日本钢管公司福山钢铁厂通过改造现有5号烧结机,已开始生产烧成球团矿烧结块(HPS),年生产能力为6Mt。烧成球团矿烧结工艺的基本原理是大量使用细铁矿粉之类的球团原料,该工艺具有以下三个特点:1)用10台圆盘造球机强化造球作业,生产高质量的生球。2)生球外裹焦粉提高焦粉燃烧效率。3)用2台宽带输送机进行小心布料,防止生球破碎,烧成球团矿烧结法由于采用的原料便宜,还原性高,SiO_2含量低而有利于成本的降低。
The Japanese steel company Fukuyama Steel Works has begun to produce fired pellet sinter agglomerates (HPSs) by retrofitting the existing No. 5 sintering machine with an annual capacity of 6 Mt. Sintered pellets The basic principle of the sintering process is the extensive use of pellets such as fine iron ore powder raw materials, the process has the following three characteristics: 1) with 10 disc pelletizing machines to strengthen the ball to produce high quality The ball of life. 2) Coke powder coke outside the ball to improve coke combustion efficiency. 3) Carefully fabricate with 2 broadband conveyors to prevent the green ball from being broken. Sintered pellet sinter method has the advantages of cheap raw materials, high reducibility and low SiO 2 content, which is beneficial to cost reduction.
