摘　　要：介绍钢水连续测温智能检则系统的工作原理及其所特有的热电偶冷端温度智能补偿技术,其突出特点是采用AD590集成温度传感器,实时有效地解决了热电偶冷端环境温度在摄氏几百度随机变化的高温条件下的自动补偿难题,使系统测温精度大大提高,保证了系统测温偏差在±5℃以内,满足了钢水连铸中间罐和炉外精炼对测温准确度的需要,且系统可多种热电偶选择测量温度。Temporature,as a basic physical quantity,is one of the most universal and important technical parameters. It has a direct affect on targets of many products, such as output,quality and consumption of energy and so on, so measuring of the temperature is very important to industry production. In practice, it is difficult to measure accurately the temperature. Measuring of temperature is different from others, for example, measuring of length ,measuring of mass. The system of continuous measuring of the temperature of hot metal introduced by the paper is the system of 8031 single-chip microcomputer and conventinal measuring component-thermocopule.The mathematic model is appropriate, and measurement method is easy to be executed. The electronic components used are anti-jamming, less zero-drift and less temperature-drift. The system is convenient and applicable. It is steadyl reliable and so fit to use. At the same time, it has larger scope of measurement and it can be used in many kinds of object measured. It has intellectualized the process.
