Abstract
UN METODO PARA EL TRATAMIENTO TERMICO DE ACERO, SOBRE TODO DE UN MATERIAL DE ACERO TIPO TIRA O TIPO VARILLA, TAL COMO UNA TIRA DE ACERO, UNA HOJA DE ACERO, UNA VARILLA DE ACERO O UN ALAMBRE DE ACERO QUE SE HAN LAMINADO Y CALENTADO EN UN HORNO O CRISOL A UNA TEMPERATURA SUPERFICIAL DE 900 (GRADOS) C APROXIMADAMENTE Y REFRIGERADO POSTERIORMENTE Y OPCIONALMENTE TRATADO EN UNA BAÑO DE ELECTROLITOS Y/O BAÑO DE ACIDOS. LA INVENCION SE CARACTERIZA PORQUE LOS QUEMADORES DEL HORNO SE ENCIENDEN CON UN COMBUSTIBLE LIQUIDO O UNO GASEOSO QUE SE QUEMA CON LA AYUDA DE UN GAS QUE CONTIENE AL MENOS UN 85 % EN VOLUMEN DE OXIGENO Y COMO MUCHO UN 10 % EN VOLUMEN DE NITROGENO.
