唐山钢厂以往的化铁炉都采用在一边斜板上滑加料的装料设备、单风管切线式接入风箱的输风管道、二排风口、并且没用冷却水箱、因之经常发生炉料不平,一边铁多焦少,另一边铁少焦多;另外,进风带各部位的进风量也有多有少,相差很大。今年上半年,唐山钢厂新建了一个化铁炉,针对老化铁炉的主要缺点,在设计上采用了下列几项先进经验:
Tangshan Iron and Steel Furnace in the past are used in the side of the inclined plate ramp loading feeding equipment, single duct tangential access to the wind pipe duct, two vents, and no use of cooling water tank, which often occurs Burden uneven, while the iron less coke more iron less coke on the other side; In addition, into the wind with the various parts of the air volume is also more or less, a big difference. The first half of this year, Tangshan Iron and Steel built a new furnace, the main shortcomings of the aging furnace, in the design using the following several advanced experience:
