Abstract

A casting method includes pouring a molten metal in a ladle into a mold, analyzing at least one of a composition and a physical property of a test piece generated based on the molten metal sampled from inside the ladle, and performing appearance inspection of a casting product taken out from the mold, wherein in the performing appearance inspection, the at least one of the composition and the physical property of the test piece obtained in the analyzing is displayed on a display.

First claim

What is claimed is:

1. A casting method comprising:
pouring a molten metal in a ladle into a plurality of molds, wherein a serial mold number of each mold is associated with molten metal information corresponding to the molten metal information associated with the ladle
analyzing at least one of a composition and a physical property of a test piece and acquiring as analysis results, the test piece generated based on the molten metal sampled from inside the ladle using the pouring, wherein the molten metal information is associated with the analysis results based on the molten metal information associated with the ladle;
taking out a plurality of casting products from the plurality of molds, the plurality of casting products housed in cases, wherein the molten metal information is associated with a serial case number based on the serial mold number of each mold; and
performing an appearance inspection of the plurality of casting products within each case transported to an inspection site where a display is located, at the inspection station, wherein
the performing includes:
acquiring the molten metal information corresponding to the plurality of casting products within each case based on the serial case number;
determining the analysis results based on the molten metal information acquired; and
displaying the determined analysis results on the display during the appearance inspection.

2. The casting method according to claim 1 , further comprising:
cooling the mold, the molten metal having been poured into the mold in the pouring.

3. The casting method according to claim 2 , wherein in the performing appearance inspection, timing of the appearance inspection of the casting product and timing of displaying the at least one of the composition and the physical property of the test piece on the display are synchronized.

4. The casting method according to claim 1 , wherein in the performing appearance inspection, timing of the appearance inspection of the casting product and timing of displaying the at least one of the composition and the physical property of the test piece on the display are synchronized.
