Abstract

LA INVENCION SE REFIERE A UN AGENTE DESULFURIZANTE PARA METAL FUNDIDO, ESPECIALMENTE ACERO PROTEGIDO, QUE CONSISTE DE PARTICULAS DE MAGNESIO RECUBIERTAS. EL OBJETO DE LA INVENCION ES EL DAR UN AGENTE DE GRAN EFECTO DESULFURIZANTE QUE NO TIENE PROBLEMAS DE HIGROSCOPICIDAD Y ABRASION Y DESGREGACION DE LOS COMPONENTES DURANTE SU ALMACENAMIENTO Y TRANSPORTE. LA INVENCION SUMINISTRA UN AGENTE DESULFURIZADOR EN FORMA DE PARTICULAS DE MAGNESIO REVESTIDAS TENIENDO UN PRIMER RECUBRIMIENTO EN CONTACTO CON EL MAGNESIO DE SILICE DE ESTRUCTURA FINAMENTE DIVIDIDA EN FORMA COLOIDAL Y/O AMORFA Y/O CRISTALINA Y/O DE VAPOR. ESTE REVESTIMIENTO ACTUA COMO AGENTE LUBRICANTE Y AGENTE DE LICUACION DE ESCORIA PARA PROXIMOS REVESTIMIENTOS. LOS SIGUIENTES REVESTIMIENTOS PUEDEN SER DE AGENTES DESULFURIZANTES DE GRAN REACTIVIDAD Y PUEDEN SER APLICADOS TAMBIEN OTROS REVESTIMIENTOS PROTECTORES Y REVESTIMIENTOS CONTENIENDO FLUJOS Y AGENTES PARA EXTRAER NITROGENO Y/O OXIGENO.THE INVENTION IS RELATED TO A DESULFURIZING AGENT FOR CAST METAL, ESPECIALLY PROTECTED STEEL, CONSISTING OF COATED MAGNESIUM PARTICLES. THE OBJECT OF THE INVENTION IS TO GIVE A GREAT DESULFURIZING EFFECT AGENT THAT DOES NOT HAVE PROBLEMS OF HYGROSCOPCITY AND ABRASION AND BREAKDOWN OF THE COMPONENTS DURING THEIR STORAGE AND TRANSPORT. THE INVENTION PROVIDES A DESULFURIZING AGENT IN THE FORM OF COATED MAGNESIUM PARTICLES HAVING A FIRST COATING IN CONTACT WITH THE SILICON MAGNESIUM OF A FINALLY DIVIDED STRUCTURE AND / OR AMORPHY AND / OR CRYSTALLINE FORM AND / OR THIS COATING WORKS AS A LUBRICATING AGENT AND SLAG LIQUIDATION AGENT FOR NEXT COATINGS. THE FOLLOWING COATINGS MAY BE FROM HIGHLY REACTIVITY DESULFURIZING AGENTS AND MAY ALSO BE APPLIED WITH OTHER PROTECTIVE COATINGS AND COATINGS CONTAINING FLOWS AND AGENTS TO REMOVE NITROGEN AND / OR OXYGEN
