Abstract

resumo patente de invenção: "início de um processo de fundição". a presente invenção refere-se a um método de início de um processo à base de banho em fusão para fundir um material metalífero. o método inclui usar o fluxo de calor de elementos resfriados por água em partes inferiores de um recipiente de fundição para fornecer uma indicação de temperatura de banho em fusão durante pelo menos uma parte precedente do método de início e ajustar as taxas de injeção de gás contendo oxigênio e/ou material carbonáceo no recipiente de fundição para controlar a temperatura de banho em fusão durante o início sem exceder os níveis de fluxo de calor crítico e interrompem o método de início. 25/25 23579349v1 4/4 1/1
