Abstract

Study of the nature of low-carbon structural steel rolled product surface defects by a metallographic method makes it possible to establish that formation of flaws in rolled product in the bottom part of ingots is connected with the presence of gas bubbles and extraneous inclusions. The effect of aluminum on rolled product surface quality is analyzed. The optimum aluminum content in steels 09G2S – 0.011–0.015%, S355j2G3 – 0.021–0.025% is established, and this makes it possible to improve metal ductility, reduce the degree of ingot defect development, and reduce rolled product rejection for surface defects.
