The another kind of specific constructive form of above-mentioned preferred embodiment is, electrical heating elements is selected electrical bar or electrothermal tube, and electrical bar or electrothermal tube extend vertically, and radially fit and be distributed in the outer wall surface of metal can in the interval.
When electrical heating elements is selected heating wire, heating wire winding can be located at the metal can outer wall surface and get final product.
The major function of attemperating unit is the temperature in the detection metal can inner chamber and cuts off the electricity supply when exceeding curing temperature, preferred embodiment is that attemperating unit comprises thermometer and electric induction temperature controller.Because it belongs to prior art, the applicant repeats no more again.
For realizing good heat insulation effect, reduce the loss of heat, preferred embodiment be, described metal can outer surface is provided with heat-insulation layer, and electrical heating elements places between heat-insulation layer and the metal can outer wall, and the binding post of electrical heating elements extends the heat-insulation layer outside.Can it is evident that, heat-insulation layer can be selected resistant to elevated temperatures various material as required, such as asbestos etc.
For ease of the movement of planker, be convenient to picking and placeing of workpiece, preferred embodiment be that metal can inner chamber bottom is provided with track, planker and track slidable fit.
The obtained technological progress of the utility model is:
1, the utility model adopts electrical heating as main heat form, and its simple structure is practical, has solved the environmental issue because adopting the vapours sulfuration to use boiler to bring.
2, adopt the structural design of hot air circulation pipeline, ingeniously finished inner thermal cycle, avoided because of the workpiece inhomogeneous problem of slaking that inequality causes of being heated.
3, metal can adopt vessels not under pressure, and its making is simple, uses safety, has solved making difficulty and the use security problems that must adopt pressure vessel to bring because of steam vulcanization (cure).
