我国200米~3以上的高炉有100座左右,其中500米~3以上的有40余座,其装备水平普遍较低,炉顶设备大多数是双钟单室型。为了提高炉顶压力,延长大钟寿命,少花钱就能提高经济效益,将其中条件好的,改为双钟双阀炉顶是很有必要的。而解决好浮动密封问题也是设计的一大关键。据参考文献[1]、[2]介绍,于1974年8月在顿涅茨冶金工厂1033米~3高炉上安装
There are about 100 blast furnaces with 200m ~ 3 in our country, among which there are more than 40 blast furnaces with 500m ~ 3m and the equipment level is generally low. Most of the top equipment is double-bell single-chamber type. In order to improve the pressure on the roof, to extend the life of the clock, less cost will be able to improve economic efficiency, which will be good conditions, to double bell roof is necessary. And solve the problem of floating seal is also a key design. According to references [1], [2] Introduction, in August 1974 in the Donets Metallurgical Factory 1033 m ~ 3 blast furnace installed
