Document Type and Number:
Japanese Patent JP2849213
Kind Code:
B2
Abstract:
The method and apparatus for reclaiming substantially pure sand from a heat treating furnace (19); 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 (19); or, wherein portions of sand core and/or sand mold that are not attached to a casting are introduced into the heat treating furnace (19). Wherein, the reclaiming within the furnace (19) is carried out, in part, by a fluidizer (40) that promotes binder combustion by one or more processes of agitating, heating, and oxygenating. Wherein the characteristics of the reclaimed sand (25) are selectively controlled by controlling the dwell time of the sand (25) within the heat treating furnace (19).
