Study and Minimization of Surface Defects on Bars and Wire Rod Originated in Continuous Cast Billets

Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 2

Abstract

 Abstract: In order to minimize surface defects in long products, their origin needs to be assessed .To this purpose a methodology was developed, that includes metallographic studies on bars and wire rod using several reagents. A description is made of the different steps involved in this method, including the use of etchants to determine the former position of the defect in the billet, it is also discussed the interpretation given to internal oxidation, scale inside the defect, decarburization, and other metallographic features. A discussion of pin holes and transverse cracks on billet is made, taking into accounts its aspect and metallographic features on billet, the evolution during reheating and rolling and the final aspect and metallographic features on bar/wire rod. Root causes of these defects and solutions recommended are analyzed for eachcase.
