TILTING ROTARY FURNACE PROCESS
Rotary Furnace Process applied in the Aluminum Recycling industry is generally a type of rotary kiln that can be tilted and rotated under the salt flux (cover flux), which has a relatively low amount of metallic aluminum and has high salt impurities and contaminations such as non-metallic, volatile organic components. It is the process of melting with high efficiency.
It will be more descriptive to choose rotary kilns as a kind of incinerator, in the selection of raw materials to be chosen. Rotary Furnace Process; It is a dry process, before the aluminum raw material is melted and bathed, the impurities on it are burned with an open flame, the raw material continues to be charged and after the same processes are applied to all charges, the coating, oil, VOC etc. is reached. Works on the principle of melting and transferring the raw material purified from impurities such as.
The mixture of NaCl (Salt) + KCl (Potassium Chloride) + Cryolite (Na3AlF6) or Calcium Fluoride (CaF2), which are generally used in this melting phase, mainly serves as cover flux and reduces metal loss as a result of oxidation by cutting aluminum contact with air.
Types of aluminum raw materials that can be melted in a Rotary Furnace;
Aluminum Hard Scrap (Sump, Aluminum Casting Scrap)
Aluminum Profile Scrap (Pressed and / or open)
Aluminum Soft Scrap
Aluminum Beverage Can Scrap (UBC)
Aluminum Chip Scrap (With Press and / or Briquettes)
Aluminum Wheel Scrap
Aluminum Slag and Ramat
Recycled Aluminum Material (Incinerated)
All Mixed Aluminum Scrap and Manufacturing Waste (Araiş)
The table containing the production capacity and energy consumption values according to the capacities of the rotary kilns is as follows;
