油淬火-回火弹簧钢丝生产技术现状及发展方向

油淬火-回火弹簧钢丝是生产制造轿车悬挂弹簧和发动机气门弹簧的原料,这两类弹簧在汽车工业零部件中属于"D"级产品,即按相关规定,一旦发现有缺陷整车必须强制召回.所以,对该用途的钢丝有着极高的可靠性和安全性要求.油淬火-回火弹簧钢丝和汽车轮胎用钢帘线并称为钢丝制品的顶级产品.文章介绍了油淬火-回火弹簧钢丝的常用钢种,以及国外的钢种开发、生产技术关键及发展趋势,同时也介绍了目前国内技术水平和生产状况,并提出了改进措施和发展方向.

Oil Tempered Wire's Present Production Situation and Development Trend

Oil quenched and tempered spring wire is the raw material of car's suspension spring and valve spring. The two kinds of springs belong to the key spare parts of the auto industry. Once there is any defect with these spare parts,the car has to be recalled forcibly. So the wire must be very reliable and safe. The common grades of this oil tempered spring wire are introduced, together with the introduction to the development of this steel wire, key technologies in the production and its development trend abroad. Domestic technology and production situation of this steel wire is also described, together with the discussion on improvement and development trend of this steel.
