All-steel engineering tire variable-temperature vulcanization technology

The invention provides an all-steel engineering tire variable-temperature vulcanization technology. A mold, a tire and a capsule are sequentially arranged from outside to inside. The temperature in the capsule is the inner temperature, the temperature outside the mold is the outer temperature, and the inner and outer temperatures are all variable. Previously, high-temperature steam with the temperature being 170-180 DEG C is led into the capsule to rapidly raise the temperature of the tire, then the high-temperature steam is switched into high-temperature and high-pressure circulation water, vulcanization is conducted for a certain time, the pressure is kept, circulation is stopped, and the inner temperature is naturally decreased to 15-40 DEG C; and latterly, outer temperature steam is stopped to enable heat on the surface of the tire to be continuously conducted to the interior of the tire, and the surface temperature is gradually decreased.
