Sinter-HIP Furnace(6 MPA Sintering Furnace,Which Is Graphite-Heated
System And Designed For Cemented Carbide)
Design standard
The cemented carbide sinter-HIP furnace is a single chamber, double
door horizontal and periodic heating structure. The design is easy
to load and unload and maintain, and the whole process is
controlled automatically. Realize full load continuous operation,
300 furnace times/year or 300 working days/year. Graphite element
resistance heating (low voltage, large current); With a plurality
of heating units, each unit is independently controlled
temperature; Automatic control function, safety interlock function,
the whole process by computer automatic control, monitoring,
tracking, fault self-diagnosis simulation display and record. PLC,
industrial computer (PC) control to realize the whole process of a
key start, real-time dynamic monitoring, computer temperature,
pressure, vacuum degree and other parameters to save, safe and
reliable alarm interlock.
General requirements of the equipment
It mainly used for carbide dewaxing (vacuum AR carrier gas dewaxing
and hydrogen micro-positive pressure dewaxing), vacuum sintering,
partial pressure sintering, pressure sintering, rapid cooling and
other processes. It meets the strict requirements of furnace
temperature uniformity and atmosphere uniformity in the sintering
process of cemented carbide, and the furnace structure design is
advanced and reasonable, which is easy to use, 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 to meet the national
energy saving, environmental protection requirements.
Equipment technical parameters
| Furnace shell design service life | 20 years |
| Furnace shell design operating times | 6000 furnace/time |
| Effective working area(W*H*L) | 500mm×500mm×1800mm |
| Max.loading weight | 1500kg |
| Max.design temperature | 1600℃(Under the circumstance of vacuum sintering,heating up furnace
to 1600℃) |
| Max.working temperature | 1500℃(Under the status of vacuum and pressurization) |
| Max.design pressure | 60bar |
| Max.working pressure | 58bar |
| Pumping speed | Within 30 minutes after the pump starts, the vacuum degree can
reach 5Pa. After the pump reaches 5Pa and then pumps for 30
minutes, the ultimate vacuum value can reach 1Pa (after the oven,
in the case of cold, air and dry). |
| Leakage rate | ≤3Pa/h(Measure the ultimate vacuum after heating up the
furnace,stop the operation of the pump set and start the test.
Under the condition of empty furnace, clean, cold state, average
value within 3 hours). |
| Cooling time of full loaded | When the furnace is fully loaded with charging amount, the cooling
time of sintering temperature from 1450℃ to 100℃ is less than 6
hours (water temperature is less than 30℃,55bar is less than
58bar). |
| Filling high pressure argon gas | Adopt intermittent stable inflation, charging time can be set. The
system accurately matches the relationship between the inflating
volume and the time to ensure the inflating follow. |
| Wax yield rate | ≥98%(10Kg pure paraffin wax, argon negative pressure dewaxing.
Maximum three averages). |
| Pressurized time | Pressure to 58Bar, ≤20min can be set (the air source pressure is
stable in the range of 80bar-100bar). |
| UPS guarantee time | Power the indicator lamp and control the furnace when the power is
off, the time is ≥60 minutes. |
| Heating up speed | ≤5℃/mim(Empty furnace) |
| Heating power | About 600KVA(The power of heat transformer is related to heating up
speed). |
| Temperature control mode | 3 zone temperature control |
| The uniformity of heating area | During vacuum and pressure sintering, temperature uniformity at
pressure (58bar) 1450℃ : high pressure gas is charged at the
maximum allowable speed, temperature fluctuation ≤±5℃. |
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.
