STEEL BAND TYPE CONTINUOUS VULCANIZING EQUIPMENT

摘要

PURPOSE:To improve absorbing efficiency of heat without necessitating a large- volume heating medium, by applying heating to a steel band by inducing directly an induction current to the steel band. CONSTITUTION:A plurality of hot plates 16a-16c are arranged on the backside of a steel band 3, a high-frequency induction coil 17 and insulator 18 are arranged on the hot plate close to the steel hand 3 and an insulation material 9 and racking material 10 are provided on the outside of the insulating material 18. The hot plates 16a-16c are so constituted that temperature sensors 19a-19c are provided respectively on them and in the case where the hot plate has become a preset temperature (about 145 deg.C), a heating temperature of a steel band 3 is controlled by a controller 21 through a convertor 20. As the the high- frequency induction coil 17 has been provided close to the steel band 3, the title equipment can apply induction heating directly to the steel band 3 and turns superior extremely in absorbing heating efficiency at the time of vulcanization.
