Abstract
A method of monitoring the mold geometry during the continuous casting of billets and blooms formed of steel. During the progress of the continuous casting operation there is measured the actual value of the withdrawal of heat at the continuous casting mold and this value is compared with a set or reference value. In the presence of a deviation exceeding a predetermined magnitude there is determined a damaging mold geometry.
Claims5
A method for monitoring the geometry of a mold during the continuous casting of steel strands, for instance billets and blooms, and replacing a detected damaged mold, comprising the steps of:
- during the continuous casting operation determining an actual value of the withdrawal of heat from the continuous casting mold;
- comparing such actual value with a predetermined reference value which is set as a function of the carbon content of the cast steel and the residence time of the cast steel within the mold;
- upon deviation of the actual value from such reference value by a predetermined amount determining a damaging change in the geometry of the continuous casting mold;
- and
- exchanging the continuous casting mold when the determined damaging change requires utilization of a different continuous casting mold for further casting operations.
