结合现场实测,在分析镀锌机组拉矫机拉矫工艺的基础上,分析得出了导致轴头断裂的主要原因是工作辊辊身及轴头直径小、喷嘴堵塞并引起润滑性能下降、带钢表面锌渣及辊系预装精度低等。通过采取增大工作辊辊身及轴头直径、增加喷嘴流量和减小辊系预装间隙的措施使得辊身强度提高、辊面润滑改善和工作辊弯曲变形量减小,改善了拉矫工作辊的工作条件和受力状态。现场生产应用效果表明,所采取的措施解决了轴头断裂的问题。
On the basis of analyzing the straightening and straightening process of galvanizing machine, the main reason of the fracture of the shaft head was analyzed. The main reason of the fracture of the shaft head is the small diameter of the roller body and the shaft of the work roll, the blockage of the nozzle and the decrease of the lubrication performance. Zinc slag on the steel surface and roller pre-installed low accuracy. By taking measures to increase the work roll body and shaft head diameter, increase the nozzle flow rate and reduce the pre-assembly gap of the roll system, the strength of the roll body is improved, the lubrication of the roll face is improved, the bending deformation of the work roll is reduced, and the straightening work is improved Roller working conditions and the state of stress. The field production application shows that the measures taken to solve the problem of shaft fracture.
