板坯连铸机二切短流程生产线的开发和应用

Development and Application of Secondary Cutting Short Route ProductionLine of Slab Continuous Casting Machine

3#板坯连铸机二切工序一直不能正常工作 ,采用了在线切割工艺 ,根据切割条件和切割周期等参数 ,结合板坯连铸出坯线短、车间小的特点 ,确定二切机的位置在距一切终止点 15 m处。改进了清渣系统 ,采取了升降挡板和定尺板相结合的定尺方式 ,设定不同的辊道运输速度等措施 ,保证了二切设备的正常运行 ,实现了板坯的热送热装。

Secondary cutting process of No.3 slab continuous casting machine cannot be to normal work for a long time. Through adopting some measures included improving scale removing system, using sized method combined up-down plate with sized plate, establishing differential transporting speed of roller bed, etc, the normal operation of secondary cutting equipment is ensured and the hot-transporting and hot-charging of slab is achieved.
