Air brick containing corundum ceramic balls and preparation method thereof
The invention discloses an air brick containing corundum ceramic balls and a preparation method of the air brick. The adopted technical scheme is as follows: the raw materials comprise the following components in parts by weight: 60-70 parts of corundum ceramic balls, 5-10 parts of MgO.Al2O3 spinel micro powder, 3-12 parts of mullite, 2-6 parts of alpha-alumina micro powder, 0-2 parts of zirconia micro powder, 0-5 parts of chromic oxide micro powder and 4-6 parts of a binding agent. The raw materials are mixed according to the weight ratio, the mixed materials are added into an elastic mold and sealed, molding is carried out under an isostatic pressing machine, a green brick obtained after mold removal is sent into a drying kiln to be dried, and then firing is carried out at the high temperature. The air brick provided by the invention has the characteristics of small pores, uniform pore size, high high-temperature strength, erosive wear resistance, and good molten steel and steel slag erosion resistance.
本发明公开了一种含刚玉陶瓷球的透气砖及其制备方法。采用的技术方案是：原料及重量配比为：刚玉陶瓷球60～70份、MgO·Al2O3尖晶石微粉5～10份、莫来石3～12份、α‑氧化铝微粉2～6份、氧化锆微粉0～2份、氧化铬微粉0～5份、结合剂4～6份；以上原料按重量配比混料、混好的物料加入弹性模具并封口，于等静压压力机下成型，将拆模后的砖坯送入干燥窑内进行干燥，然后在高温下烧成。本发明的透气砖具有气孔较小、气孔大小均匀，高温强度高，耐冲刷磨损，抗钢液钢渣侵蚀性好的特点。
