Abstract: The method and apparatus for reclaiming substantially pure sand from a heat treating furnace; wherein a casting with sand core and/or sand mold, comprising sand bound by a combustible binder, attached thereto is introduced into the heat treating furnace; or, wherein portions of sand core and/or sand mold that are not attached to a casting are introduced into the heat treating furnace. Wherein, the reclaiming within the furnace is carried out, in part, by a fluidizer that promotes binder combustion by one or more process of agitating, heating, and oxygenating. Wherein, the characteristics of the reclaimed sand are selectively controlled by controlling the dwell time of the sand within the heat treating furnace.

Abstract: An integrated metal processing facility in which molten metal is poured into a series of molds at a pouring station to form metal castings, which are then transferred to a heat treatment line. Prior to introduction of the castings into a heat treatment station of the heat treatment line, the castings are subjected to heating sufficient to arrest cooling of the castings at or above a process control temperature for the metal thereof.

Abstract: A system and method for heat treating castings and removing sand cores therefrom. The castings are initially located in indexed positions with their x, y, and z coordinates known. The castings are passed through a heat treatment station typically having a series of nozzles mounted in preset positions corresponding to the known indexed positions of the castings passing through the heat treatment station. The nozzles apply heat to the castings for heat treating the castings and dislodging the sand cores for removal from the castings.
