Abstract:
1. 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, wherein a relationship between the finished product defects on the finished product and the continuously cast defects on the continuously cast product and a probability of occurrence of surface defects are used for a defect prediction, wherein the method is a learning process and based on the defect prediction, only continuously cast defects that would result in finished product defects are eliminated on the subsequently produced continuously cast products.
