摘　　要：为了提高轧辊的修复质量和降低工艺成本,采用爆炸焊接技术对磨损失效的轧辊进行修复,在轧辊基体上爆炸复合耐磨性和强度较好的金属管,对轧辊进行修复。本文中,基于爆炸焊接理论分析、数值计算和实验开展轧辊修复的研究,并在连轧生产线上实际运行检验。与堆焊技术修复的轧辊相比,采用爆炸焊接技术修复的轧辊耐磨性和抗腐蚀性都比较高。Explosive welding technology was used for the repair of roller failed by wearing to improve the quality and cut cost.The roller was repaired by blast cladding high strength metal pipe with good wear-resistance.Research for roller repairing was carried out based on the theoretical analysis of explosive welding,numerical calculation and experiments.The repaired roller was successfully tested on a continuous casting production line.Compared with that repaired by hard-facing,the roller repaired by explosive welding has higher wearing and corrosion resistance.
