前言轧辊是轧钢生产中的关键备件之一,消耗量大,费用昂贵,供不应求。轧辊材质性能的好坏,直接影响到钢材的产量和质量。目前,各轧钢厂广泛采用埋弧自动堆焊法堆焊轧辊,是以特制的含有所要求的合金元素的焊丝配熔炼焊剂来达到掺合金的目的。然而,这种向堆焊层过渡合金元素的方法,尚有 Preface Rollers are one of the key spare parts in the production of rolled steel. They consume large quantities, are expensive and fall short of demand. Roll material quality is good or bad, directly affect the steel production and quality. Currently, the rolling mill widely used submerged arc welding method surfacing roller, is a special alloy containing the required alloying elements with smelting flux to achieve the purpose of blending gold. However, this method of transitioning alloying elements to the surfacing layer is still available
