1 前言烧结机上不同横向位置的烧结料层的烧结条件是不一样的。而且,在整个烧结时间内的任一指定时刻,这些条件都会产生波动。尤其在大型烧结机上,这些变化和波动较大。此外,烧结条件与烧结矿质量和成品率密切相关。因此,烧结条件达到均匀和稳定,不仅可以使烧结矿质量和成品率得到改善,而且可以提高烧结生产率。日本钢管公司京滨厂开发烧结料层加热方式控制系统,就是为了使烧结条件达到均匀和稳定。该系统已应用到扇岛1号烧结机(有效烧结面积=5m×90m=450m~2)上。它由两个子系统组成:一个是烧结料层横向加
1 Introduction Sintering machine in different horizontal position sintering sintering conditions are not the same. Moreover, these conditions fluctuate at any given time throughout the sintering time. Especially in the large sintering machine, these changes and fluctuations. In addition, sintering conditions are closely related to sinter quality and yield. Therefore, the uniform and stable sintering conditions not only improve the sinter quality and yield, but also improve the sintering productivity. Japanese steel pipe company Keihin plant development sintering layer heating mode control system, is to make the sintering conditions to achieve uniform and stable. The system has been applied to the fan island 1 sintering machine (effective sintering area = 5m × 90m = 450m ~ 2) on. It consists of two subsystems: one is the sinter layer horizontal plus
