1.前言由于LD转炉的生产率很高而生产出的钢质量又好,因此得到了迅速发展。但是从金属-炉渣搅拌能力的观点来看,这种LD转炉工艺并不如Q—BOP工艺。日本钢管公司在其LD转炉早期发展阶段就注意了这个问题,该公司开发了两种技术:一种是LD—CL(LD转炉使用回转氧枪)技术。使氧枪产生回转运动,用以形成回转火点来加强渣-钢之间的搅拌和成渣过程。开始用于80t转炉,现在已经正式用于
1. Introduction Rapid development has been achieved due to the high quality of the steel produced by LD converter’s high productivity. However, this LD converter process is not as good as the Q-BOP process from a metal-slag mixing standpoint. Nippon Steel Corporation paid attention to this issue during its early stages of LD converter development. The company has developed two technologies: one is LD-CL (LD converter using rotary lance) technology. So that the oxygen gun rotary motion to form a rotary ignition point to strengthen the slag - steel mixing and slagging process. Started for 80t converter, now officially used
