一、前言神户钢铁公司加古川烧结厂有两台球团烧结机和一台带式烧结机。球团矿在高炉炉料中占很大比例。在完成了旨在改善烧结球团矿质量的研究后,该厂大力开发提高烧结矿产量的生产技术,以便使生产能力有限的设备获得最高产量。结果,1985年12月烧结矿的利用系数达到世界最高水平,为2.2吨/米~2·时,而投产时只有1.5吨/米~2·时。下面就该厂采用的高产技术作一介绍。二、提高生产能力的技术改造表1给出了加古川烧结厂的主要参数。该厂的带式烧结机于1972年10月投产,而后进行了许多旨在改善生产能力的工作,重点放在改善烧结料层的透气性、提高焦炭的燃烧速度和烧结速度等方面,其中效果最佳的改造项目如下。为了提高烧结料层的透气性,增大了混合料的平均粒度,以降低返矿率甚至消除返矿;同时对需烧结成成球粒子的不纯矿石也增大了粒度并且优化了混合料的粒度,添加 I. Introduction Kobe Steel Corporation Kakogawa sintering plant has two pellets sintering machine and a belt sintering machine. Pellets account for a large proportion of blast furnace charge. After completing a study to improve the quality of sinter pellets, the plant focused on developing production techniques to increase the production of sinter so as to obtain the highest throughput of equipment with limited capacity. As a result, the utilization factor for sinter in December 1985 reached the highest level in the world, at 2.2 tons / m 2 · h and only 1.5 tons / m 2 · h at the time of commissioning. The following high-yielding technology used in the plant for an introduction. Second, to improve production capacity of the technical transformation Table 1 gives the main parameters of Kakogawa sintering plant. The factory’s belt sintering machine was put into operation in October 1972, and many work was done to improve the production capacity. The focus was on improving the air permeability of the sintering bed, improving the burning rate and sintering speed of the coke, and the effect The best transformation project is as follows. In order to improve the permeability of the sintering material layer, the average particle size of the mixture is increased to reduce the rate of remelting and even to eliminate the backmilling; meanwhile, the particle size of the impure ore to be sintered into spherical particles is also increased and the mixture is optimized The granularity, add
