78年以前,我厂使用的管式热风炉,风温只有500℃左右。同年12月,结合高炉改造,改造了管式热风炉,推行了球式热风炉和布袋除尘器的新工艺新技术。79年平均风温使用到1050℃,80年1～6月又使用到1.100℃,最高用过1.150℃。强化了高炉冶炼,促进了优质、高产、低耗的进一步实现,并为下一步推广喷吹技术创造了条件。为了更好地发挥球式热风炉的作用和正确运用高风温,我们作了以下工 78 years ago, I use the tube furnace stove, the air temperature is only about 500 ℃. In December the same year, combined with the blast furnace transformation, transformation of the tube stove, the implementation of the ball stove and bag filter new technology new technology. 79 years, the average temperature to 1050 ℃, 80 years from January to June and used to 1.100 ℃, the highest used 1.150 ℃. Strengthen the blast furnace smelting, and promote the high quality, high yield, low-cost further to achieve, and for the next step to promote the injection technology to create the conditions. In order to better play the role of the ball stove and the proper use of high winds, we made the following
