PROBLEM TO BE SOLVED: To provide a solution treatment furnace that enables regeneration of core sand through the use of heat on heat treatment, while tar caused by burning of an organic binder is removed at the same time as an aluminum casting is subjected to solution treatment.SOLUTION: A solution treatment furnace, in which an aluminum casting cast by a die provided with a sand core is subjected to solution treatment, includes: a first heat treating furnace having an inlet to which a casting before shakeout after casting is input; a second heat treating furnace having an outlet; a shutter provided between the first heat treating furnace and the second treating furnace; a conveyer for casting transportation that transports the casting from the inlet to the outlet; and a conveyer for sand transportation provided under the conveyer for casting transportation in the first heat treating furnace. The conveyer for casting transportation is configured to have a mesh structure on a surface where the casting is placed, and causes the core sand when the sand core is collapsed to pass through downward and then fall onto the conveyer for sand transportation. |
