前言神户钢铁公司加古川钢铁厂的高炉炉料准备工序包括一座烧结厂和两座球团厂,高炉操作的特点是球团配比高。因此,在高炉投产初期,因炉内透气性差,操作指标不佳。为了解决这一问题,对球团采取了改善高温特性的措施,对烧结矿则研究了增加产量的工艺技术。结果,1984年烧结厂(有效面积262米~2烧结机一台)月平均利用系数达到2.15吨/(米~2·时),为日本最高水平。一、研究开发经过烧结矿增产技术的研究开发前后分为三个阶段:①利用本公司既有球团厂又有烧结厂这一有利条件,通过增大烧结厂混合料中粗粒原料的配比等来改善透气性;②据根高
Foreword The blast furnace charge preparation process at Kakogawa Steel Works, Kobe Steel Company, consists of a sinter plant and two pellet plants. The operation of the blast furnace is characterized by a high proportion of pellets. Therefore, the early blast furnace put into operation, due to poor gas permeability furnace, poor performance indicators. In order to solve this problem, the pellets have taken measures to improve the high-temperature characteristics, and sinter has been studied to increase production technology. As a result, the average utilization coefficient of sinter plant (effective area of 262 m ~ 2 sinter) reached 2.15 tons / (m ~ 2 · h) in 1984, the highest level in Japan. First, the research and development After sinter production technology research and development before and after the divided into three stages: ① the company’s existing pellet plant and sintering plant this favorable conditions, by increasing the sintering plant mixture of coarse raw materials with Than to improve air permeability; ② According to root height
