The support rollers need to meet the following performance requirements during operation: Stiffness: During the rolling process, the support rollers support the working rollers to ensure that the working rollers have high stiffness and small deformation during operation. Contact fatigue strength: During use, the support rollers are always in rolling contact with the working rollers or the intermediate rollers, which is very easy to produce work hardening. The support rollers are required to have high contact fatigue strength, reasonable stress state and crack propagation resistance. Wear resistance: The middle part of the support roller will form a concave shape due to wear, and the contact stress at both ends of the roller body will increase sharply, resulting in peeling. Therefore, the rollers are required to have excellent wear resistance to delay and reduce the formation of concave roller shapes. Roll neck strength: The support rollers have a long service life, and the roll necks are subjected to alternating bending stress for a long time. In order to prevent the roll necks from breaking, the roll necks are required to have good yield strength, toughness and fracture resistance. #steelmill #rollingmill #millrolls #steelindustry #steelwork #steeltechnology #steelplant #LMMGROUP
