首秦号板坯铸机拉矫机万向联轴器改造

Renovation of Straightening Machine Universal Coupling in No.3 Continuous Caster of Shouqin

铸机拉矫机万向联轴器主要是将减速机扭矩传递给扇形段驱动辊,为连铸机提供拉矫力。首秦3号连铸机万向联轴器伸缩位置距离扇形段驱动辊连接法兰较近,在二冷室内极易腐蚀锈死,不易拆卸;同时万向联轴器与扇形段驱动辊法兰连接处螺栓极易松动,造成引锭杆下沉,严重影响生产。对拉矫机万向联轴进行技术改造,解决了万向联轴器伸缩腐蚀锈死和万向联轴器与扇形段驱动辊法兰盘螺栓容易松动的问题。

The main function of universal coupling of caster straightening machine is transferring torque from reducer to segment driven roller. This torque drives the slab to go smoothly in segments. Shouqin No. 3 caster universal coupling telescopic position is very close to the segment driven roller connecting flange, and it is corroded easily in the second cooling room, not easy to be disassembled. At the same time, universal joint and segment driven roller flange bolts are easy to loose, causing the dummy bar sinks, which seriously affected the normal production. So af- ter the universal coupling renovation, the corrosion of universal coupling telescopic and the easy loosing of driven roller flange bolt are solved.
