七十年代初氧气底吹转炉技术的应用,使人们看清了氧气顶吹法尚有喷溅大,熔池搅拌不充分使反应离平衡较远,金属收得率较低,冶炼品种有限等缺点,为继续发挥现有大型氧气顶吹转炉的优势,冶金工作者仿照底吹法在LD转炉底部增加底吹装置,其优点克服了顶吹法的缺点,经过近十年的实践,证明是行之有效的。 The application of oxygen bottom blowing converter technology in the early seventies made people see that the oxygen top-blown method is still big splashing, the molten pool is not fully stirred to make the reaction far away from balance, the metal recovery rate is low, the smelting variety is limited Shortcomings, in order to continue to play the advantages of the existing large-scale oxygen top blown converter, metallurgical workers imitate bottom blowing method in the bottom of the LD converter to increase the bottom blowing device, its advantages overcome the shortcomings of the top-blowing method, after nearly a decade of practice, proved to be effective.
