A study of the influence of the frequency of the inductor of induction furnaces on the structure and hardness of rolled cast iron was carried out. The research was carried out using SPHN and SSHHN cast iron. As a result of the conducted research, it is shown that when using induction furnaces with different frequency of the inductor, the properties and structure of their working layer differ. The hardness of cast rolls from higher frequency furnaces is found to be lower than from furnaces with a lower frequency of the inductor. Therefore, such conditions affecting the hardness of the rolls as chemical composition and cooling mode remain constant.
