摘要
硫化机热板表面温度均匀性是衡量硫化机械设备性能优劣的重要指标。运用FLUENT软件进行仿真分析并结合实验验证,研究了硫化机热板温度场分布规律并对热板的机械结构进行改善。针对规格为1760 mm×1 760 mm×80 mm的热板建立了有限元模型,研究了热板加热油液通道结构分布情况及导热油流速对热板温度场的影响规律,并对热板通道排布结构参数进行了改进。比较分析改进前后方案,结果表明:热板表面温差由原先4.6℃降低为3.1℃,温度均匀性提高了33%,通过实验研究进一步验证了模拟结果的可靠性,结构改善后的热板在实际生产中的产品,质量显著提高。
The temperature uniformity on the surface of the hot plate of the vulcanizing machine is an important index to measure the performance of the vulcanizing machinery.In this paper,FLUENT software is used for simulation analysis and experimental verification is combined. The temperature field distribution of heat plate of vulcanizing machine was studied and the mechanical structure of hot plate was ameliorated.The finite element model was established for the hot plate of 1760 x 1760 x 80(mm).The structure distribution of hot plate heating oil channel and the influence rule of the thermal flow velocity on the thermal plate temperature field were studied.The structure parameters of hot plate channel are ameliorated. The results show that the temperature difference of the surface of the hot plate is reduced from 4.6 C to 3.1,and the temperature uniformity is increased by 33%. The reliability of the simulation results is verified by experimental study. The quality of the hot plate after the structure improved has been greatly increased in the actual production.
