本文主要介绍一种金属镍出炉时间的自动控制方法。在冶镍炉上开一个小孔,近似认为是理想黑体,通过光路选择系统将辐射出的光照射在热电偶上,然后将热电偶上的电压信号用运算放大器放大,可以获得温度和电动势之间的关系。通过一个微控制器形成一个闭环的测温和反馈系统,以构成一个实时的控制系统。 This article mainly introduces a kind of automatic control method of metal nickel baked time. Open a small hole in the smelting furnace, approximately considered to be ideal black body, through the optical path selection system will radiate the light on the thermocouple, and then the thermocouple voltage signal amplified by the op amp, you can get the temperature and emf Relationship between. A closed-loop temperature measurement and feedback system is formed by a microcontroller to form a real-time control system.
