300*300*900-1MPA sinter-HIP furnace can be applied to sintering carbide blades, ceramic blades, extruded bar products
The main application:
For debinding of high performance cemented carbide materials; It
can realize positive pressure or negative pressure dewaxing process
(molding agent for paraffin wax or rubber), vacuum sintering,
partial pressure sintering, pressure sintering, rapid cooling and
other batch production operations and laboratory research and
development operations. Sintered carbide blades, ceramic blades,
extruded bar products and special-shaped products and other powder
metallurgy products.
General requirements
The cemented carbide pressure furnace is single-chamber,
horizontal, periodic heating, heating with low voltage and high
current graphite electric heating element, with multiple heating
units, each unit is separately controlled temperature; With
degreasing, vacuum sintering, partial pressure sintering, pressure
sintering and rapid cooling functions, the whole process by
computer automatic control, monitoring, tracking, fault
self-diagnosis simulation display and record.
Design standard: 6000 times of use, 20 years of service life,
double door horizontal structure, horizontal structure design for
easy loading and unloading and maintenance, the whole process of
automatic control.
Using the insulation tube with a built-in graphite inner liner
structure. In general, it meets the strict requirements of furnace
temperature uniformity and atmosphere uniformity in the sintering
process of high-performance cemented carbide. Furnace structure
design is advanced and reasonable, easy to operate and maintain.
The main supporting components (control components, sensors,
graphite heating element, thermocouple, main control valve, vacuum
pump, etc.) have the current international advanced level, can
adapt to the long-term, stable, reliable mass production
requirements. At the same time, the equipment should also meet the
national requirements of energy saving and environmental
protection.
Technical specifications and parameters
| Deaign operating times | 6000 furnae/time |
| Valid working zone size | 300mm×300mm×900 mm |
| Max.loading weight | 100kg |

| Heating mode | 2 zone temperature control independently |
| Heating zone temperature uniformity | Temperature uniformity at the maximum pressure (9.8bar) 1550℃ : high pressure gas is charged at the maximum allowable speed, temperature fluctuation between the set value and the measured value of the thermocouple is ≤±5℃. |
| Uniformity of atmosphere in sintering zone | Cobalt magnetic deviation range: ≤± 0.2%; Coergence force deviation range: ≤± 0.3kA /M (the temperature uniformity in the furnace is mainly measured by the furnace control plate). |
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.
