1.前言高碳钢线材被拉制成钢丝,并且用它来生产例如弹簧、轮胎帘布、PC钢丝(预应力混凝土结构用钢丝)、悬置桥接电缆用电桥标准导线等产品。用户对这些高碳钢线材质量的要求已变得越来越严格。当线材在轧机内严格加工时,为了保证最终产品质量的“无缺陷”原材料供应,日本神户钢公司已努力改进各种生产技术和 1. Introduction High-carbon steel wire rod is drawn into steel wire and used to produce products such as springs, tire cord, PC steel wire (prestressed concrete structure steel wire), suspension bridge cable standard wire and other products. Users of these high-carbon steel wire rod quality requirements have become more stringent. When the wire is strictly processed in the rolling mill, Kobe Steel Co., Ltd. of Japan has made great efforts to improve various production techniques and to ensure the “non-defective” raw material supply of the final product quality
