1600℃ Vertical Tube Furnace

Technical Features

1 The furnace material is imported ceramic fiber, which has the advantages of balanced temperature field, low surface temperature, fast heating rate and energy saving;

2 High quality silicon carbon rod or silicon molybdenum rod is adopted for electric heating element, with high surface load and fast heating speed;

3 Stainless steel sealing flange with hinge structure is adopted at both ends of furnace body, which is convenient for operation, high temperature resistance and corrosion resistance;

4 High purity corundum tube is used as protective tube;

5 The length of the heating zone is 600 mm, and the temperature field is more uniform;

6 The vacuum degree of furnace can reach 10-3 PA with diffusion pump or molecular pump;

7 The furnace body adopts double-layer air insulation technology, equipped with automatic cooling fan to reduce the temperature of furnace shell;

8 Four universal wheels are installed on the furnace body to facilitate the overall movement;

9 The standard control system adopts domestic 30 segment program to control temperature, with temperature control accuracy of ± 1 ℃, phase-shifting trigger and silicon controlled rectifier control;

Precautions: when heating the sample and injecting protective gas, it is necessary to ensure that the inlet and outlet valves are opened at the same time to prevent the furnace tube from cracking due to excessive pressure in the protection tube;
