新日铁室兰新2号高炉是在拆除原有2、3号高炉后建设的,以其代替1号高炉,于1985年7月18日开炉投产。投产以来操作一直都很顺利,在开炉后第27天利用系数达到了2.0的水平,以后一直生产稳定。1.2号高炉建设的基本指导思想充分利用原有设备以压缩设备费用,设计时主要着眼于与节能、省力、降低成本等增强设备能力有关的项目。其设备的基本特征是:采用布料均匀的串罐式无钟炉顶、激光式料面仪、垂直探测器、大型计算机等技
The new Nippon Chamberlain No.2 blast furnace was built after the removal of the existing No.2 and No.3 blast furnaces and was put into operation on July 18, 1985, replacing the No. 1 blast furnace. The operation has been going smoothly since it was put into operation, with a utilization factor of 2.0 on the 27th day after being opened, and has been producing steadily since. The basic guiding ideology for the construction of No.1.2 blast furnace makes full use of the original equipment to reduce the equipment cost. The design mainly focuses on the projects related to the enhancement of equipment capability such as energy saving, labor saving and cost reduction. The basic features of its equipment are: the use of uniform cloth-type bell-type bell-top, laser-type surface analyzer, vertical detectors, large computers and other technologies
