连铸连轧的金属学特点及其生产应用途径

PHYSICAL METALLURGY AND PRODUCTION APPLICATIONS OF DIRECT CONNECTION OF CONTINUOUS CASTING-HOT ROLLING TECHNOLOGY

阐述了连铸连轧的基本方式及其金属学特点。分析了连铸连轧与普通热轧工艺在产品组织和力学性能方面产生差异的原因。根据对不同钢种要求的大学性能，指出了连铸连轧的生产应用途径。

The principal processes and physical metallurgy of direct connection of continuous cast-ing-hot rolling technology is reviewed.A comparison is made between the direct connection of con-tinuous casting-hot rolling and conventional hot rolling technology so as to investigate the reasons that cause differences in product micro-structure and mechamical properties.The production applications of the direct connection of continuous casting-hot rolling technology are proposed depend-ing on different grades with different properties.
