题 目：电阻炉温度控制系统设计 电阻炉温度控制系统设计 摘 要关键词： Resistance furnace temperature control system Abstract Along with sciences and technologys swift development, the control theory is unceasingly rich and is perfect, the control technology also to the intellectualization, openness, the redundant reliable direction develops. At present the commonly used control mode has the intellectualized measuring appliance, PLC, DCS, they may compose each kind of control system to satisfy the technique of production the request. Its function is getting more and more formidable, the performance to be getting more and more perfect, and has the control precision to be high, antijamming ability is strong, What the explosion-proof strong and so on characteristic this article studies is resistance furnaces temperature control system, because resistance furnace in produces and in the life application is quite widespread, therefore resistance furnaces temperature control appeared especially important, established a control system first to aim at the controlled member to conduct the research. This designs object of study is the laboratory existing tubular resistance furnace, therefore this article has carried on the object performance test to it. Then in view of resistance furnaces characteristic, proposed use component composition temperature control systems and so on digit regulator, solid state relay, realize through the adjustment parameter to the resistance furnace temperature control. This method economical, simple, easy to operate, the control precision is high. What is most main: Grasps using the laboratory existing equipment designs the work which a control system , the more profound understanding design control systems thought that for the later study, the work has built the solid foundation.
