Resumo
CRM is well equipped with a series of laboratory scale and on-site methods for evaluating the surface degradation behavior of work roll material in Hot Strip Mills. These methods are used for developing new work roll materials in direct relation with one of its long term industrial partner as well as for evaluating and solving unexpected degradation behavior on industrial site. These methods include classical mechanical testing (tensile and compression testing, hot hardness measurement) and specifically developed evaluation test and procedure at the level of the laboratory experimentation (three discs wear machine), of the continuous pilot mill trials (work roll with inserts) and on site (rollscope sensor, portable microscopy). This paper describes some examples of application of these techniques and the role they have played in a better understanding of the work roll surface degradation mechanisms and in the development, or optimization, of new roll grades.
