挤压法为目前生产无缝钢管较先进的方法,这种方法不仅可以挤压小直径薄壁无缝钢管(直径大的不大适宜)而且也能生产不同几何形状的型钢。在生产中提高模具寿命和防止钢坯加热的氧化已成为挤压钢管和其他型钢的关键。但据已有资料介绍用玻璃(普通碎玻璃)做润滑剂,为挤压关键问题指出了解决的方向。我厂工程技术人员在伟大的整风运动中,解放了思
Extrusion method for the current more advanced production of seamless steel pipe method, this method can not only squeeze small-diameter thin-walled seamless steel pipe (large diameter is not suitable) but also can produce different geometries of steel. The key to increasing the die life and preventing billet heating during production has become the key to extruding steel tubes and other sections. However, according to the information available, glass (common broken glass) is used as a lubricant, which points out the solution direction for pressing the key problems. I plant engineering and technical personnel in the great rectification campaign, liberation of thinking
