汽车轻量化发展伴随着汽车弹簧使用强度的提高，从而对钢中夹杂物的要求也越高。通过分析典型的汽车弹簧对线材中夹杂物的要求，介绍了国外弹簧钢线材先进生产企业的冶炼工艺，综述了目前国内外关于弹簧钢中夹杂物的研究报道，可为国内弹簧钢线材生产企业开发或改进汽车用弹簧钢线材提供参考。
Corresponding to the development of lightweight car, the design strength of automobile springs goes up higher and higher. The higher the design strength of spring is, the stricter the inclusion requirements for spring steel will be. The cleanness requirements of spring steel wire rod used for automobile springs were analyzed, and then the smelting process in manufacturing spring steel wire rod of advanced enterprises abroad was introduced, and ifnally the research reports about non-metallic inclusions in spring steel at home and abroad were reviewed. It aims at providing references for domestic enterprises to develop or improve spring steel wire rod for automobile springs.
