Bottom aluminum-magnesia carbon brick and preparation method thereof
The invention provides a ladle bottom alumina-magnesia carbon brick. The ladle bottom alumina-magnesia carbon brick comprises 50-75 wt% of a waste base material, 5-10 wt% of fused magnesite, 3-6 wt% of white corundum, 5-10 wt% of graphite, 5-10 wt% of composite magnesium aluminate spinel and 0-5 wt% of an antioxidant, and 2-3 wt% of resin. The invention also provides a preparation method of the ladle bottom alumina-magnesia carbon brick. The waste base material in the ladle bottom alumina-magnesia-carbon brick provided by the invention is one of the waste argon brick cup reclaimed material and the waste corundum carbon-free precast block, the main components of the waste base material are corundum and spinel, the effects of erosion resistance and slag erosion resistance of corundum can be continuously exerted, the cost is also reduced, meanwhile, the addition amount of fused magnesite and composite magnesia-alumina spinel is added and controlled, and the cost is reduced. And the erosion resistance and penetration resistance of the ladle bottom alumina-magnesia carbon brick can be obviously improved.
本发明提供了一种包底铝镁碳砖，包括：废弃基料50～75wt％，电熔镁砂5～10wt％，白刚玉3～6wt％，石墨5～10wt％，复合镁铝尖晶石5～10wt％，抗氧化剂0～5wt％；树脂2～3wt％。本申请还提供了包底铝镁碳砖的制备方法。本申请提供的包底铝镁碳砖中废弃基料为废氩座砖再生料和废刚玉无碳预制块中的一种，其主要成分为刚玉和尖晶石，不仅能够继续发挥刚玉耐冲刷、抗渣侵蚀的作用，也降低了成本，同时加入并控制电熔镁砂和复合镁铝尖晶石的加入量，可明显提高包底铝镁碳砖的抗侵蚀、抗渗透能力。
