Based On The Research Of Electromagnetic Sulphuration Apparatus Temperature Field Uniformity

The traditional rubber vulcanization method of steam heat conduction and hot oil heat transfer as the main heat source,the waste of energy in the vulcanization process and the pollution to the environment is inevitable,in addition to the vulcanization device should be equipped with heat source transfer device and carry out regular maintenance,on the other hand greatly increased the initial investment cost.With the progress of The Times,science and technology continue to bring forth the new,the traditional heating method has been unable to meet the needs of industrial equipment,high efficiency,energy saving,environmental protection,intelligent processing and manufacturing concept has become the mainstream of modern industrial development.To cater to the needs of The Times,in this paper,on the basis of plate vulcanizing machine,using electromagnetic heating device to heat source,in the induction heating process of electromagnetic field and eddy field and temperature field are studied,to get steady uniform temperature distribution in the hot plate,and through the analysis of the theoretical deduction and computer simulation system for validation,can hope to electromagnetic heating technology is widely used in the field of rubber vulcanization provide a little reference value.The distribution of electromagnetic field in the process of induction heating is studied.Electromagnetic field is the energy field in the whole process,and its distribution in the whole system determines the working efficiency of the whole heating system.Through theoretical derivation and computer software modeling analysis,the distribution law of magnetic field in the coil plane and the whole space and various factors affecting its distribution are studied,the structure of the coil,the physical performance parameters of the hot plate and the applied load are pointed out as the main influencing factors,and the "dead zone" is found in the center of the coil plane.The distribution of the eddy current field on the plate is studied.The eddy current field is the heat field in the heating process,and its distribution determines the heat distribution of the whole system.In view of the different distribution of the eddy current generated by the hot plate structure in the magnetic field,the heating rate and equilibrium of the two conditions are simulated and analyzed.Study the steady state temperature field on the hot plate,its on the hot plate to determine the distribution of the heating quality of the whole device,a comparative analysis of temperature fields generated by different coil shape,based on optimization of the structure of coil,increase the core material,to obtain more uniform magnetic field distribution,and the optimized magnetic field distribution is obtained by simulation,to validate the guess.This paper studies the distribution of electromagnetic field,eddy current field and temperature field in the process of induction heating,and obtains the influence of coil structure,physical properties of hot plate and applied load on the final heating effect through the simulation analysis of theoretical derivation,which has certain guiding significance for the actual production and processing.
