福建省三明化工厂电石厂的电石炉(即埋弧炉)是个用电大户,人称“电老虎”。多年来,电石炉由人工操作,炉温高,条件恶劣,工艺落后,劳动强度大,生产效率低。为此,我们与三明化工厂电石厂联合研制了电石炉生产过程微机控制系统。采用定时采集数据,实时控制原理,实现电极自动压放,功率自动调节,自动加料及变压器的冷却系统的巡测,整个系统还配接了汉字显示终端和打印机,做到了实时工业控制和生产管理并用,收到了明显的经济效益。
Fujian Sanming carbide calcium carbide electric furnace factory (that is, submerged arc furnace) is a large electricity, known as the “electric tiger.” Over the years, calcium carbide furnace by the manual operation, high temperature, poor conditions, technology behind, labor-intensive, low production efficiency. To this end, we and Sanming Chemical Factory calcium carbide plant jointly developed calcium carbide furnace production process microcomputer control system. Adopt timed data collection, real-time control principle, to achieve electrode automatic pressure drop, automatic power adjustment, automatic feeding and transformer cooling system inspection, the system is also equipped with Chinese display terminals and printers, so that real-time industrial control and production management And used, has received significant economic benefits.
