Partition Structure and Temperature Control Technology of Seal-Style Tunnel Electric Oven

Lin Ruobo;Lin Rongcai;Jieyang Vocational and Technical College;Guangdong Fengsheng Machinery Co.,Ltd.;  
Aiming at the existing problems of the traditional open type tunnel oven,the partition structure of seal-style tunnel electric oven is developed,which uses the partition heat insulation technology to realize accurate control of the temperature of zone,improve temperature control stability and energy saving by means of seal-style heated air circulation system.The paper proposes a gearshift integral PID algorithm to solve the problem of temperature hysteresis nonlinear and achieve rapid temperature control.The test results show that the steady speed of seal-style tunnel oven is faster than traditional tunnel oven with small-fluctuation temperature of ±1℃ control scope.
