VD VOD vacuum refining furnace are important refining equipment in the steel smelting process. They are mainly used for refining molten steel. By treating molten steel in a vacuum, the hydrogen and nitrogen content in the steel can be effectively reduced, and oxygen in the steel can be removed through carbon-oxygen reaction.
This refining furnace is widely used in steel production and can improve the purity and quality of steel.

What Is VD VOD Vacuum Refining Furnace
VD Vacuum Refining Furnaces
"Decarburization" in the VD furnace refers more to reducing gases (such as hydrogen and nitrogen) and non-metallic inclusions in the steel through vacuum treatment, and removing oxygen in the steel through carbon-oxygen reaction. At the same time, sulfur in the steel can also be removed through the full reaction of alkaline slag and molten steel.
Principle:
Using a five-stage steam jet pump to work, the vacuum chamber working vacuum reaches below 67Pa, and the refining purpose is achieved through the effect of negative pressure.
Equipment composition
The VD refining furnace includes: vacuum tank, vacuum tank cover and its tank cover lifting and moving trolley, vacuum feeding device, and control and monitoring equipment, etc.
Features & Applications
The equipment is simple, the investment is small, the operation is relatively simple, and the production cost is low.
It is widely used in steels that are not very demanding, such as carbon steel, alloy steel, ordinary bearing steel, ordinary oil pipeline steel, etc.
It can effectively reduce the hydrogen and nitrogen content in steel and improve the purity and quality of steel.
VOD Vacuum Refining Furnace
Vacuum Oxygen Decarburization Refining Furnace.
Principle:
Blow oxygen decarburization and blow argon stirring under vacuum conditions, and inject oxygen-containing gas (such as pure oxygen or air) to react chemically with impurity elements in molten steel to oxidize and generate gas, which is discharged under the action of vacuum, thereby achieving the purpose of decarburization and impurity removal.
Equipment composition
VOD refining furnace includes: vacuum tank system, vacuum pipeline system, automatic control system, oxygen system, argon system, cooling water system, vacuum pump system, etc.
Features & applications
The equipment is complex, but powerful, and can achieve efficient decarburization and impurity removal operations.
It is mainly used to produce ultra-low carbon, nitrogen stainless steel and other products to meet the needs of high-quality steel.
Through vacuum treatment, deoxidation, decarburization and mixing furnace operation, the purity and quality of molten steel are improved.
In summary, VD VOD vacuum refining furnace plays an important role in the steel smelting process. The choice of refining furnace depends on the specific production needs and steel quality requirements.
