Different of VD VOD Vacuum Refining Furnace

VD VOD vacuum refining furnace is mainly used in high-end steel manufacturing field, with good degassing and deoxidation effect.
It creates a highly vacuum environment to achieve efficient removal of hydrogen and nitrogen in molten steel, greatly reducing the content of harmful gases in finished steel, which is crucial to improving the toughness and ductility of steel.

 

 

Features:
Working principle: By vacuuming in a closed container, the solubility of the gas is reduced, so that the gas (such as hydrogen, nitrogen and oxygen) in the molten steel can be discharged.
Deep removal of impurities: Mainly used to remove oxygen and hydrogen in molten steel, effectively reducing the impurity content.
Protective gas: Inert gases such as argon are usually used during the treatment process to prevent molten steel from contacting with air and oxidizing.

 

Function:
Improve the quality of molten steel: The impurity content of molten steel after VD treatment is reduced, which improves the toughness and strength of steel.
Improve steel performance: Enhance the performance of steel in subsequent processing, suitable for the production of high-performance steel.

 

Features:
Working principle: Similar to VD furnace, but oxygen is introduced into the furnace to remove part of the carbon content through oxidation reaction.
Decarburization effect: Mainly used in the production of high-alloy and low-alloy steel, it can effectively reduce the carbon content in molten steel.
Temperature control: The working temperature is usually high to maintain the fluidity of molten steel and promote chemical reactions.

 

Function:
Production of low-carbon steel: By removing excess carbon, the composition requirements of different steel grades are met, especially for the production of low-carbon or special steels.
Increase the yield rate: After reducing the carbon content, the performance of molten steel is enhanced, which is more in line with the needs of subsequent processing.

 

In short, VD VOD vacuum refining furnaces are two important equipment used for steel smelting and refining.
VD furnace focuses more on removing gas impurities and improving the purity and quality of molten steel.
VOD furnace reduces carbon content through oxidation reaction to produce steel with specific composition.
