LF Series Molten Steel Refining Ladle Refining Furnaces Complete Plant
Ladle refining furnace application to the whole enterprise, at
least can increase the following benefits: speed up the pace of
production, improve the entire metallurgical production
efficiency.Application: Ladle refining furnace is widely used in
industry, iron and steel, metallurgy and other industries.
Main functions:
| 1. | Heating and heat preservation function of liquid steel.New heat
energy can be obtained from molten steel by arc heating, which not
only makes it possible to add alloys and adjust the composition of
the ladle, but also makes it possible to add slag to facilitate
deep desulfurization and deoxidation of molten steel.Moreover, the
starting temperature of molten steel required by continuous casting
is guaranteed, which is beneficial to the improvement of billet
quality.
|
| 2. | Argon stirring function.Argon is blown into the deflected steel at
the bottom of the ladle to obtain certain stirring function.
|
| 3. | Vacuum degassing energy.At the same time, argon gas is blown into
the bottom of the ladle to agitate the molten steel. The hydrogen
and nitrogen contents in the molten steel can be removed, and the
oxygen and sulfur contents can be further reduced. Finally, the
liquid steel with high purity and superior performance can be
obtained.

Characteristics
1. Adopting the water cooled furnace roof equipped with dedusting
interface of which the size of smoke outlet is adjustable to keep
the tiny barotropic atmosphere and reducing atmosphere inside the
furnace.
2. Using the cooper-steel composited conductive arm, reducing
electrode pitch circle diameter and prolonging lining service life.
3. Equipped with automatic or manual temperature measurement and
sampling device to measure the liquid steel temperature accurately.
4. Large current system adopts large-section water cooled cable,
compensators and copper-steel composite conducive arm, thus reduce
major loop impedance.
5. Using alloy and slag automatic charging device to accurately
measure the charging volume.
6. Equipped with PLC control system and smelting model.
