改善薄钢板表面粗糙性的新工艺比利时冶金工作者研究成功一种可给冷轧薄钢板以更大粗糙度从而改善其深冲性能的新工艺。该工艺的原理是用激光脉冲在光轧辊表面上蚀刻出网纹。一台二氧化碳激光器提供功率可调的连续激光束，激光束射向轧辊表面并由光学系统聚焦，而另一机械... New Process to Improve Surface Roughness of Sheet Steel Belgian metallurgical workers have succeeded in finding a new process that will give cold rolled sheet with greater roughness to improve its deep draw properties. The principle of the process is to use a laser pulse to etch the web on the surface of the light roll. A carbon dioxide laser provides a continuously adjustable power laser beam that is directed toward the roll surface and focused by the optical system while the other ...
