自从高炉操作改为高压以来,炉顶装料设备在使用中最难解决的问题,第一是漏;第二是由于漏而引起的设备的磨捐问题。在高炉使用粉末较多的热烧结矿的情况下,混有微小颗粒的高压气流在漏气处对设备的磨损是相当惊人的。因此,对高压炉顶设备的密封问题应给予足够的注意。一、料缶式高炉小钟拉杆的密封鞍钢某高炉在炉顶压力提高到0.8公斤/厘米~2时,拉杆的使用寿命仅有三、四个月,至多半年,在使用期间需
The most difficult problem in the use of top loading equipment since the operation of the blast furnace was changed to high pressure, the first is leakage; the second is the problem of abrasion of equipment due to leakage. In the case of blast furnace using hot sinter with more powder, the high-pressure air flow mixed with fine particles is quite astonishing to the wear of the equipment on the air leak. Therefore, adequate attention should be paid to the sealing of high-pressure top equipment. A material blast furnace bell bellows seal Anshan Iron and Steel blast furnace pressure in the roof to 0.8 kg / cm ~ 2, the lifespan of the rod only three or four months, up to six months, during use
