Matters that must be done when inert gas is used as the working process gas in a tubular furnace

Connect the working gas pipeline and connect the gas outlet end of the tube furnace to a mechanical pump. After opening the inlet valve of the tubular furnace, remember to turn on the power supply of the vacuum pump and open the outlet valve. Note: Hold the flange to avoid excessive pressure on the furnace tube, gas pipeline and evacuation of the corundum tube. When the vacuum gauge of the tube furnace reaches -0.1 (when the pointer reaches the end), close the outlet valve and close the inlet valve for operation.
First, turn the knob counterclockwise to open the main valve of the gas cylinder, then turn the knob clockwise, and slowly open the outlet pressure reducing valve until the outlet pressure is 0.004MPa (2 small grids). To do so, turn the knob counterclockwise and slowly open the inlet valve of the tube furnace; Pay close attention to the pressure gauge of the tube furnace and confirm that the pressure is below 0.08MPa (if the pressure is higher than 0.08MPa, open the outlet valve of the tube furnace to vent). These processes need to be repeated on both sides.
When the air pressure on the tube furnace pressure gauge is relatively stable, if you want to close the inlet valve of the tube furnace, please open the outlet valve, vacuum to -0.1, close the outlet valve of the tube furnace, close the mechanical pump, open the inlet valve of the tube furnace, and other operating steps.
