Refractory material for steel smelting and preparation method of refractory material
The invention relates to a refractory material for iron and steel smelting. The refractory material is characterized by comprising the following raw materials in parts by weight: 60-70 parts of cast stone powder, 40-45 parts of quartz powder, 35-45 parts of bauxite, 30-40 parts of brucite powder, 30-35 parts of powdered activated carbon, 20-25 parts of vesuvianite powder, 20-25 parts of asbestos powder, 5-8 parts of sodium bicarbonate powder and 10-15 parts of a binding agent. The refractory material for iron and steel smelting prepared by the invention is wide in use temperature range and good in thermal shock resistance, can be prevented from being eroded by slag, and also can be prevented from reacting with CO, SO2, CO2, CH4, H2O and volatile oxides and salts in metals.
一种钢铁冶炼用耐火材料，其特征在于，所述耐火材料的原材料按重量份计，包括：60‑70份铸石粉、40‑45份石英粉、35‑45份铝矾土、30‑40份水镁石粉、30‑35份粉状活性炭、20‑25份火山石粉、20‑25份石棉粉、5‑8份碳酸氢钠粉、10‑15份结合剂。本发明制备的钢铁冶炼用耐火材料使用温度范围宽，抗热震性能好，能够避免耐火材料受炉渣的侵蚀，同时也避免耐火材料与CO、SO2、CO2、CH4、H2O以及金属中可挥发的氧化物及盐类发生反应。
