柳钢R8m罗可普型方坯连铸机由武汉钢铁设计研究院设计,两台连铸机分别于1993年12月及1994年4月热负荷一次试车成功。该连铸机采用了刚性引锭杆及无辊浇铸工艺。刚性引锭杆起动平稳,不会抖动,能很好地适应结晶器液面自动控制,实现自动开浇,减少开浇漏钢事故。刚性引锭杆寿命长,加上系统机械设备简单,减少了维修费用。采用刚性引锭杆可取消结晶器下方足辊及二冷段中的导向装置,实现无辊浇铸新工艺。
Liuzhou Iron and Steel R8m Rocco billet continuous casting machine designed by the Wuhan Iron and Steel Design and Research Institute, two caster respectively in December 1993 and April 1994 heat load test success. The continuous caster uses a rigid dummy bar and non-roll casting process. Rigid dummy bar start stable, will not shake, can be well adapted to the mold automatic control of liquid to achieve automatic pouring, to reduce open cast steel accidents. Rigid dummy bar long life, coupled with the system mechanical equipment is simple, reducing maintenance costs. The use of rigid dummy bar can be eliminated under the foot roller and second cooling section of the guide device to achieve a new process without roller casting.
