摘要
通过对控冷工艺进行分析 ,研究了不同冷却速度对ML35CrMo冷镦钢盘条组织性能的影响。结果表明 :当吐丝温度为 85 0℃、冷速为 0 .83℃ /s时 ,金相组织为珠光体 +铁素体 ,晶粒度 8～ 9级 ,脱碳层 (0 .2～ 0 .5 )D % 。
To research the effect of different cooling speed on the microstructure and property of ML35CrMo cold heading steel wire rod by means of cooling-controlled process analysis. The result shows that the microstructures are pearlite and ferrite, the grain size is grade 8～9, the decarburization coat is (0.2～0.5) D % when the wire rod exit temperature is 850 ℃ and the speed of cooling is 0.83 ℃/s. The mechanical and cold heading property of the wire rod are good.
