Resumo

Estuda-se pela modelagem física a influência de fatores geométricos e operacionais sobre o processo de mistura, velocidade de desgaseificação e taxa de ejeção de líquido em um reator de sopro combinado. Analisa-se a importância relativa do posicionamento das ventaneiras, e do padrão de sopro (distância lança-banho, vazão pela lança e vazão pelas ventaneiras) tendo por base um reator industrial de 80 toneladas.

Palavras-chave

Misturas, Desgaseificação, Projeções, Convertedor LD

Abstract

Physical modeling is employed in order to assess the influence of some geometrical and operational parameters of a combined blow converter on mixing, degasification and rate of projections. The relative role of bottom tuyeres location and blow pattern (top gas blowing rate, tuyeres blowing rate and lance to bath distance) has been clarified. Operational data have been taken from a 80 tons reactor.

Keywords
