近年来,在国外底吹氧气转炉有所发展,它是炼钢工业技术发展的新动向之一。据了解,国外采用底吹氧气转炉炼钢与顶吹氧气转炉比较,在钢的质量相同的条件下,还具有多用废钢百分之二十、金属收得率高、烟尘少等优点。尤其值得注意的是:采用底吹氧气转炉对于现有的平炉、底吹空气转炉和侧吹转炉的技术改造有着现实意义。底吹氧气转炉的厂房不象顶吹氧气转炉那样高,利用原有的平炉或底吹空气转炉的厂房、吊车等,很容易改为底吹氧气转炉,大大地节约了投资。
In recent years, foreign blowing oxygen converter has been developed, it is one of the new trends in the development of steel industry technology. It is understood that the bottom of the oxygen blowing at the end of the converter and the top blowing oxygen converter compared to the same quality of steel, but also has a multi-purpose scrap 20%, high metal recovery, less dust and so on. In particular, it is worth noting that the technological transformation of the bottom-blown oxygen converter to the existing open hearth, bottom-blown air converter and side-blown converter is of practical significance. Bottom blowing oxygen converter plant is not as high as the top blowing oxygen converter, the use of the original open hearth or bottom blowing air converter plant, cranes, etc., it is easy to change to the bottom blowing oxygen converter, greatly saving investment.
