现代连轧管机组用芯棒生产技术

Production Technologies of Mandrel Used on Modern Mandrel Pipe Mills

论述了现代连轧管机组主要变形工具芯棒的工况条件、失效形式,芯棒消耗量的大小直接影响无缝管的生产成本,根据芯棒的服役条件确立选材原则、制造工艺、规格。

It is elaborated the working conditions, as well as failure mode of mandrel used on modern mandrel pipe mills, and the consumption of mandrel directly influences the production costs of seandess tubes. Moreover, the principles of selecting materials, manufacturing engineering, and specifications are determined according to the terms of service for mandrel.
