Abstract
The article presents high-carbon hypereutectoid steel for production of hot rolling forged rolls. The steel contains 1.2 – 1.4 % of carbon, carbide forming alloying elements Cr, Mo, V and Nb improving wear resistance of the rolls, and Ni increasing hardening capacity. It has been found that steel of proposed composition provides ductility sufficient for hot deformation (forging) by moderate single compressions. Temperature range of ingot deformation has been detected: finite temperature deformation should not be below 900 °C, forging temperature – 1150 °C. According to its properties steel can be recommended for manufacturing solid-forged rolls and bandages for composite rolls of hot rolling from ingots of up to 10 tons weight.
