Abstract
A method and system for dispensing an additive wire involves use of a lance for delivering the additive wire and determination of location data with respect to a surface of a metallurgical melt into which the lance is placed.
Claims14
A method of dispensing an additive into a molten metal, the method comprising:
- positioning an outlet of a lance below a surface of a metallurgical melt, the positioning including determining location data relative to the surface of the metallurgical melt;
- and
- dispensing an additive wire out of the outlet while the outlet is below the surface of the metallurgical melt,
- wherein the determining of the location data includes emitting a laser beam from a distance measuring assembly toward the surface of the metallurgical melt, and the positioning of the outlet of the lance includes sending a signal from the distance measuring assembly to a displacing assembly configured to move the lance, and
- wherein the positioning of the outlet of the lance is performed in accordance with information from an encoder configured to track movement of the lance and in accordance with the location data.

A system for dispensing an additive into a molten metal, the system comprising:
- a wire feeding apparatus;
- a lance configured to receive a metallurgical wire from the wire feeding apparatus and to dispense the metallurgical wire from an outlet of the lance, the lance further configured to dispense the metallurgical wire below a surface of a metallurgical melt;
- a distance measuring device configured to determine location data relative to the surface of the metallurgical melt, the distance measuring device configured to emit a laser beam;
- a displacing assembly configured to move the lance in accordance with the location data;
- and
- an encoder configured to track movement of the lance or movement of a position actuator of the displacing assembly, and
- wherein the displacing assembly is configured to move the lance in accordance with information from the encoder and in accordance with the location data.
