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

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
