银川市砖瓦厂,1959年在一座新建的30门轮窑上,试用钢筋混凝土哈风闸代替铸铁闸的试验获得成功.这30套混凝土哈风闸,从1959年3月至冬季停火前,使用情况正常,效果良好,经停火后检查,混凝土哈风闸边部有些裂纹,但在停火前没有发现其他不正常的情况. 应用混凝土哈风闸,可以约节大量的生铁.轮窑的一个哈风闸,需要铸铁的数量一般在1.5-2吨.在这样一座较小的30门轮窑上就可以节约45-60吨的生
In Yinchuan brick and tile factory, on a new 30-wheel kiln built in 1959, the trial of a reinforced concrete haze damper instead of a cast iron gate was successful. The 30 sets of concrete sluice gates from March 1959 to the winter ceasefire, The condition of use was normal and the effect was good. After the inspection after the ceasefire, there were some cracks on the edge of the concrete damper, but no abnormal conditions were found before the ceasefire. Applying a concrete damper, it was possible to save a large amount of pig iron. One of the wheel kiln Harbin Gate, the quantity of cast iron is generally 1.5-2 tons. In such a small 30-door wheel kiln, 45-60 tons of life can be saved.
