摘要
在轧辊用高镍铬白口铸铁中．添加不同量的稀土金属．测定和研究了稀土对其机械性能的影响．结果表明：稀土元素可以提高这种高合金铸铁轧辊的强、韧性和热疲劳性能。
The machanical properties of high Ni-Cr cast iron for roller beeme4sured with different RE addition. the experemental. The experemental resultsshow' that the strength-tougmess and thermal fati-gue of the material areenlproved considerally by RE.
