Creation of High-Efficiency Promising Refractory Materials and Constructions for the Lining of Metallurgical Units

Resumo

The causes of the low level of stability of the tuyere zone of converters and the reaction zone of rotating furnaces are studied and methods of impregnating standard refractories with different binding agents and effective refractory bodies, glues, gunning bodies, and constructions of linings are developed. A construction of a plant for the fabrication of gunning bodies is proposed. On the basis of tests and the introduction of these measures, the stability of the lining of converters and rotating furnaces can be increased 1.5 – 2-fold at nonferrous metallurgical enterprises and the number of repairs and volume of losses of nonferrous metals reduced.
