吴德炳发明的高硫合金钢最近又有新突破。据天津天钢集团公司第二炼钢厂使用情况表明 :高硫合金钢滚动轴承性能优于当今在世界占霸主地位的瑞典ＳＫＦ新近研制的Ｅｘｐｌｏｒｅｒ球面滚子轴承。长期以来 ,瑞典轴承称霸世界 ,其价格高于我国及其他国家同类型号轴承的 8～ 10倍。
Wu Debing invented high-sulfur alloy steel has a new breakthrough recently. According to Tianjin Tiangang Group’s second steel mill usage shows: high-sulfur alloy steel rolling bearing performance superior to today’s dominant player in the world of Sweden’s SKF Explorer spherical roller bearings recently developed. For a long time, Swedish bearings dominate the world, the price is higher than the same type of bearings in our country and other countries 8 to 10 times.
