前言随着轧制条件的苛刻化,要求热轧薄板用工作辊具有高的耐磨性和抗桔皮状缺陷性能。为了制造满足这些要求的轧辊,掌握作为轧辊材料基本特性的高温磨损特性是很重要的。作为热轧辊材料,一般使用阿达迈特镍铬耐磨铸铁 Preface With the harsh rolling conditions, the work roll for hot-rolled sheet is required to have high wear resistance and resistance to orange-peel defects. In order to produce rolls satisfying these requirements, it is important to know the high-temperature wear characteristics as the basic characteristics of the roll material. As hot roll material, Adamant nickel-chromium wear-resistant cast iron is generally used
