Title: Method of manufacturing metal ingot
Inventor: NISHIDE DAISUKE
IPC: B22D11/18
Filed: 2011-04-07
Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a metal ingot in which, for example, the molten metal surface level of molten metal inside a mold can be monitored and the molten metal surface level height can be accurately controlled.SOLUTION: A control part of a molten metal surface level control device calculates a molten metal surface level fluctuation rate from a difference between a previous molten metal surface level height and a present bath level height, and a measuring interval, for each measuring interval from information of a molten metal surface level height obtained at prescribed measuring intervals, and further, calculates a standard deviation σn of the molten metal surface level fluctuation rate from the plurality of pieces of molten metal surface level fluctuation rate information within a prescribed period for each measuring interval. Further, at each control point, when opening of a stopper is adjusted according to the difference between the present molten metal surface level height and a reference molten metal surface level height, when the standard deviation σn is small, gain is made large, and the opening of the stopper is controlled to be large. Similarly, when the standard deviation σn is large, gain is made small, and the opening of the stopper is controlled to be small. In other words, the adjusting amount of the opening of the stopper is weighted according to the standard deviation σn.
