Abstract: This study comprehensively validated and evaluated the electric heating nitrogen curing
process used in 14.9-24-8PR CB538 bias tires. The research results indicate that this process is comparable to
traditional superheated water sulfurization process in terms of sulfurization efficiency, while its sulfurization
cost is similar to nitrogen sulfurization process. Under current electricity pricing conditions, the electric heating
nitrogen curing process reduces energy consumption costs by about 20% compared to the nitrogen curing process,
demonstrating significant energy-saving potential. However, the temperature difference ( ≥ 10 ℃ ) between the shoul
der and crown centers of the tread during the vulcanization process indicates that the uniformity of vulcanization
still needs further optimization. This study not only provides empirical basis for the application of electric heating
nitrogen curing process in tire production, but also comprehensively evaluates its vulcanization effect and energy
consumption performance, confirms its advantages in energy conservation and environmental protection,
and points out future research directions. These directions include improving vulcanization uniformity,
optimizing process parameters, and exploring the applicability of this process under different tire models and
production conditions, aiming to promote the development of tire manufacturing towards high efficiency,
energy conservation, and environmental protection.
Key words: electrically heated nitrogen curing; bias ply tire; curing efficiency; energy consumption
