Upper layer is used for welding rod drying, directly heating.

Lower layer is used for inlayer.

Product Features
High-quality resistance wire is used as the heating element, and a double-layer shell structure is adopted.
The controller is installed under the furnace door to save space and meet various fast sintering requirements. Microcomputer PID controller is easy to operate, and the temperature control is accurate, reliable and safe. ·The furnace chamber is made of alumina polycrystalline fiber material to ensure durability. ·Excellent door sealing minimizes heat loss and increases the uniformity of temperature in the furnace. ·The double-layer furnace shell is equipped with an air cooling system, which can quickly increase and decrease the temperature.
Multi-segment programmable controller
The microcomputer program controls the temperature, time and heating speed, and other programs, and performs various sintering tests at a very fast speed. Programmable controller, 51-segment program temperature control system, phase shift trigger, thyristor control. ·Adopting microprocessor P.1.D control method, multi-segment programmable control, truly realize automatic control and operation.
Safety function
It has over-temperature protector, door switch controller, cooling fan on the box surface and abnormal alarm function of resistance furnace (heater failure, ② temperature sensor failure, ③ memory content abnormality, ④ over-temperature abnormality), and sound and light alarm to remind the operator to ensure the safe operation of the resistance furnace without accidents.
It has multiple safety protection measures such as over-current, over-voltage, over-heating, etc. to ensure the safe use of the electric furnace. Ceramic fiberboard is selected as the thermal insulation material, which has good thermal insulation effect and low box shell surface temperature.
