Ultra-high temperature vacuum atmosphere furnace

Vacuum atmosphere furnace, also known as anaerobic annealing furnace, vacuum atmosphere sintering furnace, the object access to certain gas-open vacuum atmosphere tube furnace sintering method.

Vacuum atmosphere furnace technical indicators parameters:
Common temperature of 1400 degrees, temperature control accuracy of ± 1 ℃, integrated circuit control, no overshoot phenomenon. Furnace temperature uniformity of ± 3 ℃, temperature measurement element thermocouple platinum and rhodium S thermocouple, temperature range 0-1700 degrees, the heating element installed position: both sides (using silicon carbide heating), the heating rate can be adjusted freely, the adjustment range : The fastest heating rate of 40 degrees per minute (40 ℃ / min), the slowest heating rate of 1 degree per hour (1 ℃ / h).
Vacuum atmosphere furnace atmosphere control: the electric furnace inlet hole in the top of the furnace, the outlet in the lower part of the furnace; you can add a variety of gases (oxygen, nitrogen, argon, hydrogen, carbon monoxide, etc.) and vacuum; Pressure relief valve, and preheat air intake function, the use of floating ball flow meter flow meter, but also root needs of customers need to increase the digital mass flow meter for precise control of the intake.
Vacuum atmosphere furnace vacuum: vacuum gauge indicates -0.1MPa, positive pressure 0.3MPa

Safety: electric contact pressure switch with electric contacts to prevent the furnace has a high positive pressure to prevent high temperature power outage, the furnace design explosion-proof valve!

Vacuum atmosphere furnace cooling structure: double shell, air + water cooling, with circulating water pump and circulating water tank (300 liters), door, furnace mouth, roof cooling three parts.

Vacuum atmosphere furnace shell part:
1, Exquisite Appearance Furnace is made of CNC machine tool and is made of polished, polished, pickled, phosphated, sprayed plastic powder and high temperature baking. With the appearance of novel and beautiful appearance, it has the functions of anti-oxidation, Corrosion-resistant, high temperature, easy to clean and so on.
2, the electric furnace body adopts the international advanced air-cooled double-layer furnace structure, the effective air-cooled guide partition to make the whole shell air circulation, and finally cooling the heating element conductive sheet discharge furnace, to avoid the heating element conductive sheet High temperature oxidation; to ensure a good working environment.
3, the way to open the door for the 180-degree axial open, the door can be rotated 360 degrees to avoid the high temperature when the oven door to the inside wall to bake the arm; door lock below the door in the use of stainless steel spring lock can be effective Locking, the elasticity of the spring absorbs the phenomenon of refractory expansion, to ensure that the refractory expansion and contraction of free expansion and effective sealing.
4, the furnace shell temperature: long-term use of non-stop furnace, top and door water cooling; furnace reached the maximum temperature in the furnace temperature is close to room temperature less than 40 degrees, double-decker door insulation, fire-resistant furnace alumina alumina fiber as insulation Layer energy efficiency is honest electric stove 60%.
