钢轧辊的堆焊技术已有20多年的历史,它逐步从对裂纹的修补和对磨损部分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效措施。现就我公司从美国引进和生产的几种轧辊堆焊用管状焊丝的性能、堆焊工艺及应用实例介绍如下。 Steel roll surfacing technology has been more than 20 years of history, it gradually from the crack repair and wear parts of the development of the development of composite roll production. At present, the use of surfacing method to repair the old roll or the production of hard surface hardness, heart toughness of the composite roll has been extended roll life, reduce roll consumption and improve rolling productivity and product quality effective measures. Now my company introduced from the United States and the production of several roll surfacing with the performance of tubular welding wire, welding technology and application examples are as follows.
