一、概述 在工业生产过程中,为了有效地进行生产操作,需要对有关参数如温度、压力、流量等进行自动检测。冶金生产过程中的特点是工艺过程连续且大部分在高温中进行,如高炉冶炼中必须控制热风温度才有利于生产操作;平炉、转炉冶炼过程中都必须正确掌握熔池温度,才能快速冶炼、降低能耗、延长炉龄、增加产量;随时掌握加热、轧制全过程中的钢材表面和中心温度,才能保证轧
First, an overview In the industrial process, in order to effectively carry out production operations, the need for the parameters such as temperature, pressure, flow, etc. for automatic detection. Metallurgical production process is characterized by continuous and most of the process carried out at high temperatures, such as blast furnace smelting must control the temperature of hot air is conducive to production operations; open hearth, converter smelting process must correctly grasp the temperature of the molten pool in order to smelt quickly, Reduce energy consumption, extend the furnace age, increase production; keep abreast of the heating, rolling the entire surface of the steel and the center temperature in order to ensure the rolling
