Ladle Refining of liquid metal is a proven technology to produce high quality steel. Ladle Refining Furnaces (LRFs) are used to desulphurise steel, remove other impurities and hold the molten steel for casting operations. Without LRFs, higher tap temperatures are normally required from steel making furnaces due to heat losses during transfer and casting of liquid metal. LRF facilitates higher productive time to the melting furnace besides producing better quality of steel at lower cost.
By providing a mean to refine outside of the steel making furnace, LRF provides many benefits including reduced alloy consumption, uniform temperature & properties and lower energy costs. In addition, a vacuum environment can be attained in LRF, which allows production of high quality alloy steel.
Attributes
Special attributes of Electrotherm's LRF
| • |
Homogenization : Temperature and composition are equalized by stirring. |
| • |
Inclusion Flotation: Non-metallic inclusions are removed by gentle stirring of the metal. Oxygen levels of 30 particles per million (ppm) can be attained. |
| • |
Desulphurization : Desulphurization is accomplished by injection of CaSi wire and fluxes. Synthetic slag can also be used to desulphurise up to 0.015% in about forty minutes. |
