High-strength acid-resisting abrasion-resisting castable used for front end of blast furnace water granulated slag punching groove
The invention belongs to the field of refractory materials, and particularly relates to high-strength acid-resisting abrasion-resisting castable used for the front end of a blast furnace water granulated slag punching groove. The castable is prepared from, by mass, 40-60% of compact corundum, 10-30% of acid-resisting powder, 10-20% of calcium aluminate cement, 1-7% of chromium oxide, 1-5% of heat-resistant steel fibers, 0.05-0.2% of organic explosion-proof fibers, 0.5-2% of boron carbide, 2-7% of activated silica micro powder, 2-7% of activated aluminum oxide micro powder, 0.2-0.5% of compound polycarboxylic acid dispersing agents and 0.1-0.5% of flowability retention agents. The castable has high-strength acid-resisting abrasion-resisting performance and is used for replacing a traditional blast furnace water granulated slag lining material, and the purposes of prolonging the service life of a lining body, lowering the cost and protecting environment can be achieved.
