摘要: 复合轧辊是一种以高耐磨性及高强韧性材料分别作为工作外层及芯材的双金属复合材料。本文对国内外采用电渣冶金技术进行双金属复合以制备复合轧辊的堆焊复合法、液态金属表面复合法、自耗结晶器复合法等工艺方法进行了系统介绍,分析了自耗电极形式、导电回路方案、外层金属供给方式及设备结构等对双金属复合过程及复合轧辊综合性能的影响。同时,对不同工艺的基本特点及其控制关键技术进行了概括。对各电渣复合工艺技术发展历程及复合轧辊综合性能的稳定控制进行了分析,对电渣复合法制备双金属复合轧辊的未来发展前景进行了展望。

Abstract: The composite roll is a kind of bimetallic composite material which consists of a high wear-resistance mate¬rial as the working layer and a high strength, toughness material as the core respectively. In this paper, a systematical introduction is given for the preparation of bimetallic composite roll by electroslag metallurgy technology including ESR clad¬ding method, electroslag surfacing by liquid metal and consumable mold cladding method at home and abroad. The influence of consumable electrode form, conductive circuit scheme, supply method of the outer metal and equipment structure on the bimetallic cladding process and the comprehensive performance of composite roll are analyzed. At the same time, the basic process characteristics and control keys technology of the different methods are summarised. Based on the analyses of the development history of electroslag cladding technology and the stability control of composite roll performance, the future prospect and development of the preparation of bimetallic composite roll by electroslag cladding method is prospected.
