Impact-resistant anti-erosion energy-saving refractory material for ladle
The invention discloses an anti-impact anti-erosion energy-saving refractory material for a ladle, which is prepared from the following raw materials in percentage by mass: 35 to 65 percent of electro-fused mullite aggregate, 7 to 20 percent of tabular corundum, 0.8 to 5 percent of aluminum oxide hollow spheres, 0.3 to 3 percent of waste mullite insulating brick reclaimed material, 6 to 12 percent of zirconium mullite powder, 0.8 to 4 percent of organic modified silicon resin, 1 to 5 percent of mesophase pitch powder and 0.8 to 4.7 percent of silica powder. The invention relates to a cement mortar which comprises the following components in percentage by weight: 3-8% of pure calcium aluminate cement, 0.01-0.1% of isopropanol, 0.03-0.13% of sodium methylene dinaphthalene sulfonate and 0.01-0.3% of aluminum sulfate solution. The energy-saving refractory material for the ladle overcomes the limitation that the existing refractory material for the working layer of the ladle is easy to oxidize and erode, poor in thermal shock impact resistance, poor in heat preservation property and the like, and meets the process requirement of adding scrap steel into the ladle under a large scrap steel ratio and the requirement of extreme energy efficiency at the present stage.
本发明公开了一种铁水包用抗冲击抗侵蚀节能型耐火材料，其原料组成按质量百分比计包括：电熔莫来石骨料35～65％，板状刚玉7～20％，氧化铝空心球0.8％～5％，废旧莫来石保温砖回收料0.3～3％，锆莫来石粉6～12％，有机改性硅树脂0.8～4％，中间相沥青粉1～5％，硅微粉0.8～4.7％，纯铝酸钙水泥3～8％，异丙醇0.01～0.1％，亚甲基二萘磺酸钠0.03～0.13％，硫酸铝溶液0.01～0.3％。该铁水包用节能型耐火材料克服了现有铁水包工作层耐火材料易被氧化侵蚀，抗热震冲击能力差，保温性差等局限性，满足了大废钢比下铁水包加废钢的工艺要求及现阶段极致能效的需求。
