Function Description:
Negative pressure degreasing is performed by pumping the flowmeter
into the furnace, while the spool valve is pumping, and the airflow
is used to remove the binder from the product during the
temperature rise. The vacuum is not inflated, the spool pump is
pumped, the furnace is heated, and it is sintered in a vacuum.
During the partial pressure sintering, the gas is filled to
maintain a certain pressure, the furnace body is heated, and
sintered in the partial pressure. Forced cooling is to quickly fill
the gas, the fan is turned on, the gas is circulated in the
furnace, and the heat is taken away by the cooling water.
Description:
The vacuum sintering furnace is single-chamber, horizontal and
periodic heating. It adopt low voltage and large current graphite
heating element to heating, and it has multiple heating units, each
unit controls the temperature separately. The whole process is
automatically controlled, monitored, tracked and displayed and
recorded by the computer.
It including control system, heating system, debinding system,
vacuum system, partial pressure sintering system, cooling water
system, rapid cooling system, auxiliary system and safety system.
It adopt the structure of built-in graphite liner in insulation
tube.In the mass, it can meet the strict requirements of furnace
temperature uniformity and atmosphere uniformity in the sintering
process of high performance cemented carbide.
Temperature and atmosphere uniformity:The magnetic force of the furnace control block is different from
that of the cobalt magnetic deviation.Conventional sintering
furnace test furnace control block brand isYG6 medium particles,
YC40.Debinding pressure sintering integrated.
Power supply:General standard is three phase five wire system AC380V±10%
50HZ.Control power supply:Single-phase AC210V-250V 50HZ
design(Different countries and regions can be designed according to
local grid standards)
Temperature measurement mode :WRe5-26 thermocouple
