摘　　要：介绍用于生产10.9级高强度标准件的Φ6.5mm10B21冷镦钢盘条的生产工艺。通过在冶炼过程中严格控制钢中N和O的含量,稳定B的吸收率,提高淬透性;在精炼过程中全程控铝,一次喂线;连铸过程中过热度偏高20～30℃,提高铸坯质量;以及轧制过程中采用冷速为0.3～1℃/s的控冷工艺,加热温度950～1000℃,吐丝温度850～860℃,用高线机组成功生产出合格的10B21冷镦钢盘条,产品各项指标满足要求。To introduce the production process of diameter 6.5 mm 10B21 cold heading steel wire rod for producing 10.9 grade high strength standard part. To strictly control the content of N and O in steel smelting process, to stabilize the absorptivity of B, to improve hardenability, to control aluminum in all process and one time feeding wire in refining process, to raise the superheat 20 - 30℃ higher than normal in continuous casting process to improve casting billet quality, to adopt control cooling process of 0.3 - 1℃/s, heating temperature 950 - 1 000℃, wire rod laying at 850 - 860℃ in rolling process, qualified 10B21 cold heading steel wire rod is produced successfully in high speed wire rod mill, and each indexes of products reach requirements.
