roll fracture often takes place in hot rolling section steel. the fracture position is mainly located at the roll caliber, roll neck and boundary between the roll neck and roll body.
热轧型钢过程中经常发生轧辊断裂现象,断裂部位主要在轧辊的孔型处、辊颈处及辊颈与辊身交界处。
in order to improve bearing capacity and compactness of the roll system, a method of double circular arc conical surface transition curve for roll neck is put forward.
为了提高轧辊的承载能力和辊系结构的紧凑性,提出了对辊颈双圆弧锥面过渡曲线的优化设计方法。
however, the regularly banded roughing and wearing occurring on the roll neck surface seriously effect the work age of the machine. this paper develops the finite element method to ana…
然而,锥套与辊颈装配过程中部分带状区域的规律性拉毛磨损对其粘结和使用寿命造成严重影响。
the method of the invention is applicable to the smelting of the wide and heavy plate working roll neck and can be used for repairing other nodular iron castings.
本发明方法不仅适用于宽厚板工作辊辊颈熔补,而且还能用于其他球墨铸铁件的修补。
this paper presented the mechanism of fretting fatigue failure that happened on the contact surfaces between sleeve and roll neck of oil-film bearing under the rolling load.
