Method For Detecting And Classifying Surface Defects On Continuously Cast Slabs

A method for the detection and elimination of surface defects on continuously cast products, the method comprising:

• a.) detecting continuously cast defects and dimension of each of the detected continuously cast defects on a surface of a continuously cast product and evaluating a position and dimension of each of the detected continuously cast defects;
• b.) storing continuously cast defect information including the position and dimension for the each of the continuously cast defects;
• c.) processing the continuously cast product to create a finished product;
• d.) detecting finished product defects on the finished product;
• e.) storing the finished product defect information with respect to the exact position of the finished product defect on the finished product;
• f.) comparing the detected finished product defects with the detected continuously cast product defects to determine information that can lead to the finished product defects;
• and
• g.) based at least in part on the information determined by the comparing eliminating or preventing the finished product defects on subsequently produced finished products.
