“…Dinesh proposed a method to check the surface defect, root causes of the defect; and solutions were recommended for each case [17]. Since secondary cooling control is an important factor in the continuous steel casting process, simulation and modeling of this issue have been published in the literatures [18][19][20][21][22][23]. A mathematical model of the heat transfers and solidification was developed for a continuous casting of round billet and calibrated with superficial temperature measurements in the industrial plant, then the water flux density distribution of flat jet and full cone jet nozzles along the secondary cooling zone was determined experimentally [10].…”

In continuous casting process, defects of the steel billet (e.g. crack, pinhole, blowhole, central shrinkage, slag entrapment and appearance deviation, etc.) negatively affect the quality and the yield of rolled products. This research has been carried out to investigate some defects which often occurred in Vietnamese steel plants. The experimental work was conducted in an industrial 4-strands continuous casting machine with the billetâ€™s cross-section of 130Ã—130 mm2. The position, generating cause identification of these defects and proper measures have been discussed. A change in the steel compositions and the water distribution during secondary cooling was applied to improve the steel billet quality It has shown that the billet defects have greatly decreased and the quality of billet has obviously increased.
