摘　　要：介绍了国产弹簧钢丝热处理生产线的现状和发展。目前国产弹簧钢丝生产线大多采用油淬火回火工艺,钢丝直径大于8 mm时,设计产能1 t/h。“高速”弹簧钢丝生产线采用“水淬火”工艺,对于直径大于8 mm的钢丝,生产线设计产能2.5 t/h。以直径10 mm 55SiCr弹簧钢丝为例,对热处理后钢丝性能和金相组织进行了分析。对未来弹簧钢丝生产线的设计理念进行了展望。To introduce evelopment and current situation of domestic heat treatment line of spring wire.At present,most of domestic spring wire production lines adopt oil quenching and tempering process,when steel wire diameter is larger than 8 mm,design capacity is about 1 t/h.High speed spring wire production line adopts water quenching process,for diameter of steel wire larger than 8 mm,production line design capacity is about 2.5 t/h.Taking diameter 10 mm 55SiCr spring wire as example,properties and microstructure of steel wire after heat treatment were analyzed.The design concept of spring wire production line in future is prospected.
