Abstract

"PROCESSO PARA A DESCARBONIZAçãO PROFUNDA DE MASSAS FUNDIDAS DE AçO". Processo para a descarbonização de fundido de aço em uma instalação RH, caracterizado pelo fato de que, com o aumento do CO liberado para um receptáculo de vácuo (2) devido à descarbonização natural como resultado do oxigênio dissolvido no banho de aço e presente no sistema, uma quantidade calculada de oxigênio é introduzida, dependente no conteúdo de carbono inicial e do conteúdo de oxigênio inicial do fundido, em que uma pressão inicial para o começo do processo de sopro é calculada dependendo do conteúdo de carbono inicial."PROCESS FOR DEEP DECARBONIZATION OF ACT MASS PASTA". Process for the decarbonization of steel cast in an RH installation, characterized by the fact that as CO increases released into a vacuum receptacle (2) due to natural decarbonization as a result of dissolved oxygen in the steel bath and present in the system , a calculated amount of oxygen is introduced, dependent on the initial carbon content and the initial oxygen content of the melt, where an initial pressure for the beginning of the blowing process is calculated depending on the initial carbon content.
