摘要
介绍了通过采取熔氧结合、LF精炼及喂丝、软吹、保护浇铸和轧制合理控制冷却等措施,解决55CrMnA优质弹簧扁钢生产中存在的扁钢硬度高、表面毛刺、侧面裂纹等问题的实践经验。
The production piacfice was described, for which many effective measures such as catch carbon method, LF refining, wire feeding, protective casting and reasonable control cool system, etc. have adopted and the quality problems of the flat bars such as high hardness, surface barbs and cracks in the side in production of 55CrMnA high quality spring flats were solved.
