分析钢管冷切锯与热锯切的不同之处

       分析钢管冷切锯与热锯切的不同之处?一般以被切轧件的温度定义锯切类型,有以下几种类型:
       1、轧件温度低100℃时为冷切。
       2、轧件温度在100~600℃时为温切。
       3、轧件温度高于600℃时为热切。
       一般波球体育直播将用于锯切轧件温度低于300℃的金属锯机称之为钢管冷切锯,将用于锯切轧件温度高于600℃的金属锯机称之为热锯。热锯和冷锯,其设备结构是没有区别的。
       对于方钢、圆钢生产线,由于钢管冷切锯切时钢材太硬,锯切面积大,锯切周期长,切口质量低,所以一般很少采用钢管冷切锯,大多采用热锯切或采用砂轮锯机。对于工槽角、钢管等生产线,由于其为薄壁结构,单位时间内锯切面积小,热切容易使钢材变形,且飞边严重,所以基本上都采用钢管冷切锯
