Design standards
The precision ceramics sinter-HIP furnace is a single chamber and
double door horizontal and periodic heating structure,which is
designed for easy handling and maintenance, the whole process is
controlled automatically.It can realize full load continuous
operation, 300 furnace times/year or 300 working days/year.It uses
graphite element resistance heating (low voltage, high current) .In
addition, there are multiple heating units, each of which controls
the temperature separately.It equipped with fully automatic control
function and safety interlock function.The whole process is
automatically controlled, monitored, tracked and recorded by
computer.The PLC, industrial computer (PC) control to realize the
whole process of one-key start, real-time dynamic monitoring,
computer will save temperature, pressure, vacuum and other
parameters ,alarm interlocking is safe and reliable.
General equipment requirements
Mainly used in precision ceramics dewaxing (Ar carrier gas dewaxing
and hydrogen micro-positive pressure dewaxing), vacuum sintering,
partial pressure sintering (static, dynamic), pressure sintering,
rapid cooling and other processes.It meets the strict requirements
of the uniformity of furnace temperature and atmosphere in the
sintering process of cemented carbide, and the furnace structure
design is advanced and reasonable, which is convenient for
operation and maintenance.The main supporting components (control
components, sensors, graphite heating element, thermocouple, main
control valve, vacuum pump, etc.) have the international advanced
level, can adapt to the long-term, stable, reliable mass production
requirements.At the same time, the equipment meets the national
requirements of energy conservation and environmental protection.
Technical parameters of equipment
Furnace shell design service | 20 years |
Furnace shell design operating time | 6000 furnace/times |
Valid working zone size(W*H*L) | ≥500mm×500mm×1200mm |
| Maximum loading capacity | 1200kg (The load is dependent on the product type) |
Maximum design temperature | 2100℃ ( Heating up the furnace up to 2100℃ under vacuum sintering
condition) |
Maximum working temperature | 2000℃ (Under vacuum and pressurization condition) |
| Maximum design pressure | 64bar |
| Maximum working pressure | 58bar |
Pumping speed | The vacuum degree can reach 5Pa within 30min after starting the
pump.The ultimate vacuum value reaches 1Pa after reaching 5Pa and
pumping for 30min (after drying, cold, empty, dry). |
Leakage rate | ≤3Pa/h (stop the pump group operation and start the test after the
limit vacuum is measured after the oven, .Empty furnace, clean,
cold state, within 3 hours average value). |
Full furnace loading cooling time
| When the inner furnace fully load materials,the cooling time of
sintering temperature from 1450℃ to 100℃ is ≤6h(water
temperature≤26℃,55bar≤pressure≤58bar) |
Filling high pressure argon | Intermittent stable charging is adopted, charging time can be
set.The system accurately matches the relationship between charging
amount and time to ensure the following of charging. |
Wax collect rate | ≥98%(10Kg pure paraffin, argon negative pressure dewaxing.Maximum
three mean values). |
Pressurized time | The time of pressurization to 58Bar is ≤15min, which can be set
(the gas source pressure is stable within the range of 80-100bar). |
Uninterrupted power supply guarantee time
| Power the indicator light and control the furnace during power off
for more than 80 minutes. |
Heating up speed | ≤5℃/min(Under the condition of empty furnace) |
Heating power | About 320KVA |
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
