Notes:
The consumption of work rolls in cold strip mills is significant. One of the key issues forwork rolls is the surface roughness which affects the rolling stability and surface finish of the strip.The produced strip has lower surface finish if the roll surface roughness is large. However, if theroll surface roughness is small, it is not helpful for establishing the rolling process, which willreduce the productivity. In this case, a laser treatment is employed to increase the value of rollsurface roughness. In order to reduce the times of roll grinding, the cold strip mill and rollmanufacturers have developed new types of rolls such as the rolls containing Ti to increase the rollwear resistance in cold strip rolling. Results show that the new 4CrTi roll has a significantadvantage of preventing decrease of the roll surface roughness. The size and generation of particlesduring roll wear process and the effect of Ti on roll wear have been discussed
