实心轮胎均匀硫化工艺的研究

Study on Uniform Vulcanization Technology of Solid Tire

将电磁感应加热技术应用于实心轮胎外模具和轮辋加热,并以某规格实心轮胎为试验对象进行空载测温试验,研究实心轮胎均匀硫化工艺。结果表明:外模具内腔表面温升迅速,上下模体温差小,热效率高,节能效果明显;轮辋在电磁感应作用下升温效果明显提高,可以缩短轮胎硫化时间,提高轮胎硫化质量。

The electromagnetic induction heating technology was applied in heating the external mold and rim of solid tire during vulcanization. Taking solid tire vulcanization as an example, the temperature measurement was carried out without actual load, and the uniform vulcanization technology was studied. The results showed that, the temperature of mold cavity increased rapidly, uniform temperature distribution could be achieved, and the heat efficiency was high which saved energy signifi- cantly. Under electromagnetic induction, the heating of the rim could be greatly improved. As a result, the tire curing time was reduced and the performance of the finished tire was improved.
