运用焊接技术修复大型混捏机主轴工艺的实践

Practice of Using Welding Technology to Repair the Main Shaft of Kneading Machine

本文介绍了混捏机主轴开裂的情况,通过对其材料的技术性能,钢的焊接性能的分析,确定了运用手工焊的方案和焊接材料以及焊接施工工艺,并通过实践,证明了该技术的可行性。该工程中由于采用了特殊焊剂和先中间后两边的焊接方法,并采用了有效的防变形措施,严格执行焊接工艺规范,严格控制焊接顺序,经焊后实测,完全满足了技术要求,达到了预期的效果,节省了大量的外汇。

In this paper, the main shaft cracking of kneading machine is introduced. Through the analysis of the technical performance of the material and the welding performance of the steel, the scheme of using manual welding, the welding material and the welding construction process are confirmed, and the practice is proved that the technology Feasibility. Due to the special flux and the welding method on both sides of the middle of the project, effective anti-deformation measures are adopted, the welding procedure specifications are strictly enforced, the welding sequence is strictly controlled, and the measured results after welding completely meet the technical requirements Expected results, saving a lot of foreign exchange.
