Scrap bundles and freely scattered lightweight scrap can be fed into the enclosed pre-hearth. Charging with small scrap (e.g., trim or punch scrap, chips, etc.) can occur via the charging hearth. The metal circulation between the chambers is ensured by an electromagnetic or mechanical pump, depending on the application and budget.

2. Preheating of scrap charge utilizing waste heat is becoming a regular practice with EAF (Electric Arc Furnace). Preheating is performed in charging baskets, shaft furnaces or in specially designed scrap conveyers. In the early 1990s EAFs with a direct-coupled scrap preheating function were developed.

Important aspects of operation. As liquid steel is excited by current opposite to current flowing in induction coil, it is agitated to raise its surface in the center. Surface of liquid steel is risen higher as frequency becomes lower, i.e. agitation of the liquid steel occurs stronger in low-frequency furnace than in high-frequency furnace.
