濮阳市水冶钢铁厂2号高炉原为28m~3,于1987年扩容为50m~3,但热风炉没有改造,风温只有550～600℃,因此焦比高,成本高,产量低,亏损严重,被迫于1990年1月停炉,对热风炉进行改造.通过多方案比较,最后决定建造ZSD型热风炉. ZSD型热风炉是一种新型高温热风炉(已取得两项发明专利权),它具有如下特点:①在热风炉直径、蓄热室高度和格子砖
Puyang City Shuitui Steel Plant No. 2 blast furnace originally 28m ~ 3, expansion in 1987 to 50m ~ 3, but the stove has not been transformed, the temperature is only 550 ~ 600 ℃, so high coke ratio, high cost, low output, loss Serious, was forced to shut down in January 1990, the stove to transform.According to a multi-program comparison, the final decision to build ZSD-type stove.ZSD-type stove is a new type of high-temperature hot stove (has obtained two patents ), It has the following characteristics: ① in the stove diameter, regenerator height and the lattice brick
