Abstract: This article investigates the impact of tire blank temperature, capsule thickness, thermal
conductivity, and thermal pipelines on vulcanization time. In winter, the vulcanization time of tire blanks
at low temperatures is 30 seconds longer than that in summer. High thermal conductivity capsules reduce
the vulcanization time by 30 seconds compared to ordinary capsules. At the defoaming position, the
vulcanization time increases by 1 minute for every 1 mm increase in capsule thickness. The series connection
of high and low-pressure pipelines with the addition of a condensate drain tank can effectively reduce
condensed water in the pipeline, solving the consistent problem of insufficient vulcanization inside. The
average vulcanization time in the factory can be reduced by 30 seconds, resulting in a reduction of steam
consumption by 4,969 tons per year and a cost reduction of 1.39 million yuan.
Key words: tire blank temperature; thermal conductivity; vulcanization temperature; cost reduction and
efficiency improvement
