Abstract

Scrap metal for steelmaking in a converter is preheated by a heating installation and subsequently charged into a charging trough. The preheating takes place in a separate furnace which is aligned parallel to the charging trough. The furnace can be brought to an emptying position in such a way that the preheated scrap can fall from the preheating furnace and still retain its orientation.
