前言武钢初轧厂均热炉原系苏修设计的炉底中心烧嘴均热炉。随着生产的发展暴露出许多问题,为此于1970年开始改炉底中心供热为上部四烧嘴多点供热。改造后炉子的热工性能、产量和烧钢质量均有一定的提高和改善,维护和操作的劳动条件也大为改善。然而对于换热田管砖易堵、空气漏损严重的问题在改造中一直未有突破,曾经作过大风机和改进换热室砌筑等方面的试验,效果都不大明显。因此炉坑寿命短,一般为二年左右,且“青壮期”短,热负荷衰减快。这直接影响着炉坑能力的进一步发挥,成了初轧厂生产环节中卡脖子的地方。为了改变这种被动局面,以适应高速度
Preface Wuhan Iron and Steel Plant were the original hot rolling furnace Su original design of the hearth hearth furnace are soaking furnace. With the development of production exposing a lot of problems, for the beginning of 1970 to change the bottom center heating for the upper four burner multi-point heating. After the renovation of the furnace thermal performance, yield and quality of steel have a certain increase and improvement, maintenance and operation of labor conditions have also been greatly improved. However, for the heat transfer pipe tile easy to block, the problem of serious air leakage damage in the transformation has not been a breakthrough, once made a big fan and improve the heat exchange chamber masonry and other aspects of the test, the effect is not obvious. Therefore, pit life short, usually about two years, and “young” short, fast decay heat load. This has a direct impact on the further development of the furnace pit capacity and has become a staple in the production chain of the early rolling mill. In order to change this passive situation, to adapt to high speed
