300*300*1000-10MPA sinter-HIP furnace with fully functions of
positive and negative dewaxing
Equipment system:
It mainly includes control system,heating system,vacuum
system,sinter-HIP function,cooling water system, rapid cooling
system,safety system and auxiliary system.
Design standards:
The 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:
The equipment is mainly used for vacuum sintering,pressure
sinyering,rapid cooling and so on.It can meets the strict
requirement of uniformity of furnace temperature and atmosphere in
sintering process of silicon nitride.The furnace structure design
is advanced and reasonable, easy to use 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 batch production
requirements.At the same time, the equipment meets the national
requirements for energy conservation and environmental protection.
Technical parameters of equipment:
Service life of furnace shell | 20 years |
Furnace shell design working time | 6000(furnace/time) |
Effective working zone size(W*H*L) | ≥300mm×300mm×1000mm |
Max.loading capacity | 250kg(it depends on the type of loading product) |
Max.design temperature | 1600℃ (Under the circumstance of vacuum sintering.drying furnace to
1600℃) |
Max.working temperature | 1550℃(Under vacuum and sinter-HIP status) |
Max.design pressure | 100bar |
Max.working pressure | 98bar |
Pumping speed | The vacuum degree can reach 5Pa within 30min after the pump is
started, and the ultimate vacuum value can reach 2Pa. (After drying the furnace,under the empty furnace, clean and cold
status) |
Leakage rate | ≤3pa/h (Average value within 3 hours in empty furnace, clean and cold
status) |
Fully loading cooling time | When inner furnace loaded fully material,the sintering temperature
from 1550℃ cooling to 100℃(temperature of open furnace).Cooling
time≤6h(water temperature≤26℃,95bar≤pressure≤98bar) |
Fill high pressure Argon | It adopt intermittent stable gas charging, charging time can be
set.The system accurately matches the relationship between charging
amount and time to ensure the following of gas charging. |
Pressurized time | The pressurized time to 98Bar is less than and equal 15
minutes,which can be set.(The gas resource is stable in the range
of 120bar-150bar) |
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.
