The brand selection of roll ring is also related to the rolling mill equipment condition, rolling speed, rolling technology and cooling condition.Generally speaking, if the equipment condition is good, the rolling process is stable, the rolling speed is slow and the cooling effect is good, then under the same conditions, the stress and thermal impact on the roll ring is small. Therefore, high hardness and good wear resistance can be adopted as far as possible under the premise of meeting the strength and toughness to maximize the service life of the roll ring.On the contrary, under the premise of meeting the hardness, the brand with high strength and good toughness should be selected as far as possible in order to ensure and avoid not breaking roller.
