Abstract
An installation for the production of liquid metal by melting a charge of ferrous material, comprising at least one electric melting furnace consisting of a chamber closed by a removable roof and associated with consumable electrodes for melting the charge of ferrous material, at least one chamber for preheating the charge, and a main hot gas and flue gas removal circuit, equipped with a filtration device for removing pollutants. The preheating chamber is associated with one or more burners, and the gases produced in the chamber during preheating are sent to an auxiliary low-throughput treatment circuit equipped with an incineration chamber, and the flue gases produced in the furnace by the melting of the charge are sent directly to the main treatment circuit.
