The ladle refining furnace is used for refining the molten steel.The works in the ladle furnace is defined secondary metallurgy such as refining, treatment in the liquid steel ,adjustment of temperature and chemical composition.
Secondary metallurgy means economy, and quality.
The advantages of ladle furnace can be defined as follows.
| Saving of ferroalloy | Saving of energy | Increase productivity |
| Decreasing refining time from E.A.F. | Decreasing tapping temperature | Better temperature control |
| Improved inclusion, cleanless of the steel | Possibility of the analysis limited |
