Abstract:

In a melt shop plant, the vessel shell deformation in LD converters can have a significant influence on the laser measurement of the refractory. Accurate measurement is crucial to ensure operational safety, efficiency, and the quality of the steel production process. The combined blowing through the tuyeres increases the agitation of the metal bath, reducing areas of chemical stagnation, favoring dephosphoration, increasing the manganese content and reducing iron in the slag. With the improvement of refining conditions, there is an increase in the metallic yield, a reduction in the consumption of fluxes and an increase in the life of the refractory. However, the vessel shell deformation can distort the tuyeres measurements obtained by means of laser measuring devices can also affect the position and orientation of the reference points used for the measurement of the refractory resulting in variations in the distance between the laser measuring device and the surface of the refractory. This may lead to measurement errors, resulting in inaccurate or inconsistent measurements. To mitigate the effects of the deformation of the shell of the LD converters in the laser measurement of the refractory, a manual measurement of the wear profile of the tuyeres was performed after the end of the BOF post-BOF campaign, this was facilitated by the removable converter bottom in TerniumBR. Regarding the result of the BOF refractory’s manual profile, a comparison was made with the laser measurement performed after deskulling the refractory coating post-campaing.It was observed that the average percentage of correct answers in the regions of the tuyeres was 51%, which caused its premature shutdown when it reached a measurement of 200mm. Regular calibrations of the laser measurement system were carried out to compensate for any distortion caused by the deformation of the shell, after correction, the equipment obtains a 91.2% accuracy..
