钢轧辊孔型堆焊,是冶金企业提高轧辊寿命和降低轧辊消耗的有效方法。近年来苏联已广泛加以采用,并且取得了很大的成绩。目前,如苏联亚速钢厂、马格尼托哥尔斯克冶金工厂等已经在使用管状合金粉末焊条和带有合金成份的陶制熔剂来堆焊初轧辊。这样便提高了堆焊金属中合金元素的含量,从而提高了轧辊的表面硬度和耐磨性,使轧辊的使用寿命大大延长。鞍山钢铁公司第一轧辊车间,在1955年以前, Steel roller hole surfacing, metallurgical enterprises to improve the life of the roll and reduce the roll consumption of effective methods. In recent years, the Soviet Union has adopted it extensively and has achieved great success. At present, such as the Soviet Union speed steel mill, Magnitogorsk metallurgical plant, etc. are already using tubular alloy powder electrode and the alloy composition of the ceramic flux to build up the first roll. This increases the alloying element content of the surfacing metal, thereby increasing the surface hardness and wear resistance of the roll, greatly extending the service life of the roll.
