Cooling of the Tuyere Belt of Horizontal Furnaces

Resumo

To reduce the rate of erosion of tuyere-zone refractories in horizontal converters and furnaces that serve as melters and converters, a study is made of the effect of the average thermal conductivity of the protective layer in front of the cooled elements on layer’s erosion rate when an explosion-proof vacuum water-cooling system is in use. Results are presented on the thermal performance of the tuyere belt and the rate of erosion of layers having different values for thermal conductivity. It is shown that erosion of the protective layer is slowed by increasing its average thermal conductivity.
