摘　　要：通过对板坯连铸厂的调查发现连铸过程中铸坯的展宽现象在各厂都不同程度地存在,而且通过调整工艺参数来减小铸坯展宽量的方法不可行.根据结晶器的尺寸与铸坯展宽的关系,经推导得到矫正铸坯展宽的结晶器设置公式,结合在铸机出口位置处在线测量得到的铸坯宽度,可以算出矫正铸坯展宽的结晶器参数,从而精确控制铸坯的宽度.结合马鞍山钢铁公司坯连铸机的参数给出了一个具体应用实例.With the investigation of continuous slab casting factory,the slab broadening phenomenon of different degrees in the continuous casting process was found,and the broadening amount could not be corrected through the adjustment of process parameters. According to the correlation between the mould size and slab broadening,the mould setting formulas for correcting the broadening amount were obtained;combined with the width of slab measured at the exit of caster,the mould setting data for correcting the broadening amount could be obtained to control the width of the slab. A specific application is shown combined with the parameters of the secondary continuous slab caster in Ma'anshan Iron and Steel Co.,Ltd.
