Product Induction
Alloy cast steel roll is made of high-quality molten steel and advanced casting and heat treatment technology. It has high strength, excellent thermal crack resistance, toughness and wear resistance. It is suitable for rough and medium rolling mills for section steel, rolls for rough rolling mills for hot-rolled strip steel and hot-rolled strip steel support rolls. The metallographic structure of the roll body is pearlite or tempered troostite.
