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.

There are several kinds of vacuum furnace heating way, what is commonly used?

There are several kinds of vacuum furnace heating way, what is commonly used?

Vacuum furnace is commonly used in design of high temperature thermal energy saving all metal stainless steel as a frame structure, because of the relative to the other metal heat preservation effect not only first-class stainless steel and heat insulation constant temperature is quite unique, and quick in work quickly, using insulation resistance to high temperature alloy furnace heating is very fast. So there are several kinds of vacuum furnace heating mode? Vacuum furnace heating mode according to different purposes of actually has a lot of kinds, but a way of heating "heat", is a commonly used vacuum furnace heating mode.
Vacuum furnace in the bottom of the chamber of a stove or furnace set very convenient temperature resistant plate equipment and artifacts in the heating process is not affected by temperature difference and deformation and even caused the explosion, when welding the bottom of the furnace and furnace body USES is seamless welding method, can effectively form a super vacuum mode, and when the enterprise in the production of vacuum furnace valve USES the German advanced compression techniques, reasonable to use the oven door gravity to close the valve, and using the lever principle to open the valve. On the switch link to ensure the safe and does not appear because of the heat bilges cold shrink, extrusion deformation caused by various unpredictable accidents, enterprise set up the reasonable protection valve spring buffer device.
