俄罗斯的轧钢车间里现在约有 2 40座连续加热炉在使用。 60年代末以前建的是结构简单、造价相对低廉的推钢式炉。当它们不再能满足轧钢生产要求时便开始过渡到步进底式炉(小型和线材厂 )和步进梁式炉 (轧板厂 ) ,后者虽然结构复杂还贵一些 ,但是克服了推钢式炉的缺点。70年代末 There are currently about 240 40 continuous furnaces in the Russian rolling mill. Built by the end of the 1960s was a pusher-type furnace with a simple structure and relatively low cost. When they no longer meet the rolling production requirements, they began to transition to step-bottom furnaces (small and wire mill) and walking-beam furnaces (mill), which, although complex and expensive, overcomes the problem of pushing steel Shortcomings of the furnace.
