前言纯氧顶吹转炉炼钢是近年来世界上发展得比较快的一门先进技术。由于它具有各方面的优点,对提高钢产量方面有很大潜力。因此,近年来国内也大力发展了中小型的纯氧顶吹转炉炼钢。在1965年又开始设计、制造了大型的120吨纯氧顶吹转炉炼钢整套设备,而转炉的炉壳和托圈是整套炼钢设备的关键。搞这样大型的设备,采用怎样的结构形式才比较合理?对这一类问题,我们只有按照毛主席关于“一个正确的认识,往往需要由物质到精神,由精神到物质,即由实践到认识,由认识到实践这样多次的反复,才能够
Preface Pure oxygen top-blown converter steelmaking is an advanced technology developed relatively fast in the world in recent years. Because of its various advantages, it has great potential for increasing steel production. Therefore, in recent years, the domestic also vigorously develop small and medium sized pure oxygen top-blown converter steelmaking. In 1965, it started to design and manufacture a large-scale 120-ton pure oxygen top-blown converter steelmaking complete plant. The furnace shell and the support ring of the converter are the key to the whole steelmaking equipment. It is only reasonable to engage in such a large-scale equipment and what kind of structural form is used. Only on the basis of Chairman Mao’s principle of "a correct understanding, we often need to change from materialism to materialism to materialism, from practice to understanding It is only by recognizing that there are so many repetitions of practice
