Simulation of Resistance Furnace Temperature Control System Based on Matlab
Resistance furnace as an important industrial heating equipment for parts heat treatment,is a use of current through the resistance material heat furnace,resistance furnace in the field of machinery is mainly used for metal forging before heating,powder metallurgy sintering,glass ceramics roasting and annealing,low melting point metal melting and so on.Compared with flame furnace,resistance furnace has the ad-vantages of simple structure,uniform furnace temperature,good heating quality,easy control and no noise.As an important heat treatment e-quipment,the temperature control of the resistance furnace is directly related to the quality and precision of the production parts.But the tem-perature change of resistance furnace has a strong delay and inertia,so it is of great significance to establish an effective temperature control system to improve the temperature control level of resistance furnace.The principle of fuzzy PID algorithm is analyzed firstly,and then intro-duces the overall design scheme,hardware design and software design of the temperature control system based on the SX-10-12 box-type re-sistance furnace,and discusses the operation of the temperature control system in the Matlab simulation environment,aiming to improve the automation level of the temperature control of the resistance furnace.
