用于感应熔炼炉衬的耐火材料
摘要：
本发明涉及一种用于感应熔炼炉衬的耐火材料，该材料包括以重量计的以下原料：10~12份的6~8mm镁砂颗粒、12~15份的9~12mm镁砂颗粒、20~26份的0.05~0.06mm镁砂颗粒、5~6份的45~48μm镁砂粉、8~15份的电熔水晶细粉和微粉，3~5份的碳化硅，0.3~0.5份的外加剂，外加剂是硼酸和硅酸钠以1:3的重量比的混合物。不同粒径的镁砂颗粒复合在一起，降低了该材料的制造成本（本材料总体可节约成本10%左右），经过和其他组分的有效复配，提高了产品的耐火性能和使用寿命，炉龄可以提高一倍以上。
摘要（英）：

The present invention relates to a fireproof material for an induction melting furnace lining, wherein the fireproof material comprises the following raw materials by weight: 10-12 parts of 6-8 mm magnesia particles, 12-15 parts of 9-12 mm magnesia particles, 20-26 parts of 0.05-0.06 mm magnesia particles, 5-6 parts of 45-48 [mu]m magnesia powder, 8-15 parts of electrofused crystal fine powder and micro-powder, 3-5 parts of silicon carbide, and 0.3-0.5 part of an admixture, wherein the admixture is a mixture comprising boric acid and sodium silicate according to a weight ratio of 1:3. According to the present invention, the magnesia particles having different particle sizes are compounded so as to reduce the manufacturing cost of the material (the total material cost can be saved by about 10%), and with the effective compounding with other components, the fire resistance and the service lifer of the product can be improved, wherein the furnace age can be prolonged by more than 1 time.
