钢包工作层用浇注料
The castables of the ladle working lining
　　刚玉尖晶石整体浇注料是以刚玉为主要原料，添加部份尖晶石或镁砂原料，以水泥或微粉为结合剂的不定型产品，使用中具有良好的整体性、抗侵蚀性及热震稳定性优的特点。
　　The corundum-spinel based castables is one integral casting refractory material of the ladle, using corundum as main material and incorporating certain spinel or magnesia materials, bound by the cement or micro-powder. This unshaped refractory has good integrity,excellent corrosion resistance and thermal shock stability.
