宝钢热轧带钢生产技术进步与展望

Review and Prospect of Hot Strip Rolling Technology at Baosteel

系统地总结了自1989年宝钢2050mm热轧投产以来,宝钢热轧带钢产量提升、工艺技术应用、产品开发、质量改进的历程。从1989年到2007年,通过18年的努力,宝钢热轧技术从无到有,发展到拥有5条热轧宽带钢生产线、年产1980万t热轧钢卷的规模;热轧工艺技术水平、产品种类及等级、主要质量及技术经济指标等都分别达到了国内领先或世界一流水平。随着新的热轧生产线的建成投产,到2010年,宝钢热轧钢卷的生产能力将超过3000万t,并进一步拓展到取向硅钢、合金板带等产品的热轧生产技术领域。

The history of the capacity expansion of hot-rolled strip, the application of process technologies, the development of hot-rolled product, and the improvement of product quality since the commissioning of 2050mm hot strip mill in 1989 ,were systematically reviewed. With the development in the past 18 years from 1989 to 2007, Baost- eel has constructed five hot strip mills with a total annual capacity of 19.8 million tons, and the process technology application, product categories and steel grades, product quality, major technical and economical indexes, etc. , have been ahead of the domestic equivalent or reached the world advanced level. By the end of 2010, with more hot strip mills being put into operation, the expected total annual capacity will be over 30 million tons, and the product category will cover grain oriented （GO） Si-steels and alloyed steel strip and sheet.
