提高产品质量、节约能源、延长炉龄等是热轧钢管加热炉炉温自动控制的重要任务。 我厂和重庆工业仪表自动化研究所共同研制的、以M6800微型机系统为核心的过程控制装置,自1981年3月份投产以来,经一年多的炉温控制运行,在上述几个方面都取得了较好的效果。 Improving product quality, saving energy and prolonging furnace age are important tasks in the automatic control of furnace temperature of hot-rolled steel pipe heating furnaces. I plant and Chongqing Institute of Industrial Automation Instrument jointly developed by the M6800 microcomputer system as the core of the process control device, put into operation since March 1981, after more than a year of temperature control operation, made in the above aspects A better effect.
