Ladle Refining Furnaces are used to raise the temperature and adjust the chemical composition of molten metal. Without LRFs, higher tap temperatures are normally required from steel making furnaces due to heat losses during refining with conventional ladles.

Induction hardening - Wikipedia

Process. Induction heating is a non contact heating process which uses the principle of electromagnetic induction to produce heat inside the surface layer of a work-piece. By placing a conductive material into a strong alternating magnetic field, electric current can be made to flow in the material thereby creating heat due to the I 2 R losses in the material.
