FIELD: manufacture of rolling rolls, namely rolls from cemented carbide and cast iron for cold and hot rolling. SUBSTANCE: cast iron contains (mass%): silicium -(1.9-2.8); magnesium - (0.02-0.10); nickel - (0.5-4); manganese - (0.1-1); curium - less than 2, molybdenum - less than 1, ferrum - the balance. Cast iron includes 40% of perlite structure. EFFECT: possibility for creating necessary stress in roll having good metallurgical cohesion without heat treatment. 2 cl, 3 dwg
