Inventor: OKUNO KEIGO
IPC: B22D11/16
Filed: 1984-03-19
Abstract: PURPOSE:To enable improvement in the yield of a product by determining the length of the final shrinkage hole from the shrinkage rate of a billet on solidification calculated from casting conditions at the end period of casting, subtracting said length from the length of the final billet and determining the cutting length of the effective billet.
