在热轧机上,原料(钢坯)加热后,钢坯表面会不可避免地产生氧化铁皮。氧化铁皮的害处是:1.增加轧辊的损耗;2.由于尺寸偏差和轧制精度而影响成品的质量。高压水除鳞是一种有效而经济的方法。
In the hot rolling mill, the raw material (steel billet) heating, the billet surface will inevitably produce scale. The harmful effects of scale are: 1. Increasing the loss of the roll; 2. Affecting the quality of the finished product due to dimensional deviation and rolling accuracy. High-pressure water descaling is an effective and economical method.
