1. Heating element

(1) the hot end roughness D1 of the silicon molybdenum rod is 7mm, the average manufacturer adopts 6MM, the heating end is thick, the surface load of the rod is low, and the service life is long.

(2) it adopts hot bending technology, with uniform resistance and long service life

(3) the length of the cold end of the Lu is 210mm, 400X300X300 furnace is 260, the general manufacturer adopts 180mm, and the cold end has a low temperature.

(4) the surface oxidation of silicon molybdenum rod is compact and can better protect the silicon molybdenum rod.

2. Install air switch and leakage protector:

When an electric current or leakage, an empty meeting automatically disconnects.

3. Can connect with computer

This furnace is equipped with communication interface and software, can be directly through the furnace computer control of each parameter, and can be observed from the computer PV on the stove and SV temperature value and instrument operation, the actual temperature of the furnace curve drawing computer real time, and can keep the temperature data of each time, can call up at any time

4.Chamber

      Imported                           VS                     Chinese

1. High quality high pure alumina polycrystalline fiber cured furnace with vacuum suction and filter molding.

2. Adopt Japanese technology to form.

3. The spacing and pitch of the resistance wire in the furnace are arranged according to the best thermal technology of Japan, and the temperature field is simulated by thermal software

4. Using 4 weeks heating, the temperature is more balanced The furnace can not remove powder, heat insulation, high reflectivity and temperature balance, which is strong against heat and shrinkage

5. Optional UL certified electrical board (all imported electrical appliances approved by UL)

6. Trigger 

  VS 

Soft start limited flow trigger   Most of the manufacturers use the non - limited Xiamen botany trigger

1. Phase shift trigger (with soft start and current limiting function)

2. Current limiting function: no matter how the heating time is adjusted, the secondary current of our electric furnace after the transformer is limited to 170A, and the equipment is limited. Unlimited-flow triggers, if the heating rate is set wrong or too fast, The current is so large at low temperature that the device can trip or burn.

3. Soft start function: the current will gradually increase when starting up, and the impact on the heating element will be small, which will help to prolong the life of the heating element

4. Protection function: if the current exceeds the limiting current, the trigger will automatically cut off the trigger function to cut off the current protection furnace.

7. UL certified transformer

1. The transformer cable is pure copper 

2. Small transformer 

3. Low temperature of transformer

 The stainless steel tank of hydrogen atmosphere furnace is installed in the chamber of a stove or furnace a stainless steel tank, the tank oven door USES silicone O ring seal, in order to reduce O ring seal temperature in the furnace door is equipped with water cooling system, thermocouple, inlet valve, the valve installed on the tank, pressure gauge, etc; This furnace installation with hydrogen detector, burner, the combustion controller, alarm lights, torches, explosion-proof valve, etc., after gas after flow meter by chamber in and out, tail gas from the door of the oven after cooling water system. Can pass, argon, nitrogen, oxygen, hydrogen gases such as carbon monoxide, ammonia decomposition gas, &energy-saving equilibrium temperature field, the surface temperature is low, lifting speed, energy saving, clean furnace temperature is not easy to contaminated, universities, research institutes, industrial and mining enterprises do protect the sintering atmosphere, reducing atmosphere, skim the ideal product.
