随着科学技术的发展,对钢材产品的质量和表面形状的要求越来越严格。在优质钢,特别是特殊钢的现代生产中,用最经济最有效的方法去除钢坯的各种表面缺陷和氧化铁皮,以保证钢材的最终质量,已成为重要的工序之一。钢坯砂磨就是一种最经济最有效的方法,在我国,尤其在世界各主要工业国都在采用。 With the development of science and technology, the requirements on the quality and surface shape of steel products have become more and more strict. In the modern production of high-quality steel, especially special steel, it has become one of the most important processes to remove various surface defects and scale of billet by the most economical and effective method to ensure the final quality of steel. Slab sanding is one of the most economical and effective methods, and is being adopted in our country, especially in all the major industrial countries in the world.
