Abstract

Possibility of applying new roll materials (FRM (Fiber Reinforced Metal) roll materials), which are consisted of high speed tool steel reinforced with alumina fiber, to work rolls for hot rolling process is investigated by several laboratory tests. The FRM roll material expected to have superior tribological and mechanical properties, have been manufactured using sintering method (Hot Isostatic Pressing process) with which ceramic content can be increased. Wear resistance and mechanical properties and hot rolling characteristics of the FRM roll materials were investigated. As the results, it was clarified that the FRM roll material had three times or more wear resistance, a little lower rolling force and friction coefficient, and good thermal crack resistance and higher tensile strength in comparison with conventional casting roll materials such as a high speed steel roll material. Therefore, FRM roll materials can expectantly be used for hot rolling mill as high performance roll materials instead of high speed steel roll material.
