Described body of heater (11) side is provided with radiator (13), this radiator (13) is near described temperature controller (3) and communicating with described body of heater (11) inside, because temperature controller is arranged on solder furnace side, and circuit part is positioned at solder furnace body of heater, functionally can be subject to the impact of thermal environment, radiator is set and be crossed the impact of thermal environment to reduce temperature controller and circuit part;
Being provided with high temperature resistant heat insulation cotton (12) between described inner bag (5) and described body of heater (11), on the one hand in order to reduce scattering and disappearing of inner bag heat energy, reducing inner bag on the other hand to the impact of body of heater;
Described inner bag (5) inner surface is coated with one deck ceramic layer, prevents high temperature scolding tin from corroding solder furnace inner bag, makes solder furnace inner bag Non-Dewetting simultaneously and do not produce tin ash;
Described inner bag (5) bottom is provided with ceramic heating flake standing groove (15), is convenient to change ceramic heating flake.
Beneficial effect of the present invention is: adopt ceramic heating flake interlayer inner homogeneous heating inner liner at the bottom of inner bag, not only eliminating scolding tin because heating uneven and oxidized problem, can also make full use of the energy; To scolding tin ullage spray inert nitrogen gas, reduce the amount that scolding tin contacts with air, the more effective scolding tin that prevents is oxidized; The automatic scraping scruff push pedal of design, structure is simple, makes the more convenient practicality of the present invention.
