Vacuum pressure sintering furnace for cemented carbide research
Main application
For dewaxing of high-performance cemented carbide material(It can realize vacuum dewaxing),It apply to research for lab and mass production for factory of vacuum sintering ,partial pressure sintering,gas pressure sintering
General description
This kind of vacuum pressure sintering furnace for cemented carbide research, which is single room,horizontal type,recycle heating furnace,it adopt graphite heating element of low voltage and large current .All the technical process is automatic controlled,monitored,chased,fault diagnosed which showed and recorded by computer.
Design standard:JB4732-95,20-year service life,double doors horizontal structure,6000 times.
Horizontal design for easy loading/unloading and easy maintenance.
Automatic control of the entire process
This kind of sinter-HIP furnace for cemented carbide production,it includes control system,heating system,dewaxing system,vacuum system,partial pressure sintering system,gas pressure sintering system,rapid cooling system,Assist System ,Security System.
Furnace heating element, insulation and charging box are all in cylindrical structure, compared with the traditional square structure:Charging room is larger, size is more flexible, the temperature and atmosphere more uniform.

After sales:
1.Installation, Commissioning And Acceptance
We do installation, commissioning and acceptance in buyer's plant.During the installation and commissioning period, the commissioning personnel shall be provided free of charge by the demander according to the staff standard.
The equipment shipped to the buyer, the seller received the buyer's notification, both within a week to carry the equipment out of the box together, then check the equipment and all components according to the packing list . Including equipment accessories, spare parts and special tools, attached manual and technical documents, etc. It can be installed after the acceptance check of equipment.
After installation and debugging, the equipment shall be accepted according to the technical accessories.
2.Training
When taking-over the Furnace to the customer, We will give a staff training to customer. The operating personnel of the customer should join to commission,test the furnace, when installing at customer’s company.
This is practical operation training and practical maintenance training,
and our technical personnel will telling the basic principle,equipment maintenance knowledge,And the common fault handling measures.We can training 2 ~ 3 workers. ( Training how to maintenance and operating.)
3. Warranty period
The warranty period of the equipment is 12 months, which starts from the date of installation and debugging of the supplier. Equipment failure happens, after-sales service personnel shall give solutions within 2 hours, after receiving the buyer's notification . If it is need to go to the site for treatment , operators dispatched by seller should arrive at the site within 48 hours after go aboard. In case of emergency,operators should arrive at the site within 48 hours after go aboard, and continue to make repairs until the fault is removed and the equipment returns to normal.
