摘    要：为提高铬系冷轧辊钢的使用性能,在MC3及MC5材质的基础上分别研究了铬和硅元素对冷轧辊钢耐磨性和淬透性的影响。结果表明,随着铬含量的增加,冷轧辊钢的磨损失重量逐渐减少并趋于平稳,耐磨性得到提高;Cr含量为5%时,随着硅含量的增加,冷轧辊钢的淬透性得到提高,硅含量在1.5%左右时,冷轧辊钢具有良好的耐磨性。

Abstract: In order to improve the property of Cr-series steel for cold roll blank,the influence of Cr and Si elements on wear resistance and hardenability were studied in MC3 and MC5 steels.The results showed that the abrasion loss of cold roller steel decreased then tended to smooth with the increasing of Cr content and the hardenability was improved with the increasing of Si content,while the cold roller steel exhibited the best wear resistance when the Si content was about 1.5% on the premise that the Cr content was 5%.
