casted with silicon carbide low-cement castables with good thermal conductivity and good thermal shock resistance stability;
The bottom of the aluminum melting furnace, the lower furnace wall, the slag removal slope, and the lining of the aluminum water outflow tank are generally poured with non-stick aluminum corundum low-cement castables with good wear resistance and long service life.
