钢包浇注料：钢包浇注料具有强度高、抗震性好、耐侵蚀和体积稳定性好等特点。适用于钢包包底、包壁、渣线等部位。特别是利用电新技术开发的刚玉尖晶石浇注料，在大电炉、大转炉精炼钢包包底、包壁等部位使用可明显提高钢包寿命。 The products are characterized by high intensity, good resistance to heat shock and corrosion and volume stability. They are fit for such parts as ladle bottom, wall and slag line. Especially the boule spinel castable materials developed by the latest technology can prolong the ladle service life noticeably when used at the bottom and wall of ladle's for big electric furmace, converter and finer.
