Hot rolling mill work roll
1, Nodular cast iron rolls
Ductile iron with more Ni, Mo alloy can obtain good pearlite, bainite, martensite matrix organization, and graphite shape for the ball, good thermal conductivity, tensile strength, high by changing the organization as the bainite, martensite and needle ductile iron the chemical and heat treatment process, we can obtain very dense mesh primary cementite, improve abrasion resistance.
-- Mechanical Property
Rod surface hardness
HSD70-90
Core department hardness
HSD35-55
Core department tensile strength
>500Mpa
-- Application
Nodular cast iron rolls are mainly used in the billet and roughing stand of hot rolling mills; Sections mills, tube mills, bar mills and wire mills.
2)Indefinite Chilled cast iron roll
The feature of this casting roll is that it shaped into graphite ball and its performances can be compared with that of alloy infinite chilled roll, and its intensity is higher than that of infinite chilled one, so it is usually used for rest energy casting.
