Abstract
A method for controlling a molten metal pouring operation is disclosed which works in the presence of unusual pouring conditions such as typically encountered in aluminum casting and utilizes a laser type sensor, for example a triangulation based light section device, to monitor differences between a reference surface and the molten metal in a mold.
Claims28
A method for controlling a metal pouring operation comprising the steps of:
- sensing information relating to the height of a portion of a mold into which said metal is poured;
- sensing information relating to the height of molten metal in said mold;
- and
- using said sensed information, controlling the pouring of molten metal into said mold.
1 more element
Apparatus for controlling a metal pouring operation comprising:
- a sensor for determining information relating to the height of a mold into which said metal is poured;
- a sensor for determining information relating to the height of molten metal in said mold;
- and
- a control system using said determined information for controlling the pouring of molten metal into said mold.
1 more element
A method for controlling a metal pouring operation comprising the steps of:
- at a given point in time, at multiple positions on a surface of a molten metal being poured into a mold, sensing location information about said molten metal within said mold;
- determining from said information, the surface location of said molten metal;
- and
- using said information, controlling the pouring of molten metal into said mold.
1 more element
Apparatus for controlling a metal pouring operation comprising:
- a sensor to determine, at multiple positions on a surface of a molten metal being poured into a mold, location information about said molten metal within said mold;
- a computer, to determine from said information, the effective surface location of said molten metal;
- and
- a controller employing said determined effective surface location for controlling the pouring of molten metal into said mold.
