Operation steps of tube furnace

1. Place the furnace tube symmetrically in the center of the furnace, place the sample in the center of the furnace tube, place the pipe plugs at both ends of the furnace, and assemble in the order of the inner flange sleeve, sealing ring, pressure ring, sealing ring, and outer flange sleeve. OK, tighten the 3 hexagonal screws evenly in multiple times to ensure that the flange is not deflected.

2. To open the gas circuit of the tube furnace, the main valve of the gas cylinder, the pressure divider valve, and the pipeline switch should be opened in sequence, and closed in the opposite direction when it is closed.

3. Connect the gas path in the order of the inlet pipe, inlet valve, outlet valve, and safety bottle, and adjust the gas flow rate through the inlet valve and gas path switch. Generally, one continuous bubble in the safety bottle shall prevail.

4. Turn on the air switch, turn on the power button, enter the program temperature setting, press the heating button, and start working.
