金属热切圆锯片的激光处理

Laser treatment of law blade

摘要: 型钢生产线上现使用的锯片裂纹、崩齿现象比较严重,导致锯片提前下线报废;同时由于锯片是一个面积较大的薄板,其厚度与直径的比非常小,且又是在高速旋转及高速送进的条件下工作,因此,在锯切时存在着严重的振动问题。针对莱钢中型厂热切圆锯片存在的问题,对锯片齿尖和基体采用激光处理。经实验研究发现,锯片经激光处理后,锯齿的硬度、耐磨性得到提高,整个锯片的振动特性和整体稳定性得到改善,故锯片的使用寿命和锯切质量能够很好地保证。

Abstract: Aiming at the exist problem of saw blade made in Laiwu Steel and Iron Co.saw blade treated by laser was studied in the paper.The result proved that the hardness and anti-abrasion of the saw teeth are increased,the vibration and stability of the saw blade were improved which were heat-treated by laser,so the longevity of saw and quality of sawing can be ensured easily.
