摘要

橡胶硫化是橡胶生产中的关键工序，加热系统的性能直接影响产品质量和能源效率。传统的蒸汽加热方式往往存在能耗高、预热慢、温度均匀性差等问题。相比之下，电磁感应加热提供更高的热效率和更快的响应时间。然而，在复杂的几何形状的硫化模具上实现均匀的温度分布仍然是一个重大的挑战。对轮胎硫化机上下加热板和活动模进行了电磁感应加热的热场均匀性研究。通过实验测试与COMSOL模拟相结合，分析了不同线圈结构（前6槽双层线圈、前12槽双层线圈、单层与双层交变线圈、全双层线圈）和材料参数的影响。结果表明，在前12个槽中采用双层线圈，结合镁铝（Mg-Al）合金花纹块，显著提高了温度均匀性。具体而言，模块模具表面的最大温差降至0.61°C，完全在±3°C的工艺要求之内。此外，整个模具的整体温差降至12.29°C，证明了结构和材料综合优化的有效性。

Study on the induction heating thermal field in a vulcanizing machine aimed at temperature uniformity control

Rubber vulcanization is a crucial process in rubber manufacturing, where the performance of the heating system directly impacts product quality and energy efficiency. Traditional steam heating methods often suffer from high energy consumption, slow preheating, and poor temperature uniformity. In contrast, electromagnetic induction heating offers higher thermal efficiency and faster response times. However, achieving uniform temperature distribution across the complex geometry of vulcanization molds remains a significant challenge. This study investigates the thermal field uniformity of electromagnetic induction heating for the upper and lower heating plates and movable dies of the tire vulcanizer. Through the combination of experimental tests and COMSOL simulations, the influences of different coil structures (double-layer coils in the front 6 grooves; double-layer coils in the front 12 grooves; alternating single-layer and double-layer coils; full double-layer coils) and material parameters are analyzed. The results show that using double-layer coils in the front 12 grooves, combined with magnesium-aluminum (Mg-Al) alloy pattern blocks, significantly improves the temperature uniformity. Specifically, the maximum temperature difference on the mold surface of the pattern block is reduced to 0.61 °C, well within the technological requirement of ±3 °C. Additionally, the overall temperature difference across the entire mold is reduced to 12.29 °C, demonstrating the effectiveness of the integrated structural and material optimization.

期刊介绍： The International Journal of Thermal Sciences is a journal devoted to the publication of fundamental studies on the physics of transfer processes in general, with an emphasis on thermal aspects and also applied research on various processes, energy systems and the environment. Articles are published in English and French, and are subject to peer review. The fundamental subjects considered within the scope of the journal are: * Heat and relevant mass transfer at all scales (nano, micro and macro) and in all types of material (heterogeneous, composites, biological,...) and fluid flow * Forced, natural or mixed convection in reactive or non-reactive media * Single or multi–phase fluid flow with or without phase change * Near–and far–field radiative heat transfer * Combined modes of heat transfer in complex systems (for example, plasmas, biological, geological,...) * Multiscale modelling The applied research topics include: * Heat exchangers, heat pipes, cooling processes * Transport phenomena taking place in industrial processes (chemical, food and agricultural, metallurgical, space and aeronautical, automobile industries) * Nano–and micro–technology for energy, space, biosystems and devices * Heat transport analysis in advanced systems * Impact of energy–related processes on environment, and emerging energy systems The study of thermophysical properties of materials and fluids, thermal measurement techniques, inverse methods, and the developments of experimental methods are within the scope of the International Journal of Thermal Sciences which also covers the modelling, and numerical methods applied to thermal transfer.
