Vacuum Compression Furnace For Tungsten Carbide Inserts, Cutting
ToolsThe cemented carbide pressure 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 (IPC) 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. The equipment can be used for dewaxing of cemented carbide (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
requirement of uniformity of furnace temperature and atmosphere in
sintering process of cemented carbide. Service life | 6000times / 20-years service life | Useful space | ≥300×300×600mm | Max.
