Title:
【発明の名称】耐摩耗耐焼付性熱間圧延用ロール
Document Type and Number:
Japanese Patent JP3205745
Kind Code:
B2
Abstract:
A hot-rolling roll excellent in wear and seizure resistances, which has a composition by weight consisting of 2.0 - 4.0 % of carbon, 0.5 - 4.0 % of silicon, 0.1 - 1.5 % of manganese, 1.0 - 7.0 % chromium, 2.0 - 10 % of molybdenum, 2.0 - 8.0 % of vanadium and the balance consisting of iron and inevitable impurities, a matrix structure consisting essentially of martensite, bainite or pearlite, and a metallographic structure comprising, by areal proportion, 0.5 - 5 % of graphite particles, 0.2 - 10 % of MC-based carbide and at most 40 % of cementite. The roll is well suited for a work roll in the latter stage of the finishing line of a hot strip mill.
