The shell is integrally sealed, the cover is sealed with silicone mud, the furnace door is equipped with a silicone pad and a water cooling system is passed. There are burners at the inlet and outlet of the furnace, which can be pre-evacuated and can pass hydrogen, argon, nitrogen, oxygen, carbon monoxide, ammonia decomposition gas and other gases. The furnace has a balanced temperature field, low surface temperature, and rising and falling temperatures. Fast speed, energy saving and other advantages, it is an ideal product for atmosphere protection sintering and atmosphere reduction in universities, research institutes, industrial and mining enterprises.

1.Swedish Kanthal A1 resistance wire

Kanthal A1 raw silk domestic resistance wire hearth VS imported resistance wire hearth

(1), the surface temperature can reach 1420

(2) The surface is stainless steel (very bright, pay attention when customers identify it), will not rust, and will not drop slag even if it is used for a long time.

(3), Kanthal resistance wire data download

(4) Kanthal resistance wire website: www.kanthal.com

(5), resistance balance, temperature field balance is good

Fe-Cr-Al Alloy doped by Mo resistance wire produced by Shougang used by most manufacturers Kanthal A1 resistance wire has uniform resistance and balanced heat generation

Sometimes the resistance is unbalanced, part of the heat is large and part of the heat is small.

2. Installed air switch and leakage protector:

When the circuit is over-current or leakage, the meeting will be disconnected automatically.

3.Can connect with computer

The furnace is equipped with a communication interface and software, which can directly control various parameters of the furnace through a computer, and can observe the PV and SV temperature values on the furnace and the operation of the instrument from the computer. The actual heating curve of the furnace will be drawn by the computer in real time And can save the temperature data at each moment, you can call up at any time

Sealing system: The furnace top cover and the furnace door (already welded elsewhere) are extruded and sealed with silicone O-rings, easy to remove, repeatable removal, good air tightness, which can ensure that the pointer of the pressure gauge does not deflect for 8 hours. .

Vacuum system: pre-evacuation of the atmosphere box furnace can be used to accelerate the cleaning of the air in the furnace.

Gas supply system: The furnace is equipped with a float flow meter. Customers can control the flow rate of the gas through a float flow meter or a proton flow meter.

Air outlet valve: The air outlet valve is a one-way valve, and the gas can only flow out but not back.

(Optional) Explosion-proof system: Explosion-proof system is composed of solenoid valve, microcomputer, pressure display and transmitter, 24V power supply, AC contactor, etc. The pressure in the furnace is converted into an electric signal and transmitted to the microcomputer through the pressure display and the transmitter. The microcomputer compares with the set value and then gives a signal to control the AC contactor to control the on-off of the solenoid valve. When the pressure in the furnace is greater than the allowable pressure we set, the solenoid valve opens immediately to play an explosion-proof role. We have installed a gas outlet pipe on the solenoid valve, and the user can connect the pipe to exhaust the gas to the outside, and the explosion-proof valve is one-way The valve can only exhaust and cannot return, which effectively ensures the safety of the furnace.

This explosion-proof system has many advantages:

(1) Reusability: The solenoid valve opens when the pressure is higher than the set value, and closes when the pressure is lower than the set value. Unlike a mechanical riot device, it cannot be used once it is burst.

(2) Adjustable set value: The user can adjust the opening pressure of the solenoid valve through a microcomputer as required

(3) Explosion-proof point is very sensitive: due to the use of microcomputers and electrical signals, the explosion will start as soon as the pressure reaches the explosion-proof point.

(4) Safety of explosion-proof system: no fragments fly out during explosion. (If the mechanical method is used, glass sheets may fly out)

(5) The stability of the explosion-proof system is good: due to the use of a microcomputer and a solenoid valve, it will definitely explode to our set point, and the user can test, unlike the mechanical type, which cannot be tested, there are a lot of problems Certainty.


(Optional) Under pressure alarm system: When the pressure in the furnace is lower than a standard atmospheric pressure (this pressure value can be adjusted), the electric furnace will automatically alarm, indicating that the intake air flow is insufficient, and can decide whether to cut off the heating circuit power according to customer needs .


(Optional) Gas supply system: The furnace can be equipped with 2 or 3 float flowmeters. The flow rate of the gas can be controlled by the float flowmeter. There is a stainless steel valve at each air inlet. You can choose one or more of them. The gas is adjusted. After passing through the flowmeter, the gas enters the mixing tank, and then enters the furnace separately in 3 ways, so that the gas can be evenly flowed into the furnace.


(Optional) Vacuum system: Pre-evacuation of the atmosphere box furnace can be performed to accelerate the cleaning of the air in the furnace.


(Optional) Combustion device: The furnace can be equipped with a hydrogen burner to burn the gas discharged from the furnace.


(Optional) Water cooling system: The furnace is equipped with a water cooler, which can automatically cool the doorway of the road.
