无缝钢管冷拔模具渗金属处理

METAL-IMPREGNATING OF COLD DRAWINC DIE OF SEAMLESS PIPES

本文介绍了一种新的无缝钢管冷拔模具表面处理方法——渗金属技术。论述了渗金属工艺,并对工件表面形成的碳化物层进行了较详细的分析。

Metal-impregnating, a newly developed technology for surface treatment of cold drawing die of seamless steel pipes, is described, the process and conditions for metal-impregnating are discussed, and the analysis of the carbide layer forming on the surface of die is also given.
