摘　　要：讨论了异型坯连铸机拉坯阻力的计算方法,将异型坯视为两个板坯的组合,重点是依据金属的弹性及高温蠕变特性,计算了二冷段凝固坯壳的鼓肚值及支承辊矫平坯壳鼓肚的阻力、拉矫辊与铸坯间的滚动摩擦阻力,计算结果与实际情况相吻合。The calculating method of withdrawal resistance of beam blank caster is proposed. The beam blank is regarded as two slabs. Based on the elastic and creep properties of steel at casting temperature, the withdrawal resistance caused by leveling bulging and rolling friction of withdrawal rolls and hot steel is discussed. The result is satisfactory.
