Casting material for molten iron ladle is a refractory material made of a variety of inorganic non-metallic materials through scientific proportioning, mixing, molding, curing and other processes.
It is mainly used to withstand the scouring and erosion of molten iron or other molten metals in a high temperature environment to ensure the smooth progress of the production process.
(1) High temperature stability
(2) Good erosion resistance
(3) Good thermal shock resistance and high oxidation resistance
(4) Convenient construction
(1) Ductile iron ladle
(2) Casting gray iron ladle
(3) Forgeable casting ladle and other refractory working linings for transporting high-temperature molten iron
