一、概述 在高炉本体工艺一定的条件下,高炉电控设备的自动化程度,尤其是配料,上料过程的自控水平,对提高生铁产量与质量是至关重要的。由于受生产条件及维修力量等因素的限制,目前小型高炉控制水平仍比较低,大多还是手动操作。针对小型高炉的一些特点,我们以日本三菱公司F_2-60MR加强型可编程序控制器为主控单元,配以键盘显示
I. Overview In the blast furnace under the conditions of certain technology, the degree of automation of blast furnace electric control equipment, especially the ingredients, feeding process of the level of control, to improve pig iron production and quality is crucial. Due to production conditions and maintenance forces and other factors, the current small blast furnace control level is still relatively low, mostly manual operation. For some of the characteristics of small blast furnace, we Japan’s Mitsubishi F_2-60MR enhanced programmable logic controller as the main control unit, together with the keyboard display
