METHOD FOR MANAGING THE CHARGE IN A MELTING FURNACE AND CORRESPONDING LOADING APPARATUS

摘要

Method for managing the metal charge in a melting furnace comprising at least a step of depositing metal materials to be melted in a storage zone, a step of picking up and loading the metal materials from the storage zone onto feed means by means of loading means, and a feed step in which the feed means feed the materials toward the melting furnace. The deposit step provides to divide the storage zone into a plurality of specialized areas in each of which a differentiated type of the metal materials is deposited, and during the pick-up and loading step, a processing device controls and commands the actuation of the loading means which pick up the types of materials from the specialized areas and load them onto the feed means according to a desired modality and quantity.

1. Method for managing the metal charge (11) in a melting furnace (14) comprising at least a step of depositing a plurality of differentiated types of metal materials in a storage zone (13), said differentiated types comprising at least low value scrap, scrap with a greater value, slabs of cast iron or other, a step of picking up and loading said metal materials from said storage zone (13) onto feed means (12) by means of loading means (19-22), and a feed step in which said feed means (12) unload said materials into the melting furnace (14), characterized in that said deposit step provides to divide said storage zone (13) into a plurality of distinct and specialized areas (33-40) in each of which a different type of materials (23-30) of said metal materials is deposited, each of said specialized areas (33-40) being codified depending on the type of metal materials deposited therein and containing metal materials with homogeneous characteristics, in that at least its own distinct loading mean (19-22) is associated to each of said specialized areas (33-40), and in that during said pick-up and loading step, a processing device (50) controls and commands the actuation of one or more of said specific loading means (19-22) which pick up selected types of materials (23-30) from one and/or another of said specialized areas (33-40) in relation to the final metallurgical properties of the product to be obtained and in relation to an optimization of the energy consumption required to set off the melting process and load them onto said feed means (12).
