The type of a rotary furnace is often used in secondary aluminium processes. The furnace is charged with the scrap feed, which rotates to be melted under a salt layer. The furnace drum rotation enables more effective heat transfer from the hot refrac

Steel and iron making industries have been driven by the requirements of maintaining or improving product quality and minimization of production costs. Within these requirements the overall energy management and energy efficiency play important role.
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 hei

Energetska učinkovitost ljevaoničkih peći za taljenje aluminija je znatno niža u odnosu na većinu drugih pećnih agregata, poglavito zbog niskog emisijskog faktora aluminija kao i slabe vodljivosti topline rastaljenog aluminija te niskog emisijs

The Ability to Increase the Furnace Energy Efficiency by Increasing the Temperature of Preheated Air
Energy efficiency of a reheating furnace for charge heating prior to hot forming depends on various parameters of the heating process. The greatest influence on the furnace energy efficiency has the mode of realization of the combustion process. The
