|
Abstract:
介绍了采用氧气顶底复吹转炉及LF精炼和VD工艺，利用连铸板坯浇注，轧钢环节采用HY-TMCP工艺生产Q390DZ35高强高抗层状撕裂钢板。通过对化学成分模拟计算，制定适合本公司的冶炼、连铸、轧制工艺，利用微合金化和HY-TMCP技术，成功开发了Q390DZ35高强Z向钢，产品质量满足GB/T1591-2018及GB/T5313-2014要求。
The production process of Q390DZ35 high strength and thick drawing with oxygen top-bottom combined blowing converter, LF furnace refining, slab continuous casting and TMCP is introduced. Through rational design of chemical composition and formulation of smelting, continuous casting and rolling processes suitable for our plant, Q390DZ35 high strength Z-directional steel was suc-cessfully developed by combining microalloying with TMCP technology. The product quality meets the requirements of GB/T1591-2018.
