Apparatus for continuously vulcanizing rubber product
 An apparatus for continuously vulcanizing a rubber molding extruded from an extruder is disclosed in which a single or plural microwave heating apparatus is arranged within a heating bath. The microwave heating apparatus can generate internal heating of the rubber molding so that a surface temperature of the rubber molding can be held at a temperature substantially equal to the internal temperature of the rubber molding. Thus, uniform vulcanization of the rubber molding occurs. In addition, when both the microwave heating apparatus and an external heating source are arranged within the heating bath, an infrared ray radiator, arranged within the heating bath, radiates infra-red rays according to energy absorbed from the microwave heating apparatus and the external heating source. Thus overall heating efficiency can be increased. Furthermore, when single or plural temperature sensors are arranged within the heating bath so as to detect temperatures on particular portions of the rubber molding, an on-and-off control of the microwave heating apparatus is carried out so as to maintain the temperature of the rubber molding on the basis of a previously set temperature.
