复合辊
组合式轧辊
Examples
- It is pivotal to improve the formation and distribution of carbides in the solidification microstructure of composite rolls of high speed steel
采取必要的措施，预先改善铸态高速钢中原始碳化物的大小和分布在复合轧辊用高速钢中是很为关键的。 - On the base of the research of composition , the influence of modification with re , ti , mg , re - ti - mg ( wt , % ) on high speed steel of composite roll is investigated emphatically
在对化学成分研究的基础上，重点研究了利用re 、 ti 、 mg 、 re - ti - mg -进行变质处理对复合轧辊用高速钢显微组织的影响。 - The high speed steel of composite roll is characteristic of high carbon and high alloy elements . so it is easy to form a lot of netlike carbides . these carbides which are very hard and fragile and are very difficult to be eliminated by heat treatment can depress the properties of high speed steel
复合轧辊用高速钢具有高碳和高合金的特征，容易形成大量网状碳化物，这些网状碳化物又硬又脆，会严重降低高速钢的性能，且难以用热处理的方法予以消除。 - The composite roll of high speed steel has the synthetical life of over ten times more than traditional high cr cast iron roll . now the research and production of the high speed steel for roll are very drastic . in this thesis , the microstructure , heat treatment and performance of high speed steel fe - 2 % c - 4 % v - 4 % mo - 5 % cr - x % w ( wt ) are studied systematically by using metallograph , method of lattice , xrd , sem , eds and hardness
本文利用金相法(包括黑白金相和彩色金相) 、 x射线衍射( xrd ) 、扫描电子显微镜( sem ) 、能谱( eds )及洛氏硬度分析仪等手段，对复合轧辊用高速钢fe - 2 c - 4 v - 4 mo - 5 cr - x w (其它部分如未作特殊注明均为质量分数)合金系的显微组织、热处理工艺及性能进行了系统地分析。 - During the recent years the breakthrough of manufacturing the new type of composite roll has been made . it is possible for the composite roll of high cr cast iron widely used at present to be replaced by the composite roll of high speed steel ( hss ) in the ten years
近年来，将高速钢用于制造新一代复合轧辊方面取得了突破性进展，高速钢复合轧辊的综合使用寿命可以比传统用高铬铸铁轧辊提高数倍以上，目前被广泛采用的高铬铸铁复合轧辊，有可能在十年之内被高速钢复合轧辊取代。
