冷却工艺对70kg级高强钢组织性能影响分析

Effect of cooling process on microstructure and properties of 70 high strength steel

在相同的成分配比及轧制工艺条件下,对70kg级试验钢进行不同冷却工艺的生产试验,通过轧后钢板金相组织及性能数据结果,研究终冷温度及冷却速率对钢材组织及性能的影响,通过调整控冷工艺实现试验钢板强度及塑性的最佳匹配,确立了批量生产70kg级高强钢的控轧控冷工艺参数。

In same of components ratio and the rolling process conditions Xia, on 70kg level test steel for different cooling process of production test, through rolling Hou plate metallographic organization and the performance data results, research end cold temperature and the cooling rate on steel organization and the performance of effect, through adjustment control cold process achieved test plate strength and the plastic of best match, established has production 70kg level high strength steel of control rolling control cold process parameter.
