Popis: The temperature of the working surface of the refractory structure during the heat alters from 800 to 1700°C, which adversely affects the wear resistance of the refractories. Intensifying the blow through the metal, regular operation of the converters (with minimum interheat downtime), rapid charging of metal scrap in the converter, and accurate batching of the powdered materials all improve the temperature cycle of the refractory structure, and reduce its wear. During the charging of metal scrap after easting the iron in the converter, the temperature of the structure in the interheat period drops only down to 1300°C, ensuring variations in it during the heating period in the limits 1300–1700°C. Foaming of the converter batch during blow reduces the overheating of the lining. As the lining wears away the heat loss through the structure increases, which can be excluded by using heat insulation.
