Problems solved by technology

The temperature difference is likely to cause uneven heating of tire vulcanization, inconsistent vulcanization degree, uneven quality, and even under-sulfur phenomenon in the lower mold of the tire. However, delayed vulcanization can only be used in the process, which will not only cause uneven vulcanization of the tire locally, but also give Product quality brings great hidden dangers, resulting in the average service life of tires being only 4 to 5 months; in addition, the damage to the bladder is large, the utilization rate of the bladder is low, and the production cost is high

Abstract

The invention relates to giant all-steel OTR radial tire nozzle-type hot-water circulation vulcanization equipment and a vulcanization technology. The equipment comprises a vulcanization die and a water inlet pipe arranged on the vulcanization die. The vulcanization die is provided with a capsule, inside which a nozzle tube communicated with the water inlet pipe is arranged.

Description

technical field [0001] The invention relates to an all-steel engineering machinery tire, in particular to a nozzle-type hot water circulation vulcanization equipment and vulcanization process for a giant all-steel engineering radial tire, belonging to the technical field of rubber. Background technique [0002] Affected by the global economy, the current economic situation at home and abroad is still grim, and the industry related to all-steel radial tires is not optimistic. Whether it is medium-to-long-distance transportation or medium-to-short-distance load, the demand for tires generally declines. The demand for big, giant all-steel OTR tires is rising sharply. In the past two years, although the excavation equipment and heavy-duty transport vehicle market has grown at a rate of 20% every year, it still cannot meet the market demand. Countries with ore resources such as Brazil, Australia and Canada have also increased mining efforts at a growth rate of 20% in recent year...
