VKNQ are series of high qualified heat-treating equipment. It has
been the leader of vacuum heat treatment field and has been
emdodied by the Heat Treatment Enchiridion published in China. The
main technology was imported from ALD Vacuum Technology
AG(Germany). Due to the reliable quality control and unity design,
it has been used in a very wide range, such as vacuum high-pressure
gas quenching, vacuum tempering、annealing、high temperature brazing
and sintering, as well as in heat treatment for various die &
moulds、tools and other components.
Processes Advantage :
1- High temperature uniformity and heat efficiency
2- Control the process of the temperature rising possibly
3- Convective heating by low temperature
4- Patented high-pressure gas quenching
5- Excellent cool speed and efficiency
6- Change the cycle of gas cooling
7- Isotherm quenching
8- Control the process of the cool possibly
9- Minimal rate of quenching distortion
10- Precise, reliable and human operate control system
11- Perfect security system and alarm system
12- High reliability and easy maintenance
1- Complete component parts ensure easy maintenance of the hot
zone, cooler, circulation motor within the shortest period of time
(approx. 1-2 hours)
2- No manual opening and locking of the hot zone door, resulting in
easier access to the hot zone for loading and unloading.
3- Compact vacuum furnace concept with reduced floor space
requirement. No extra electrical and mechanical assembly required.
Depending on the set-up, start-up time of one to two weeks after
delivery is possible.
4- Significant deduction of number of gas flow control flaps in the
vessel decreases the chance of problems arising and ensures better
5- Optimized vessel volume, resulting in faster evacuation and low
6- Use LEYBOLD vacuum pump and measure system as standard
7- Hot zone adopts the hard graphite felt plates covered with
graphite foil, results in bearing high temperature and erode,
prolong the use-age of hot zone and save resource.
8- Use of the heat-exchanger imported from German, large surface
cooper heat-exchanger with special finned tubes for efficient heat
exchange results in faster cooling at the same pressure.
9- Use of the circulation motor imported from France result in
speediness start, and the start current is small, without striking
10- Use of the simply-designed components results in reduced costs
for replacement parts.
11- Easy to operate on account of menu-driven programmable
