Steel ladle aluminum-magnesium refractory mortar capable of recycling refractory dust collection powder and preparation method thereof
The invention discloses steel ladle aluminum-magnesium refractory mortar capable of recycling refractory dust collection powder and a preparation method thereof. The steel ladle aluminum-magnesium refractory mortar is prepared from the following raw materials in percentage by mass: 5.0%-90.0% of refractory dust collection powder, 5.0%-30.0% of corundum fine particles with the particle size of 0.5-0.15 mm, 2.0%-20.0% of fused magnesia fine particles with the particle size of 0.5-0.15 mm, 1.0%-10.0% of corundum micro powder and/or alpha-type activated alumina micro powder, 0.5%-5.0% of silica micro powder, 0.1%-1.5% of a water reducing agent, 0.01%-1.0% of a plasticizer and 0.01%-1.0% of a preservative. The preparation method comprises the following steps: firstly, adding the refractory dust collection powder into a mixing mill, then adding the water reducing agent, the plasticizer and the preservative, uniformly mixing, then adding the other raw materials, continuously uniformly mixing, and discharging to obtain the steel ladle aluminum-magnesium refractory mortar.
本发明公开了一种耐材吸尘粉回收利用的钢包铝镁耐火泥及其制备方法。以质量百分比计，所述钢包铝镁耐火泥的原料组成包括：耐材吸尘粉5.0％～90.0％，粒度为0.5～0.15mm的刚玉细颗粒5.0％～30.0％，粒度为0.5～0.15mm的电熔镁砂细颗粒2.0％～20.0％，刚玉微粉和/或α型活性氧化铝微粉1.0％～10.0％，硅微粉0.5％～5.0％，减水剂0.1％～1.5％，增塑剂0.01％～1.0％，保存剂0.01％～1.0％。所述制备方法包括：先将耐材吸尘粉加入到混碾机内，然后加入减水剂、增塑剂、保存剂混合均匀后，再加入其余原料，继续混合均匀，出料即得所述钢包铝镁耐火泥。
