Abstract

processo para equilibrar um fluxo de aço líquido em uma lingoteira e sistema de lingotamento contínuo de aço líquido. este processo para equilibrar um fluxo de aço líquido em uma lingoteira, em que o aço é introduzido na lingoteira (12) a partir de um repartidor através de um bocal de proteção que se abre abaixo do nível de aço na lingoteira, compreende as seguintes etapas: a) aquisição de um conjunto de características de fluxo na lingoteira, b) comparação das características do fluxo adquirido na etapa anterior com um modelo predefinido e determinar as ações de ajuste a serem tomadas para equilibrar o fluxo, e c) ajuste do fluxo.process for balancing a flow of liquid steel in an ingot mold and continuous liquid steel casting system. this process for balancing a flow of liquid steel in an ingot mold, wherein the steel is introduced into the ingot mold (12) from a tundish through a protective nozzle that opens below the level of steel in the ingot mold, comprises the following steps : a) acquisition of a set of flow characteristics in the ingot mold, b) comparing the flow characteristics acquired in the previous step with a predefined model and determining the adjustment actions to be taken to balance the flow, and c) adjustment of the flow.
