Abstract (en)
The device comprises a sand mold (1) with an inner cavity (2) fillable with a metallic alloy to be solidified inside the inner cavity, thermal energy extracting means (3) embedded at least partially in the sand mold (1) and comprising at least a conduct (32) and a coolant inside the conduct (32), movable in the conducts for extracting heat from the metallic alloy. A method is proposed comprising the steps of providing a sand mold comprising an inner cavity (2), providing thermal energy extracting means (3), the thermal energy extracting means (3) comprising at least a conduct (32),placing the thermal energy extracting means at least partially embedded in the sand mold (1), filling the inner cavity (2) with a metallic alloy to be solidified inside the inner cavity and circulating a coolant inside the conduct (32) for extracting heat from the metallic alloy.
