Recommendations on refractory practice based on years of experience that could boost furnace performance.
Melting aluminum in a reverberatory furnace involves heating the charge to melting (approx. 1220F, or 660C) and holding at molten metal temperatures to 1290F (700C). A typical furnace is heated by burners located above the molten bath line. Temperatures in the upper part of the furnace-above the molten metal bath-range from 2010 to 2370F (1100 to 1300C).
