大型G115钢弯头成型工艺研究

Research on the Forming Process of Large G115 Steel Elbows

本文主要阐述了大型G115钢弯头中频感应加热弯管和热挤压成型两种工艺方法,并进行两种工艺方法的试验验证,摸索出了G115钢热成型控制温度及热处理工艺,具有了高等级参数锅炉制造的技术储备。

This paper mainly expounds the formation of the large G115 steel elbows by,respectively, medium frequency induction heating process and hot extrusion forming process.The control temperatures and the heat treatment process adequate for G115 steel elbow formation are identified through tests of the two process methods, ensuring the technology preparation for the manufacturing of boilers with high-grade parameters.
