Description
Our molybdenum-made vacuum sintering
furnace is ideally suited for the debinding and sintering process of high-density
alloy, tungsten-nickel alloy, tungsten-copper alloy, titanium alloy, and metal
products sensitive to carbon atmosphere.
Characteristics
1. Design: JB4732-95, double-door horizontal structure, 20-year service
life, 6000 times of use.
2. Special debinding process
with excellent sealing structure helps avoid contaminating inside components.
3. Horizontal design for
easy loading/unloading and maintenance.
4. Automatic control of
the entire process.
5. This kind of high temperature sintering furnace adopts cyclic single-room heating mode. The whole process is automatically
controlled, monitored, and recorded by the computer.
6. Heating elements and drum
are designed with cylindrical structure, which, compared with traditional
square structure, enjoys larger loading space, more flexible dimensions and
more uniform atmosphere.
Advantages
1. Compact structure,
small occupied area, low energy consumption and rapid cooling speed, saving
energy and protecting environment.
2. Full range of sizes
available, ranging from furnaces for experimental R&D, small and
medium-sized enterprises to furnaces for mass production. We can also design high temperature sintering furnace s of other sizes according to customer’s specific requirements.
3. Round or square graphite
box is available for different applications.
4. Complete dewaxing
mode with high wax-collection rate, suitable for different forming agents
including rubber, paraffin wax, PEG and extrusion forming agents.
5. High automation level
as well as safe and reliable operating system.
6. The control system of
the molybdenum-made vacuum sintering furnace is highly-automatic and humanized with data record and
backup function.
7. The insulation box
uses “sandwich” structure and high-strength CFC material that is not prone to
deform after years of use.
8. Door of the insulation
box is designed with special “step” design for improved insulation effect and
extended service life of the insulation box.
9. Remote control,
diagnosis and repair can be realized.
10. The electrode arc
monitoring system can prevent serious damage to furnace shell caused by overheat
and arc effect.
11. The function of
resuming heating after short-time power failure can provide protection to the
product in the furnace.
12. Persistent efforts
of our R&D team in improving these high temperature
sintering furnaces have enabled Ruideer to
obtain 13 patents up till now.
