轧辊的堆焊技术已有30多年历史,它逐步从对裂纹的修补和对磨损部位的再生发展到复合轧辊的生产。目前,用堆焊方法修复旧轧辊或生产表面层硬、心部韧性好的复合轧辊,已是延长轧辊寿命、降低辊耗、提高轧制生产率和产品质量的有力措施,在世界各国引起了普遍重视,并被广泛地采用。 Roller surfacing technology has more than 30 years of history, it gradually from the repair of cracks and the regeneration of wear parts development to the production of composite roll. Nowadays, it is a powerful measure to prolong roll life, reduce roll consumption, increase rolling productivity and improve product quality by repairing old rolls or producing composite rolls with hard surface and good core toughness by surfacing method. Emphasis, and is widely used.
