Through metallographic structure analysis,wearing tests and production practice,the result shows that abrasion resistance of guide roll reaches the best and service life is prolonged as 2.4 times as no-sulphur guide roll when sulphur content 1.5%.

• 从对试验钢的金相结构分析和磨损试验；以及经生产实践；结果表明当硫含量在1.；5%25时的导辊耐磨性最佳；使用寿命达到了不含硫导辊的2
