人们在高炉①炉身上部,将从内炉壁②伸出的环状突出部③和(13)按上、下两方向隔开,并配置对称的混合层形成板④。由于发明者将混合层形成板环状突出部(13)前面至凹部底面距离 A 和突出部(13)间距离 C 定在不小于装入物最大粒子径,并且又把其最上层至最低层之间的高度定在装物时矿石层⑤、焦炭层⑥厚度的平均值以上,所以装入物便可随着它的下降而被搅乱,进而形成矿石、焦炭混合层⑦。鉴于该混合层具有迅速形成气体流速领域的特点,因此可防止内炉壁②粘着物的生成和稳定炉况。
In the upper part of the blast furnace ①, people arrange annular symmetrical mixing layer forming plates ④ with annular projections ③ and (13) extending from the inner furnace wall ② in the upward and downward directions. Since the inventors set the distance C from the front of the mixed layer forming plate annular projection (13) to the bottom of the recess A and the distance C between the projections (13) to not less than the maximum particle diameter of the insert and turn the uppermost layer to the lowermost layer The height between the ore layer ⑤ ⑤, the coke layer ⑥ thickness of the average value above, so the load can be as it fell and was disturbed, and thus the formation of ore, coke mixed layer ⑦. In view of the fact that the mixed layer has the characteristic of rapidly forming a gas flow rate, it is possible to prevent the generation of sticking material and the stable furnace condition of the inner wall 2.
