IPC: B22D17/32
Filed: 2006-11-30
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for measuring the size of splashes of molten metal, which method can properly measure the size of splashes of the molten metal and can improve productivity.  <P>SOLUTION: The moving time ΔT1 of splash between sensors is obtained from the time T21 at which the splash has arrived at a second optical sensor 20B and the time T11 at which the splash has arrived at a first optical sensor 20A. The speed V of the splash is calculated applying a known sensor distance L to the moving time ΔT1. The passing time (splash optical sensor passing time) ΔT2 of the splash 16F with respect to the first optical sensor 20A is obtained by subtracting the arrival time T11 to the first optical sensor 20A from the passing time T12 of the splash 16F with respect to the first optical sensor 20A. The size (s) of the splash is obtained based on the following relational expression [D+s=V*ΔT2] (wherein D is the size of an optical sensor light detecting region; V is the speed of the splash; and ΔT2 is the passing time). When the size (s) of the splash is not larger than a threshold value for closing a pressure reducing valve, the pressure reducing valve is closed and the intrusion of the splash through the pressure reducing valve is prevented so as to avoid the interruption of production, thereby to improve the productivity.  <P>COPYRIGHT: (C)2008,JPO&INPIT
