Abstract
Perfections introduced in a method of manufacturing steel, characterized in that a pair of containers (1, 2) are connected to each other by means of a conduit (5) and are used alternatively for the fusion/refining by arc and loading/preheating of scrap, being such the arrangement that while the melting/refining is carried out in a container, the hot waste gases coming from it are channeled through the conduit through the other container, to effect the preheating of the scrap load existing in it, being able to maneuver independently each of the containers for bleeding.
