首都钢铁公司新2号高炉是我国目前唯一使用皮带上料的无料钟炉顶高炉,容积1327m~3。在这座高炉上,首次应用可编程序控制器和矩阵型顺序控制器,对上料系统进行自动控制。但是,由于目前的电气控制系统和仪表缺少记忆、计算和补偿功能,因而无法保证入炉原料重量的准确性,造成入炉料累计误差很大。以焦炭为例,仅23批料的累计误差
Capital Iron and Steel Company No. 2 blast furnace is the only use of belt material in our country without bell bell furnace, volume 1327m ~ 3. In this blast furnace, the first application of programmable logic controller and the matrix sequence controller, the feeding system for automatic control. However, due to the lack of memory, calculation and compensation functions of the current electrical control systems and instruments, the accuracy of the weight of the raw materials can not be guaranteed, resulting in a large cumulative error in the charging of materials. Take coke as an example, only the cumulative error of 23 batches of material
