Effect of Operational Factors on Steel-Teeming Ladle Lining Working Layer Life

Resumo

Reasons are considered for crack formation in periclase-carbon, aluminopericlase-carbon and spinel-periclase-carbon refractories, and also partial effect on life of flux-cored wire and inert gas blowing intensity in enterprises smelting low-alloy, carbon, and low-silicon materials. The turnover of a steel-teeming ladle is more than 4 – 5 melts/day: the proportion of melts treated in FLU is 100%; open stream casting into a CBCM. Defining factors and the proportion of their effect on steel-teeming ladle life are evaluated from the results of this work.
