Modelling of aluminium scrap melting in a rotary furnace ...

2006-3-1 · In a typical secondary aluminium process, the rotary furnace functions simultaneously as a smelter and a phase separator. It is capable to deal with heavily contaminated scrap (Aluminium Handbook, 2003).Fig. 1 illustrates the complex phenomena in such a furnace. The scrap feed is charged into a rotary furnace, passing through a salt layer, melting, mixing and being cleaned in the furnace.

The Tilting Rotary Process :: Total Materia Article

Tilt rotary process route: 1. Furnace is charged very quickly using the much larger charge opening. 2. Melting by double pass burner arrangement. Saving energy with faster melting. 3. The furnace is tilted to pour out the aluminum. The dry slag remains in the furnace – with no time wasted in opening tap hole.

Rotary Furnace - an overview | ScienceDirect Topics

Rotary Furnace. In rotary furnaces, the burners heat the top refractory, which rotates under the charge. Due to lower stack losses, such furnaces are more efficient than reverberatory furnaces and are used primarily to melt scrap containing less than 70% aluminum. Dross and slag may also make up

Aluminum Degassing Methods & Measurements | Modern

2015-8-15 · The ability to degas molten aluminum is generally accomplished by using a purge gas, typically introduced into the melt by a rotary degassing unit. This degassing process is limited by thermodynamic laws; when purge gas bubbles are introduced to the melt, they collect hydrogen as they float toward the surface.
