在高炉炼铁生产中,入炉原料称量的准确性是保证高炉冶炼稳定,实现优质、高产、低耗的重要条件。我厂于1984年12月在3号高炉(84m~3)上料系统中采用国产SYS—8个人计算机进行称量补偿及打印、显示用料情况,现场使用取得了初步效果。一、称量补偿系统功能所谓“称量补偿”是指下一批料对上一批料的误差实行“多退少补”的修正,以消除由于零位浮动、卡料及余振量波动造成的累计误差,使实际入炉原料与工艺要求值相一致,从而确保高炉操作制度的稳定。目前,高炉称量补偿系统具有如下功能: (1) 按照上料顺序,逐批打印记录料批号,上料时间、仓号、重量等16个数据; (2) 每班(8小时)打印一次各个原料仓的耗用量累计值;
In blast furnace ironmaking, the accuracy of raw material weighing into the furnace is an important condition to ensure the stability of blast furnace smelting and achieve high quality, high yield and low consumption. I plant in December 1984 in the No. 3 blast furnace (84m ~ 3) feeding system using domestic SYS-8 personal computer weighing compensation and printing, display materials, field use has achieved initial results. First, the weighing compensation system function The so-called “weighing compensation” refers to the next batch of material on the error of a batch of material “Duotuishaobu” amendment to eliminate due to zero floating, Error, so that the actual raw materials into the furnace and process requirements consistent, so as to ensure the stability of blast furnace operating system. At present, the blast furnace weighing compensation system has the following functions: (1) According to the order of feeding, batch printing batch data record, feeding time, warehouse number, weight and other 16 data; (2) Each class (8 hours) The total consumption of raw materials warehouse value;
