Abstract: Vulcanizing machine is an important equipment in rubber plant. How to make the vulcanizing machine work well is related to many issues such as product quality, production efficiency and production cost. Moreover, the steam trap is a key component affecting the normal operation of the vulcanizer . Therefore, according to the technical requirements of the product, a vulcanization process is formulated, and the temperature rise time, temperature time and temperature fluctuation range of the vulcanizer are stipulated. 1. Characteristics of steam traps trap type
