300*300*600 Vacuum Sintering Furnace for alloy powder materials
Equipment system:
It mainly includes control system, heating system, positive and
negative pressure,vacuum system, pressure sintering system, cooling
water system, rapid cooling system, safety system and auxiliary
system.
Design standards:
The vacuum sintering 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:
It is mainly used for vacuum sintering, partial pressure sintering
(static, dynamic), vacuum cooling, rapid cooling and other
processes of powder material, ceramic material, wear-resistant
material and high temperature alloy.It can meet the strict
requirements for the uniformity of furnace temperature and
atmosphere in the sintering process, and the furnace body 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
Available working zone size(W*H*L) | 300mm×300mm×600mm |
Max.loading weight | 100kg(The amount of load depends on the type of product) |
Working temperature | 850℃(maximum working temperature) |
800℃(actual working temperature ) |
Pumping speed | The vacuum degree can reach 5Pa within 30min after the pump is
started, and the limit vacuum value can reach 1Pa after pumping for
30min after reaching 5Pa (After drying the furnace,under the empty furnace, clean and cold
state.) |
Leakage rate | ≤3Pa/h (Measuring the limit vacuum after drying the furnace, stop the
operation of the pump group and start the test.Average within 3
hours in empty furnace, clean and cold state) |
Cooling speed
| Empty furnace,the cooling time of cooling temperature from 800℃
down to 100℃ just cost less or equal 3 hours.(water
temperature≤28℃,2bar≤water pressure≤3bar) |
Cooling speed | The inner furnace is equipped with rapid cooling fan and cooling
water realize rapid cooling. |
Heat rod material | Graphite |
Temperature control mode | Three zone temperature control independently |
Heating up speed |
Empty furnace heating up≤5℃
|
Heating power
| It is about 120KVA (the power configuration of the heating
transformer is related to the heating speed, and the heating power
can be automatically limited according to the actual use of the
production). |
Uninterrupted power supply guarantee time
| It can power the indicator lights and control the furnace when the
power goes out,the time is more than or equal 80 minutes. |
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 commissioning,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.
