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.
