KJ-T1700-V tubular quenching furnace adopts silicon molybdenum rod as heating element, double-shell structure of vertical vacuum tubular quenching furnace, equipped with a corundum tube with a diameter of 80mm and a liquid sealed container for sample quen
(1) Double-layer shell structure, and an air cooling system is installed to make the surface temperature of the shell less than 50℃
(2) High-purity alumina fiber is used as the furnace insulation material, and the entire insulation layer is made of all-fiber material.
(3) The instrument contains a corundum furnace tube and a set of stainless steel sealing flanges (a stainless steel needle valve and a mechanical pressure gauge have been installed on it).
(4) The sealed liquid container is connected to an 80mm corundum tube through a gate valve, so that the sample falls into the liquid container without contamination.

1. Using PID method to adjust the temperature, can set 30 steps of temperature rise and fall programs.
2. Temperature control accuracy +/- 1 ℃
3. With over-temperature and burnout protection, the electric furnace heating circuit will automatically cut off when over-temperature or burnout
4. Instrument With the function of temperature self-tuning;
Material: Corundum tube OD: 80 mm; ID: 70mm; length 1000 mm The
instrument must be plugged before use to prevent heat radiation
|Vacuum sealed flanges and valves||
1. A stainless steel sealing flange, hook device, ejection port and armored thermocouple interface are installed on the top of the
furnace body ; 2. A plug-in valve and a mechanical pressure gauge are installed at the bottom of the furnace body;
3. The bottom sealing flange Air inlet
1. A stainless steel box used to hold the quenching liquid is fixed at the bottom of the furnace tube;
2. A large manual flapper valve is installed between the bottom of the furnace tube and the liquid box;
3. A maximum capacity of 1000g is installed on the top of the flange sample hanging means;
4 pushdown hanging means can be released to the quenching liquid sample cartridge;
5 must be flushed prior to argon 5PSI manually open and release the sample tube is inserted bottom
There is a set of stainless steel vacuum sealing flange in the standard configuration of the instrument, and stainless
shut-off valves are installed at both the outlet and inlet ends . Vacuum degree: 10Pa (using mechanical pump); 10-3Pa (using molecular pump)
