A method of melting and casting of a steel that improves its cleanliness and homogeneity is a main requirement to manufacture proper initial material for a wire rod production. The ability of a wire rod to be drawn is related to the types of non-metallic inclusions and their geometrical parameters. The tensile strength, contraction of initial wire rods as well as a schedule of passes and lubricant conditions were similar for all considered heats which differed only be methods of Deoxidation. The wire rod originated from the heat deoxidized by CaSi with diminished amount of FeSi and Al. (Heat A) exhibited the highest ability for drawing, allowing for total reduction of 93.7 percent. Among analyzed properties, a statistically significant correlation with nonmetallic inclusions parameters and wire rod drawability was found by an impact strength test. The impact strength and stress intensity factor K_(IC) is very sensitive to a variation of some parameters of non-metallic inclusions most notable the sum of inclusions length on 1 mm~2 and their average distance. Mechanical properties as R_m., Z, A_(100) are not sufficient criteria for determination of wire rod drawability. To some extent, as a drawability meters can be considered: the number f twists and bends L_s, L_Z a degree of upsetting to occurring visible cracks and fatigue resistance in rotational beam test.
