摘　　要：宣钢2号回转窑除尘控制系统全部是手动控制,在生产大约半年的过程中,链篦机内侧及风机系统内的耐火材料损坏严重,通过数次定修对上述两处的耐火材料进行了修补,工耗能耗损失巨大,严重制约现用球团系统的正常运行;球团矿的成品质量也出现数据波动,球团矿的颗粒硬度及入炉后熔点与计算不符,给炉况及焦比控制带来影响。此次系统升级涉及到的程序优化内容、设备模件的增删修正方式,在其他生产设备中均可通用,符合宣钢回转窑生产需求。项目实施所用设备选型主要考虑与1号回转窑自控设备可实现互替,来节约备件费用。并且其中部分功能的实施可通过程序编辑优化实现,不需要材料费用的投入。在方案实施过程中,通过反复模拟试验和实际运行,证实其可行且稳定,具备在线使用条件。The transformation and optimization of the stepper machinery of the heating furnace.The dust removal control system of the No.2 rotary kiln at Xuangang is all manually controlled.During the production process of about half a year,the refractory materials inside the grate and fan system were severely damaged.The refractory materials at the above two locations were repaired through several regular repairs,resulting in huge losses in labor consumption and energy consumption,severely restricting the normal operation of the current pellet system;The quality of the finished product of pellets also fluctuates,and the particle hardness and melting point of pellets after entering the furnace do not match the calculation,which affects the furnace condition and coke ratio control.The content of program optimization and the method of adding,deleting and modifying equipment modules involved in this system upgrade can be used in other production equipment,which meets the production requirements of Xuangang rotary kiln.The selection of equipment for project implementation mainly considers the possibility of mutual replacement with the automatic control equipment of the No.1 rotary kiln to save spare parts costs.And the implementation of some of these functions can be optimized through program editing,without the need for investment in material costs.During the implementation process of the plan,it was confirmed through repeated simulation experiments and actual operation that it is feasible and stable,and has the conditions for online use.
