【摘要】 基于珠钢采用Nb微合金化技术成功地开发了管线钢X52和X56的事实,结合CSP薄板坯连铸工艺特点,探索出了一套适合含Nb钢薄板坯连铸的浇注温度制度、结晶器保护渣、连铸拉速和结晶器热流密度匹配及二次冷却曲线等工艺控制技术。更多还原

【Abstract】 Based on the fact that ZIS succeed in manufacturing X52 and X56 pipe line steel by means of Nb Micro-alloying technology,this paper combined with the technical characteristic of TSCR and investigated a series of technology to control thin slab continuous casting for Nb-bearing steel,such as the schedules of the casting temperature、mold casting powder、matching between castlng speed and heat flux density and cecondary coding wateretc.更多还原
