Aluminium Recycling Furnace Refractories

Materials and EquipmentTest ProcedureResults and DiscussionA test apparatus was designed and constructed by the Bureau. It consisted of an electrically heated bottom loading type furnace with a 12 by 12- by 9-in stainless steel shell in which up to 16 refractory samples could be cemented in place to form a refractory-lined cavity (fig. 1). In this cavity, up to 30 lb of molten aluminum alloy was maintained at a temperature of 1,550° F. The bottom of the cavity, made of a castable refractory, had a taphole for discharging the molten metal at the end
