摘　　要：介绍了梅山钢铁公司2号板坯连铸机的概况及结晶器液面波动的特点,认为周期性波动的原因是板坯鼓肚和二冷区等间距辊子排列造成的,并受到工艺条件的影响。研究结果表明:液面波动周期与辊距成正比,与拉坯速度成反比。该结论在生产中通过对扇形段上框架位移和拉杆受力的测量,得到了验证,对板坯连铸机设计和生产有一定的指导意义。The present paper introduces the general situation of the No. 2 Slab Caster in Meishan Iron ＆ Steel Works as well as the feature of the mould level fluctuation of the caster and it＇s proved that casting blank bulging and disarrangement of the equal space rollers in the 2^nd cooling zone are primary causes to the periodical fluctuation, and the process conditions may have effect on it to some extent. Results show that the mould level fluctuation is in direct proportion to the roller space and in inverse proportion to the drawing speed. This conclusion is verified by measuring displacement of the frames in the segment section and load on the pull rod. It is of guiding significance for the continuous caster design and production in the future.
