Способ относится к ремонту сваркой и может быть использован при ремонте бандижированных роликов зоны вторичного охлаждения машин непрерывного литья заготовок, а также других бандажированных деталей металлургического и прокатного оборудования. Для повышения срока службы бандажированных роликов по мере износа бандажа проводят ремонт, включающий удаление дефектов, предварительный и сопутствующий подогрев, наплавку колец материалом мартенситного класса с последующей термической и механической обработкой, причем наплавку производят материалом с эквивалентным содержанием углерода (Сэ, %) 0,4-2,0 при соблюдении соотношения между Сэ и толщиной наплавленного слоя Сэ/б = 0,08 - 2,2.The method relates to the repair by welding and can be used in the repair of the bandaged rollers of the secondary cooling zone of continuous casting machines for billets, as well as other banded parts of metallurgical and rolling equipment. To increase the service life of the bandaged rollers as the bandage is worn out, repairs are carried out, including removing defects, preliminary and concurrent heating, surfacing the rings with a material of the martensitic class with subsequent thermal and mechanical treatment, and welding is produced with a material with an equivalent carbon content (C e %) 4-2.0, while respecting the relationship between C e and the thickness of the deposited layer With e / b = 0.08 - 2.2.
