马氏体-贝氏体合金球铁焊管机轧辊

Study of Martensitic Bainitic Alloyed Ductile Iron Roller for High Freguency Welding Pipe Mill

试验研究了用马氏体贝氏体合金球铁代替 Ｇ Ｃｒ１５ 钢制作高频焊管机轧辊，介绍了该材质的工艺技术要点。结果表明：合金球铁轧辊较 Ｇ Ｃｒ１５ 钢轧辊寿命提高５０％ 以上，生产成本下降２０％ ～３０％ ，具有一定的经济效益。

In this paper,use martensitic bainitic (M B) alloyed ductile iron as substiture for steel GCr15 in manufacture of high frequency welding pipe mill roller has been studied and techology characteristics of this material have been introduced.The results show that the service life of M B ductile iron roller has increased more than 50% as compared with that of steel GCr15 roller,the production cost has reduced by 20%～30%.So this material roller has wide economic value.
