河北省中型高炉热风炉绝大多数是旧式内燃热风炉。虽经近几年的技术改造,取得一定效果,风温有所提高。如81年单炉最高风温为1056℃,全省平均达到960.C℃。但与“六五规划”要求的1100℃风温目标仍有较大距离。旧式内燃热风炉由于在结构上存在许多缺陷,进行技术改造已是势在必行。下面仪对改造中的一些问题谈几点看法。
Medium-sized blast furnace blast furnace in Hebei Province is the vast majority of old-style internal combustion stove. Although the technological transformation in recent years, achieved some results, the temperature has increased. Such as 81 years, the highest single-oven temperature of 1056 ℃, the province an average of 960. C ℃. However, there is still a long way to go for the target of 1100 ℃ air temperature required by the “Sixth Five-Year Plan”. Because of the many defects in the structure of the old internal combustion hot stove, it is imperative to carry out technological transformation. The following instrument on the transformation of some of the questions to talk about.
