Abstract
An apparatus for heat treating a metal casting having a sand core comprising sand bound by a binder, the sand core defining a cavity within the casting, an the apparatus comprising: a furnace defining a work chamber for receiving the casting therewithin; heating means for heating the work chamber such that the casting and the sand core are heated to a temperature sufficient to combust the binder of the sand core, whereby the binder is burned off, leaving only the sand of the sand core; airflow means for directing a flow of air over the casting while the casting is in the furnace so as to dislodge a portion of the sand from the casting; and means operatively associated within the work chamber for capturing portions of the sand core which become dislodged from the casting prior to the binder being combusted therefrom and for retaining the captured portions of the sand core within the work chamber until the binder has been substantially combusted therefrom.
