1 绪言随着钢铁工业经济环境的变化,对炼铁部门来说,降低烧结矿生产成本是一个十分重要的课题。川崎钢铁公司千叶钢铁厂以前一直以多配用低价原料、生产低SiO_2烧结矿来降低成本;同时,通过新型点火装置的开发、余热回收设备的引进、烧结生产管理的系统化等措施,降低烧结能耗和烧结矿生产成本。该厂不仅开展了操作技术的改进工作,还在1987年5月将第三烧结车间停产,实行了向第四烧结车间倾斜的政策。所以,在防止烧结矿生产成本上升的同时,达到高生产率操作就成了第四烧结车间的课题。一般,在高生产率操作条件下,随着烧
1 INTRODUCTION With the changes in the economic environment of the steel industry, it is a very important issue for the iron-making sector to reduce the cost of sinter production. In the past, Kawasaki Steel’s Chiba Steel Plant has been using multiple low-cost raw materials to produce low-SiO 2 sinter to reduce costs. At the same time, through the development of new-type ignition devices, the introduction of waste heat recovery equipment and the systematization of sintering production management, Reduce the sintering energy consumption and sinter production costs. The plant not only carried out the improvement of operating technology, but also in May 1987 the third sintering plant was discontinued, the implementation of the fourth sintering plant tilt policy. Therefore, to prevent the cost of sinter from increasing, it has become a subject of the fourth sintering plant to achieve high productivity operation. In general, under high productivity operating conditions, with the burning
