Abstract 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 after the universal coupling renovation, the corrosion of universal coupling telescopic and the easy loosing of driven roller flange bolt are solved.
