一种行星轧机用轧辊
摘要：
一种行星轧机用轧辊，包括轧辊中心定位孔、锥体形工作面，该锥体上工作线有锥体大端斜直线、小端斜直线、小端圆弧面、大端斜直线与小端斜直线之间的波浪纹和突变区过渡圆角，其特征在于：该突变区过渡圆角曲率半径为R5～R15毫米。本发明应用在铸轧法铜管生产线中行星轧机用的轧辊，设计突变区过渡圆角为R5～15mm，解决了生产过程中，轧辊开裂的重大技术问题。通过设计合理的大端机构，增加一道波浪纹，解决了轧辊使用时喂进困难和速度低的问题。
摘要（英）：

The roll for planetary rolling mill has central locating hole and conic working surface, and the conic working line includes large end inclined line, small end inclined line, small end curved line, and wavy line and abrupt change area transition round angle between the large end inclined line and the small end inclined line. The present invention features that the transition round angle in the abrupt change area has curvature radius of 5-15 mm. The transition round angle in the abrupt change area of curvature radius in 5-15 mm makes the roll improved greatly, and the reasonable large end mechanism and increased wavy line makes feeding easy and raises the rolling speed.
