POURING CONTROL DEVICE IN POURING FURNACE FOR LIGHT METAL CASTING

摘要

PURPOSE: To improve pouring precision and make easy the adjustment of molten metal level and its changing by preventing not to deviate molten metal level control range from the initial setting value and improving constant molten metal level control. ;CONSTITUTION: A holding chamber 2, control chamber 3 and discharging chamber 4 are provided in the pouring furnace 1 holding the molten light metal alloy of a specific temp., the molten metal level detecting means consisting of a non-contact sensor of ultra sonic sensor 13, etc., is placed above molten metal level in the control chamber 3 opened to the atmosphere, the pressurizing force in the holding chamber 2 is adjusted in response with an output signal of the sensor 13, after a molten metal level L is held in the setting range as balanced, the molten metal is poured to a casting machine from the discharging chamber 4.;COPYRIGHT: (C)1995,JPO
