Quality inspection is an indispensable part of modern industrial manufacturing. Steel as a major industry requires constant surveillance and supervision through its various stages of production. Continuous casting is a critical step in the steel manufacturing process in which molten steel is solidified into a semi-finished product called slab. Once the slab is released from the casting unit, th...

Presence of non-metallic inclusions & macro-flaws (cracks, pin holes/blow holes, segregation etc.), in a large number, in first and last continuously cast (CC) slabs of a sequence of casting, makes the CC slabs inferior in quality. Due to this problem these slabs were being downgraded and a huge loss in net realization was observed due to the difference in the prices of downgraded and prime gra...

The development of continuous casting to produce semi-finished products is now so far advanced that almost any grade of steel can be continuously cast, and in the most appropriate cross section for further shaping. High quality finished products can only be produced by using defect free slabs, blooms or billet. The removal of defects is either performed selectively by removing the specific defe...
