Product description
Product parameters

  basic introduction

  The open vertical vacuum tube furnace has a small body and a very rapid heating rate (the fastest can reach 50 ° C / min). It can not only be evacuated but also protected by gas. Its structure makes the disassembly and assembly of the furnace tube convenient and the operation simple and convenient. The user can directly move the sealed cavity out of the furnace body to speed up the cooling process. The transparent quartz tube cavity can intuitively see the sample sintering state. The furnace tube workpiece traverses the furnace with the imported resistance wire, the temperature field is uniform, and the temperature difference between inside and outside can be controlled at about 3 degrees. It is a high-speed temperature rise furnace with extremely high cost performance.

The sample is burned on the upper flange. After the furnace body is heated to the target temperature, the furnace body is driven to slide down to the sample by the motor.


  main feature

1、The thermal insulation material adopts the inorganic material of alumina fiber formed by vacuum adsorption, which is environmentally friendly and energy saving, free of dirt, clean and beautiful;

2. Using fuzzy PID control, intelligent PID precise control, uniform temperature field, consistency of sintered products;
3. The furnace body adopts double-layer air cooling mechanism. When the furnace is burned to the highest temperature, the surface temperature of the shell is lower than 60 degrees

sealing system

The upper end of the furnace tube is equipped with a stainless steel sealing flange (including precision needle valve, pointer vacuum pressure gauge and double ferrule gas nozzle connector) and can pass gas; the lower end of the furnace tube is a standard quartz frosted connector, which can be directly connected to the U-shaped tube below Docking. Ensure the tightness of the entire experiment.
