钢铜熔敷焊接振动时效技术的研究与应用

Research and application of VSR in copper and steel re-melt deposit welding

结合北方红阳工业集团有限公司的生产实际情况,从节能降耗和降低生产成本的前提出发。分析采用感应加热方式使预置在钢基体上的铜环整体熔化并与钢基体发生冶金结合,而钢基体不熔化的铜钢感应熔敷焊接方法进行加工的产品,因为加热不均匀等因素产生残余应力从而造成后期工件加工薄壁后产生变形,影响了工件的尺寸稳定性,无法满足产品的设计要求。于是采用振动时效技术替代热时效,经过多次的实际应用解决了工件内部加工应力的问题,使工件不再变形,提高了工件的尺寸稳定性,满足了产品加工和装配要求,提高了生产效率,并达到节能减排的效果。

Combing with my company production practice,and costing the energy consumption and the production cost,this paper analyzes that processing products by re-melt deposit welding of using induction heating way that makes overall melted copper ring in steel substrate and steel happens metallurgical combination, and steel base don＇t be melt because of asymmetric~ heating and other factors,and produce the residual stress.Affect dimension stability of work piece,and the processing cannot satisfy the design of the product requirements after machining the thin-walled work piece and cause the deformation.Using of VSR substitute for thermal aging,solves the problem of internal processing stress,and makes the work piece no deformation,improves the dimension stability, meets product requirements of processing and assembly,and improves the production efficiency,achieves the effect of energy saving and emission reduction by many practical applications.
