Roll designing is a very critical stage as it affects the cost of the rolls, life of the rolls, productivity of the mill, and the quality of the tube section. DeeTee uses COPRA ( German) software for the roll designing. The customer has to provide only the basic details of the mill and the input and output details.Salt bath heat-treatment is considered to be the best for tool steels. The high-carbon-high-chromium grades are through hardening steels i.e. , when heat-treated they attain the hardness right from the outer surface till the inner core. Proper heat-treatment gives good toughness, wear resistance and uniform hardness to the rolls used in rod mill, tube mill, wire rod mills.
