１前言铸坯切割装置的任务是把完全凝固并矫直后的铸坯切成所需的定尺或倍尺长度。因为连续铸钢中的切割过程是在铸坯连续运动中完成的，所以切割装置必须与铸坯实行严格的同步运动。另外在多机多流连铸机中，对切割装置的横向轮廓尺寸有所限制。现有的铸坯切割方法有两类：火 1 Introduction Billet cutting device’s task is to fully solidified and straightened cast slab cut into the required length or double length. Because the continuous casting process in the continuous casting process is completed in the slab, so the cutting device must be implemented with the slab strictly synchronous movement. In addition, in multi-machine multi-strand caster, there is a limit to the horizontal profile size of the cutting device. There are two types of existing billet cutting methods: fire
