Alloy infinite chilled cast iron roll
Dongye Roll has one of the best Alloy infinite chilled cast iron rolling mill brands in China, and is one of the competitive roll manufacturers and suppliers in the country. Welcome to visit our website.
Alloy infinite chilled cast iron rolling mill is a type of cast iron with fine intergranular graphite evenly distributed in the working layer of the rolling mill barrel. The size, shape, and distribution of graphite and carbon compounds are controlled by the quenching effect and the content of alloying elements. The addition of alloying elements such as Manganese, Nickel, Chromium, and Molybdenum changes the matrix structure from pearlite, bainite to martensite. The presence of a small amount of fine graphite improves the anti peeling, heat resistance, and wear resistance of the rolling mill. The hardness gradient of this roll in the working layer of the roll body is relatively small, making it suitable for the intermediate and finishing rolling stands of bar, wire, and profile mills.
