A simulation of roll wear in hot rolling processes ...

Hot rolling is an important steel production process. Rolls in a hot rolling mill cost significantly and influence quality of products. Wear is a major factor of roll fault. So, it is very important to study roll wear at high temperature, although roll wear study in a real rolling mill is very difficult, especially for a hot rolling mill. To meet the need of practical production for the ...
