由于工业技术的发展,对各种钢材表面质量的要求越来越严格,因此钢材(包括成品和原料)的清理技术和设备相应地得到了突飞猛进的发展。但对于许多一般用途和非十分重要用途的钢材要求不那么严格,即使重要用途的钢材,如钢丝绳……也不可能一点缺陷也没有,这就是 Due to the development of industrial technology, the requirements on the surface quality of various steels have become more and more stringent. Therefore, the technologies and equipment for cleaning steel products (including finished products and raw materials) have been developed by leaps and bounds accordingly. However, the requirements of many general-purpose and non-critical-use steels are less stringent, and even important-purpose steels such as wire ropes ... are unlikely to be defective at all, that is
