不锈钢在轧制、热处理等加工过程中,金属表面生成一层致密而牢固的氧化皮。因此板坯在进一步轧制时,为了避免氧化皮压入金属及磨损轧辊;为了提高冷轧成品的精加工及改善表面质量,以进一步改善不锈钢的耐蚀性,必须把氧化皮去除。不锈钢氧化皮的去除,是比较复杂的工艺之一,经常由于热轧或热处理后缺乏可靠的清除氧化皮的方法和熟练的操作而使不锈钢板的生产不能顺利地进行或大量报废。近几年来,国内外的冶金工作者对不锈钢的酸洗方法
Stainless steel In rolling, heat treatment and other processing, the metal surface to generate a dense and strong oxide scale. So in the further rolling slab, in order to prevent the pressure of the metal into the metal and wear roller; In order to improve the finished cold-rolled finished and improve the surface quality, in order to further improve the corrosion resistance of stainless steel, the oxide scale must be removed. The removal of stainless steel oxide scale is one of the more complicated processes. The stainless steel plate production can not be carried out smoothly or scrapped frequently due to the lack of reliable scavenging method and skilled operation after hot rolling or heat treatment. In recent years, metallurgical workers at home and abroad on the stainless steel pickling method
