本发明公开了一种贝氏体钢轨的焊接生产方法,通过调整焊接起拱角度,设计焊后回火工艺保证了贝氏体钢轨的焊接接头的平直度,提高贝氏体钢轨焊接接头的组织应力,提高贝氏体钢轨焊接后的使用寿命,降低了换轨大修费用。
The invention discloses a welding production method of bainitic steel rail. By adjusting the welding camber angle and designing the post welding tempering process, the flatness of the welded joint of bainitic steel rail is ensured, the organizational stress of the welded joint of bainitic steel rail is improved, the service life of bainitic steel rail after welding is improved, and the rail replacement overhaul cost is reduced.
