Formation mechanism of surface scale defects in hot ...
Thick oxide scale on steel may result in serious surface defects on hot-worked products. Yield efficiency and productivity of processes are considerably deteriorated by formation of defects. It is highly demanded to establish a way to produce hot-worked steels free from surface defects by controlling oxide scale.

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 ...
