Vacuum furnace operation method

Vacuum furnace operation method

A, preparation,
First turn on the cold water machine, vacuum furnace may alarm because of the water pressure is too low.
Second, turn the power switch
Before electricity, be sure to carefully check the status of each switch:
1, the heating way should be put in "manual", counterclockwise to the end for power regulation can be;
2, pressure lowered a stop "toggle switch, if there is any check its in stop position, pressurized potentiometer have the knob to the minimum.
After the above checks are no errors. To open the main power switch. Then open the power switch.
Third, furnace into the sample
Normally the stove when not in use are under vacuum condition, so before use to check the stove is under vacuum, first using the inlet valve of furnace gas has been slowly to the atmospheric pressure, and then turn on the furnace cover with a jack and removed the lid and put in the sample that need to burn. If you don't need to pressure sintering, then be sure to remember to cover the inside and outside the two layers of insulation cover, otherwise, the temperature may rise will not come up. If want to undertake heating sintering, then must make the most out of insulation cover in the middle of the small cover off to start testing. Note: when put the sample must not touch the heating element, prevent short circuit occur furnace shell and the heating element.
Vacuum furnace features:
1 low processing temperature, vacuum furnace, the workpiece is not easy to deformation.
2, vacuum furnace can process carbon steel, cast iron, steel, low alloy steel, stainless steel and other materials.
3, vacuum furnace, can improve the strength, corrosion resistance and abrasion resistance.
