Abstract

INICIAÇÃO DE UM PROCESSO DE FUNDIÇÃO. A presente invenção refere-se a um método de iniciação de um processo de fundição à base de banho de material fundido que inclui começar o abastecimento de gás contendo oxigênio frio e material carbonáceo frio em uma câmara principal de um vaso de fundição dentro de no máximo 3 horas após a conclusão de uma carga de metal quente no vaso e inflamar o material carbonáceo e aquecer a câmara principal e o metal fundido na câmara principal.
