VOD Ladle Refining Furnace 50ton
Function:
1. Arc heating at normal pressure, temperature measurement ans
sampling, and final temperature precise control can optimize the
pouring temperature.
2. Refining, desulfurization, deoxidation, degassing and inclusion
removal of synthetic slag.
3. Bottom blowing argon stirring makes the temperature of molten
steel uniform, the composition uniform and pure.
4. Alloy fine-tuning makes the composition control accurate, and
the final required chemical composition can be efficiently achieved
by ferroalloy elements or or aluminum or wire feeding.
5. With wire feeding machine, desulfurization and deoxidation of
molten steel can be achieved, morphological distribution of
inclusions can be changed, and alloy elements can be accurately
controlled. At the same time, the alloy yield is high, the
temperature of molten steel is low, and the environmental pollution
is small.
6. As the buffer equipment between primary smelting furnace and
continuous castingmachine, it ensures the matching production of
primary smelting furnace and continuous casting, and realizes
multi-furnace continuous casting.

Characteristic:
1. The water-cooled furnace cover is equipped with a dust removal
interface which can adjust the size of the delayed outlet, so that
the furnace can always operate in a micro-positive pressure
reducing atmosphere.
2. The copper-steel composition conductive cross arm is used to
reduce the diameter of the electrode distribution circle and
improve the service life of the furnace lining.
3. It is equipped with automatic or manual temperature measuring
and sampling device to accurately measure molten steel temperature.
4. Large cross-section water-cooled cable, compensator and
copper-steel composite conductive cross-arm are used in large
current system to reduce the main circuit impedance.
5. The automatic feeding device of alloy and slag is used to
accurately measure the alloy and slag added into the package.
6. It is equipped with PLC control system and smelting model.
Application
Ladle refining furnace belongs to the secondary refining equipment,
which typically to be used
follows the primary melting furnace. Its main function is to remove
sulfur, impurity from molten steel
and adjust chemical components, thereby, improve quality of molten
steel. LF is mainly used in
high-quality carbon steel, stainless steel, manganess steel and
other metal smelting.
