攀钢炼铁厂从70年投产以来,风温较长时期维持在900～950℃之间。78年11月在2~＃高炉热风炉试烧混合煤气,焦炉煤气配比为4.76％,风温提高50℃。但由于混合方式不好,一段时间以后发现耐火砖局部过熔,热风炉内发生小爆震引起掉砖,此外混合煤气能量也未充分利用,故未在其他高炉推广。 Panzhihua Iron and Steel Works from 70 years since its inception, the longer the temperature maintained at between 900 ~ 950 ℃. 78 November in 2 ~ # blast furnace hot mix test gas, coke oven gas ratio was 4.76%, the air temperature increased by 50 ℃. However, due to the poor mixing method, refractory bricks were partially melted over a period of time, and a small explosion occurred in the hot blast stove to cause the bricks to fall off. In addition, the energy of the mixed gas was not fully utilized and was not promoted in other blast furnaces.
