Abstract

abstract a method of starting a molten-bath based melting process includes establishing a sufficiently large and stable "hot zone" for ignition of oxygen and coal in a main chamber of a smelting vessel by independent means, i.e. independently of and before supplying cold oxygen and coal into the main chamber. tradução do resumo resumo patente de invenção: "inicialização de um processo de fusão". um método de inicialização de um processo de fusão baseado em banho fundido inclui o estabelecimento de uma "zona quente" suficientemente grande e estável para a ignição de oxigênio e de carvão em uma câmara principal de um recipiente de fusão por meios independentes, ou seja, independentemente de e antes de fornecer oxigênio frio e carvão para dentro da câmara principal.
