Explosion-proof ASC (Al2O3-SiC-C) refractory castable for iron ladles
The invention discloses an explosion-proof ASC (Al2O3-SiC-C) refractory castable for iron ladles, which comprises the following components in percentage by mass: 85-95% of low-cement combined ASC casting base material, 1-3% of aluminum powder, 2-10% of explosion-proof fiber, 1-10% of basic emulsion antiknock agent and 1-10% of organic gas former, totaling 100%. The low-cement combined ASC casting base material is composed of low cement, ASC and a binder. By adding the metal Al powder, explosion-proof fiber, basic emulsion antiknock agent and organic gas former, the explosion resistance of the refractory castable for iron ladles is greatly enhanced, and the casting hardening time is effectively controlled, thereby solving the problems of expansion and blowout of the casting due to over-quick hardening and over-slow hardening of the castable. The refractory castable has the advantages of high use safety, long service life and low consumption, is convenient for construction and repair, is an important assurance for stable and smooth production in the furnace, and changes the working environment of the steel plant.
