解惑冷锯切水喷淋面积过大及其处理

       解惑冷锯切水喷淋面积过大及其处理。
       圆钢在进入冷锯时在320℃左右,锯切、退锯过程中采用水淋洒冷却锯片,实际生产中水喷淋面积过大,造成钢表面质量下降,也浪费水。
       采取的处理措施:
       1、将原有的淋洒式水管改为喷淋式,增加喷嘴,采用雾状喷淋,对锯切点实行主要喷淋。由于喷嘴端面有圆弧凹面,可使水雾化,使喷洒均匀,且使用螺杆连接,易替换,利于维修工作。
       2、采用环绕冷却法冷却锯罩,对锯切口和锯切齿进行喷淋冷却,有针对性地冷却主要部位。
       3、在锯切进给时采用喷射阀,增加喷射压力,在退锯时关闭喷射阀。
