The utility model discloses a vulcanization system, and belongs to the field of rubber roller vulcanization equipment. In the prior art, the vulcanization efficiency of a rubber roller is low; the consumption and waste of energy such as heat and steam are large. The utility model provides a vulcanization system. The device comprises a boiler, the device further comprises a vulcanizing tank A and avulcanizing tank B, the vulcanizing tank A is communicated with the vulcanizing tank B through a vulcanizing gas pipeline; wherein the vulcanizing tank A and the vulcanizing tank B are oppositely arranged, the boiler is communicated with a vulcanizing gas pipeline through a communicating pipe, a gas inlet valve is arranged between the communicating pipe and the pipeline, a tank A gas inlet valveand a tank A exhaust valve are arranged on the vulcanizing tank A, and a tank B gas inlet valve and a tank B exhaust valve are arranged on the vulcanizing tank B. The two opposite vulcanizing tanks are arranged, so that the vulcanizing efficiency is high, the pressure and steam in one vulcanizing tank are transmitted into the other vulcanizing tank after the vulcanizing of one vulcanizing tank isfinished, the energy consumption is reduced, the condition that the next vulcanizing can be carried out after the vulcanizing tank is vulcanized and decompressed is changed, the structure is simple, and the manufacturing is easy.
