Detailed explanation of vacuum furnace technology and application

1. Definition and basic structure of vacuum furnacelXiMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
lXiMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
A vacuum furnace is an industrial heating equipment that uses a vacuum system to reduce the pressure in the furnace chamber to below the standard atmospheric pressure to form a vacuum environment. Its core components include sealed furnace shell, furnace chamber, vacuum system and temperature control system, which are specifically composed as follows:lXiMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac

2. Working principle of vacuum furnacelXiMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
lXiMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
Vacuum furnace uses the dual mechanism of heat transfer of heat medium water phase change and isolation of vacuum environment to achieve efficient heating:lXiMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
lXiMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
The heat of fuel combustion is absorbed by heat medium water, and evaporates into saturated steam to complete the first phase change;lXiMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
lXiMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
Steam condenses and releases heat in the U-shaped heat exchanger, and water flows back to the evaporation chamber for recycling;lXiMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
lXiMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
The vacuum system continuously extracts non-condensable gas to ensure heat exchange efficiency.lXiMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
