三辊联合穿轧机的研制与应用

DEVELOPMENT AND APPLICATION OF THREE ROLL PIERCING AND ROLLING COMBINED TUBE MILL

介绍了三辊联合穿轧(SCZ)法的开发背景、基本原理、工艺与设备特点和使用情况。SCZ法是指在一台三辊斜轧机上,用一个道次便获得内外表面质量及尺寸精度均合格的生产无缝钢管的方法。该工艺与设备己通过部级鉴定,目前正在推广应用。

Background, basic principle, technology equipment characteristics and industrial application of SCZ are described in the paper. SCZ is a method by that seamless pipes qualified both in inner and outer surface and size precision are manufactured through a single pass on the three roll cross mill.
