Title:
鋳造用静電式レベル計並びにそれを使用した鋳型への熔湯充填方法及び装置
Document Type and Number:
Japanese Patent JP4741108
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To surely control a filling level of molten metal into a cavity 5 of a casting mold 3 by precisely measuring the filling level of the molten level into the cavity 5 with high accuracy. SOLUTION: The electrostatic level meter for casting is equipped with the electrodes 6, 16 for capacitor that are installed on the surface on the casting mold 3 opposing to the cavity 5 of the casting mold 3 and the charge/discharge type capacitance gauges 13, 19 that electrically charge the electrodes 6, 16 for capacitor with a DC voltage, that discharge the charged electricity at a specific current, and that measure, through the discharging time, the electrostatic capacity obtained between the electrodes 6, 16 and the molten metal filled in the cavity 5; on the basis of the change in the electrostatic capacity measured by these charge/discharge type capacitance gauges 13, 19, the filling level is measured for the molten metal filled into the cavity 5 of the casting mold 3. Feeding is performed while the supply pattern of the driving power to an electromagnetic pump is adjusted by a controller 15 such as an SCR or an inverter.
