摘要
基于对珠钢EAF—CSP流程Nb微合金化技术的系统研究，有效地解决了混晶问题，并利用Nb—Ti复合微合金化技术成功地开发了汽车用钢QStE340-460TM。分析结果表明，开发的含Nb—Ti钢带具有优异的韧性、冷成形性能和良好的焊接性能，完全满足汽车、半挂车用钢的要求。
Based on the systematical research d the Nb micro- alloying technology in EAF- CSP process,the effective measure was proposed to solute the mixed grain. Tne automobile plate QStE340-460TM was successfully developed by the Nb - Ti micro- alloying technology. The analysis indicated that the developed Nb- Ti micro- alloying plate has the outstanding toughness, the cold forming performance and the good welding performance, which completely satisfied with the request of automobile and semitrailer.
