PROCESS FOR MELTING METAL OR NON METAL MATERIALS

摘要

The process is characterized by a step of addition of a material, which includes at least one polymer originating from hydrocarbon, to the batch to be melted; conveniently, said step occurs immediately before igniting the burner. The added material may also comprise fossil fuels and metal and non metal alloys; preferably said polymer comprises polyethylene, polypropylene or polystyrene without foaming or a combination thereof. The utilisation of a material which comprises at least a polymer originating from a hydrocarbon in a metal or non metal melting process has the effect of enhancing the thermal efficiency and/or inhibiting the oxidation of the elements comprising the batch to be melted.
