Talk about the specific quenching method of vacuum tube furnace

Today we will talk about the specific working methods of the vacuum tube furnace and the quenching methods used.2WEMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
Its working mode adopts pre vacuum atmosphere protection. During operation, the vacuum degree in the furnace can be pumped first, and then the high-purity nitrogen or ammonia decomposition atmosphere can be filled in for protection and heating, so as to achieve the purpose of oxidation free heating and decarburization free brightness. The mixing fan is used, which has high furnace temperature uniformity.2WEMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
The heating elements of the vacuum tube furnace are made of high-quality materials and have a long service life. They are equipped with exhaust ports and inert gas inlets. RS-485 serial port can be selected for 40 segment programmable controller model to realize computer communication.2WEMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
The heating elements of the vacuum tube furnace are located on both sides and below the furnace, and there are circulating air ducts and thermal circulating fans in the furnace. The furnace cover is automatically opened and closed, and one or two pipes can be solidified each time. Electric heating elements are used for heating, generally used for melting nonferrous metals and alloys with a melting point of about 1000 ℃. It is made of heat-resistant stainless steel. During heating and cooling, the furnace is protected by high-purity nitrogen, and the material surface is bright without oxidation. Specific quenching methods and principles are as follows:2WEMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
1、 Quenching method:2WEMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
1. Single liquid quenching: only one coolant is used for quenching workpiece in tubular heating furnace.2WEMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
2. Precooling and quenching: When quenching the workpiece in a tubular heating furnace, the workpiece shall be cooled properly before being immersed in the coolant.2WEMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
3. Double liquid quenching: the workpiece is first immersed in water for cooling, and then immersed in oil for slow cooling.2WEMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
4. Stepped quenching: the workpiece is first immersed in molten salt for cooling, and then cooled in air.2WEMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
5. Hot bath quenching: the workpiece is only immersed in high temperature nitrate or alkali for cooling, and then cooled in air.2WEMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
6. Isothermal quenching: the workpiece is immersed in the isothermal molten salt for cooling.
