SWRCH35K冷镦钢的研制

Development of SWRCH35K Cold Heading Steel

为丰富产品种类,满足市场需求,对SWRCH35K冷镦钢进行了研制。根据SWRCH35K冷镦钢的特点,首先制定了企业生产标准,确定合理的生产工艺流程,然后严格控制转炉冶炼、LF精炼、连铸、轧制各工艺环节,试制生产出了SWRCH35K冷镦钢产品。通过对产品性能进行检测和分析,结果显示其化学成分、力学性能和冷顶锻测试等均符合8.8级紧固件生产要求。

In order to enrich the product range and meet the market demand,SWRCH35K was developed.According to the characteristics of SWRCH35K,firstly,the enterprise production standard was established,the reasonable production process flow was determined,and then the converter smelting,LF refining,continuous casting,and rolling were strictly controlled.The SWRCH35K products were trialproduced.Through testing and analysis of product performance,the results show that the chemical composition,mechanical properties,and cold upsetting test all meet the requirements of grade 8.8 fastener production.
