摘　　要：研究了可膨胀石墨含量和温度对复合保护渣导热系数的影响规律。研究结果可用于：计算钢锭模帽口散热及帽口内钢水凝固时间；The effect of expanding graphite content and temperature on the thermal conductivity of compound mold flux is studied through laboratorial measures.The data obtained can be used to calculate the time of relevant heat transfer on riser heads,and of solidification of steel inside and to determine the best amount of flux needed and best content of expanding graphite in the flux

关 键 词：可膨胀石墨 温度 保护渣 导热系数
