转炉维修的任务和问题。其中包括耐火衬、耳轴、托圈、轴承及传动装置,并考虑了结构的发展。除了平炉和电炉的炉膛精炼法和贝塞麦和托马斯转炉的鼓风炼钢法以外,1952年在奥地利林茨的联合钢铁公司投产了LD炼钢设备,从而提出了一种新方法——LD法。比较贝塞麦和托马斯转炉和LD转炉的炉容增长速度可以看出,LD法的进展速度是极为惊人的。从贝塞麦转炉第一次试验采用的100公斤容量的炉体增长到70吨,共经历了半个多世纪。而LD转炉从1952年的30吨增长到300吨仅用了12年。除了固定式设备外还产生了可更换式设备。这样急剧的发展速度对设计和维修也带来了新问题。
Converter repair tasks and problems. Including refractory lining, trunnion, bearing ring, bearings and transmission, and taking into account the development of the structure. In addition to the hearth and hearth furnace refining method and Bessemer and Thomas converter blast steelmaking method, the United Steelworks in Linz, Austria, in 1952 put into operation LD steelmaking equipment, which proposed a new method - LD law. Comparing the furnace capacity growth rate of Bessemer and Thomas converter and LD converter can be seen, LD method of progress is extremely alarming. From a 100 kg capacity furnace used in the first test of the Bessemer converter to 70 tons, it took more than half a century. The LD converter increased from 30 tons in 1952 to 300 tons in only 12 years. In addition to fixed equipment also produced a replaceable equipment. Such a rapid pace of development also poses new problems in design and maintenance.
