生产特重钢轨首先必须考虑孔型系统的基本工艺条件。合理的重轨孔型系统的轧制道次不应少于9道次。在现有条件下不增建轧机是不可能大量生产特重钢轨的。增建一座850二辊可逆式荒轧机可能是适宜的。这样必须拆除现有1,2号加热炉,增建一座步进式加热炉。精整区也应相应改造,如矫直机、铣床等都要采取相应措施。 Special heavy rail production must first consider the basic conditions of the hole system. Reasonable heavy rail pass system rolling pass should not be less than 9 times. Under the existing conditions it is impossible to mass produce extra heavy rails without building additional rolling mills. An additional 850 two-roll reversible mill may be suitable. In this way, the existing heating furnaces No. 1 and No. 2 must be removed and a step furnace built. Finishing area should be adapted accordingly, such as straightening machines, milling machines, etc. must take appropriate measures.
