The results show that the total zinc amount entering into the blast furnace is nearly balanced with the overflowing amount of zink in stable operation conditions; the main factor which effects on Zn load of blast furnace is the Zn content of sinter ore ,it can reach to 50% of the total content,the Zn content of the BF is carried out by sluage ,it brings out 70% of total expenditure.

结果表明：在高炉正常的冶炼条件下，进出高炉的锌的总量基本上保持平衡；入炉原燃料中，以烧结矿带入的锌最多，可以达到50%以上，而在锌的支出方面则主要通过污泥，几乎可达到支出总量的70%左右。

The process basic scheme, configuration of the control system and its main functions are described. The master, controller and control net are reduplicated on purpose to improve the reliability of the control system, When TRT trips, one of the valves group for reducing gas pressure is opened fast to avoid the increase of blast furnace top pressure rapidly. In order to stabilize the roof pressure of the blast furnace during TRT oper...

为了提高控制系统的可靠性，系统的服务器、控制器及网络均按冗余方式配置；TRT跳闸时，为了不使高炉炉顶压力急剧上升，采用了减压阀组的紧急开放阀快速打开的控制策略；为了达到在TRT运行过程中稳定炉顶压力的目的，在可调静叶控制中使用了一种可初始化的回馈计算回路。
