The development of an intelligent system for automatic powder additions to the continuous casting mould
The objective of this project was to develop the technique, operational concepts and the type of equipment necessary for the automatic and intelligent dispensing of powder to a continuous casting mould. A system was developed using a robotised lorry loader arm for scanning the mould, an infra-red sensor for measurement of powder surface temperature and a screw feeder system for conveying powder into the model mould. A series of setpoints was taught to the robot to allow full coverage of a full-scale mould. The number of paths along the mould was determined by the sensor spot size of the infra-red detector. The presence of the submerged entry nozzle (SEN) was allowed for by retracting the arm and slewing around it. An adaptive path sequence was developed for which the sequence of paths over the mould was varied depending on the frequency and position of powder deposits during the previous sequence. Powder additions were triggered by the presence of hot spots in the mould, the arm stopping whilst additions were made.
