Features：

- Tubular vacuum furnace (quartz heating furnace) is mainly used in metallurgical industry, industrial and mining enterprises, universities and research institutes for various purposes such as vacuum heating, vacuum sintering, and sintering of nano materials.

- The outer casing of the tubular vacuum furnace is made of steel coil, and the furnace is made of a high-alumina refractory material to form a porous cylinder, and an aluminum silicate fiber and an ultra-light insulation brick are used between the furnace lining and the furnace shell. The electric resistance wire is made of high-alloy electric resistance wire 0Cr25Al5, and is spirally arranged around the furnace. The lower part of the furnace body is installed with four pulleys for axial movement on the vacuum tube furnace track. A stainless steel vacuum tube is placed in the furnace, and a vacuum is taken from the front end of the vacuum tube, and the rear end is exhausted or nitrogen is introduced.

- The tubular vacuum furnace adopts double-layer shell structure and 16-stage program temperature control system, phase shift triggering and thyristor control. The furnace adopts alumina polycrystalline fiber material. The furnace has temperature field equilibrium, low surface temperature and rising and falling temperature rate. Fast, energy-saving and other advantages, is an ideal product for universities, research institutes, industrial and mining enterprises to do powder, ceramic sintering, high temperature experiments, quality testing. Unique furnace design, side opening door, from left to right, the furnace door can be remarkable and durable; the temperature controller is a double-row LED display dial, mainly used for temperature control, high temperature control accuracy (plus or minus 1 degree), reaction Sensitive, programmable PID control, with deviation, over-temperature alarm and power-off protection, safe and reliable operation.
