Vacuum Degrease Furnace
I. Usage
The vacuum degreasing furnace is mainly used in metal powder products and metal injection products, including the degreasing of stainless steel
base, hard alloy, super alloy, high proportion alloy, ceramic material, magnetic material, neodymium iron boron etc. It has the advantages of
degreasing speed quickly, degreasing thoroughly and so on.
II. Feature
1. Using the high efficiency “SWEEP-GASTM” degreasing system, which have the function of deposing fat, filtrating, rough purifying, fine purifying etc.
2. It is equipped with a carrier gas degreasing system, which can strengthen the degreasing effect and make sure there are no blind angle, make
the degreasing more completely and improve the product’s quality.
3. It is equipped with a special steam washing device, which can remove the degreasing trouble.
4. The temperature and action controlling process are both automatic and the PLC achieves safety interlocking by using a computer. Which have the
functions of sound and light alarm and interlock when it’s pressure is excess, it’s temperature is excess and it’s water temperature is too high.
5. It is equipped with an internal recycle rapid cooling device and workpiece. The workpiece has efficient heat exchange technology and multi-directional blow make the cooling effectively and quickly. Comparing with the external recycle rapid cooling device, it also has the advantages of
small in size, high in starting temperature, quick in vacuum pumping speed and so on.
III. Structure
We can use either the vertical or horizontal structure according to the customer’s technical requirement. The special sealing furnace flue and
multistage watercooling laminated oil collecting machine are used for degreasing and collecting oil. The chamber can be moved out totally so
as to maintain easily. Using nickel chrome heating element, stainless steel or composite insulation panel. The heating element can be divided
into many areas, each control its temperature independently, and a programmable PID adjusts are installed. An air charging and degreasing
system is equipped which can fill the gas into the furnace, the gasification current capacity is adjustable. The internal recycling cooling system
is equipped, which can accelerate the material to cool in the furnace, reducing working period, and it’s good for improving the product quality and
the working efficiency. It is equipped with a special steam washing device, which can remove the degreasing trouble.

V. According to customer’s demand, we can update the configuration.
1. We can match a built-in fast cooling system.
2. PLC and touch screen graphics operation (touch screen)control system can be matched.
3. We can equip with a steam degreasing system.
