The surface roughness of the cold rolling mill rolls is extremely high and needs to be controlled within ≤ 0.8 μ m to ensure the surface quality of the cold-rolled steel plate. Traditional grinding repair techniques result in a reduction of 0.5mm in roll diameter each time they are repaired. After multiple repairs, the rolls are scrapped due to their small size and have a short service life. The Daokedao laser cladding equipment adopts ultra-fine cladding technology, and the surface roughness of the coating after cladding can directly reach Ra1.2 μ m. After simple polishing, it can achieve a mirror effect of Ra0.4 μ m, and each repair only reduces the diameter of the rolling mill by 0.1mm, which is much lower than traditional grinding technology. After a large steel plant in South Korea applied this equipment to the repair of cold rolling mill rolls, the total service life of the rolls was extended from 5 repairs to 12 repairs, and the service life of a single roll was extended from 8 months to 24 months. Based on the 20 cold rolling production lines of the factory, the annual cost of purchasing rolling rolls is saved by 1.2 million yuan. At the same time, due to the improvement of rolling roll surface quality, the surface qualification rate of cold-rolled steel plates has increased from 98% to 99.8%, and the output proportion of high-end steel plates has increased by 5%, creating significant economic benefits.
