Guidelines for Handling Molten Aluminum
|Publication Date:||1 May 2016|
These Guidelines were prepared for use by all personnel concerned or associated with activities involving molten aluminum, and particularly for those involved in everyday plant operations. All major steps in remelting, treating, transferring, and casting molten aluminum and its alloys are discussed, excluding potline operations in reduction plants. Details are not given on specific operating practices for proprietary melting, melt treatment, and casting systems. For information on specific safety procedures for these systems, please consult the vendors of those systems.
Emphasis is placed on large-scale melting and casting practices for the production of process ingot. Slabs or billets produced are subsequently mechanically worked into forms such as sheet, plate, foil, forgings, or extrusions. Alternately, cast shapes such as T-bar, sow, and Remelt Scrap Ingot (RSI) may be produced and then shipped offsite for remelting at another site. Information is also provided on scrap remelting activities. Terminology used in these guidelines reflects that employed in the industry.
