1results about How to "Consistent hardness" patented technology

This utility model provides a stainless steel cold-rolled annealing assembly, belonging to the technical field of stainless steel cold-rolled annealing. It includes two cooling rollers, each with multiple heat dissipation grooves, a spiral guide rib installed on the inner wall of each roller, two symmetrical baffles installed on each spiral guide rib, and threaded rods installed at both ends of the inner wall of each roller. This structure, by creating heat dissipation grooves, significantly increases the contact area between the roller and the air compared to traditional smooth rollers or simple grooves. This allows for more efficient transfer of heat absorbed by the roller to the air, accelerating heat dissipation, improving overall cooling efficiency, avoiding uneven cooling of the coil caused by localized overheating of the roller, and ensuring consistent hardness across all areas of the coil. Simultaneously, a ceramic wear-resistant coating is sprayed onto the non-contact side of the spiral heat dissipation grooves. This coating has high hardness and strong wear resistance, effectively resisting the erosion and friction of impurities in the cooling environment against the groove walls.
