Sažetak
Since the rotating-hearth furnace in the seamless pipe rolling mill has the nominal heating capacity of 27t/h, and the real needs are of an average 13 t/h, the aim of the conducted study was to investigate whether it is possible to decreasing the height of rotating- hearth furnace workspace to reduce fuel consumption. The intensity of the charge heating depends on the radiation heat transfer from the flue gases and the lining onto the charge and the convection heat transfer from the fuel gases onto the charge. It was established with the calculations to what extent the decrease in the furnace space height affects the coefficients of heat transfer by radiation and convection, and on the other hand, the heat loss through the furnace linings on the environment. In the end of the article, the suggested solutions are explained.
