1.前言目前国外广泛采用盐酸、硫酸和其它酸液来消除线材和冷拔钢材表面的氧化铁皮。用化学方法清除氧化铁皮可以实现高速获得良好的表面酸洗质量,但也大量地消耗了酸液,损耗了金属基体,并污染水源及周围环境。因此近年来,世界各工业国正力图用机械除磷代替化学酸洗,并已取得显著成效。 1. Introduction At present, foreign widely used hydrochloric acid, sulfuric acid and other acids to eliminate the wire rod and the surface of the steel oxide scale. Chemical removal of the scale can achieve good surface pickling quality at high speeds, but also consumes a significant amount of acid, depletes the metal matrix, and contaminates the water and the surrounding environment. In recent years, therefore, various industrialized countries in the world are trying their best to replace chemical pickling with mechanical phosphorus removal and have achieved remarkable results.
