Embodiment Construction
[0016] Below in conjunction with embodiment, the present invention will be explained clearly and completely:
[0017] The wear-resistant refractory castable of the present invention is composed of 25-30% of ferrochrome slag, 35-42% of microporous mullite particles, 6-16% of mullite fine powder, 0.5 -3% silica micropowder, 1-3% calcium aluminate cement, 8-15% binder, 2-5% reinforcing agent, 20-35% spinel micropowder, 5-8% Refractory mud, 0.1-0.35% of polycarboxylate dispersant, 0.1-0.15% of water reducing agent and 0.05-0.15% of organic explosion-proof fiber; the above raw materials are ground to the desired particle size by a grinding machine, and then passed through The mixing mixer is uniformly mixed, then vibrated and cured in the mold, and finally heat-treated at 1500-1800 degrees for 3-6 hours to obtain the castable. The castable can effectively cope with high temperature and erosion, prolong its service life, and ensure the effect of the castable in use. The castable i...
