查询词典 round-down

According to the basic equations derived under the two assumptions by Harold Lauffer—(1) the energy head of every point of a vertical section remains constant,(2) the flow lines are concentric circular arcs,this paper qives a comprehensive deduction of curvature effect in the characteristics of free overflow of round-crested spillway.118 runs of experiments of three round-crested spillway models of different size have been conducted by the author.

本文根据劳弗尔氏在两项假定[(1)垂直测线上各点所含能量为常数，(2)流线呈同心圆弧]下所导得的基本公式，作了详细的补充引伸，得出圆顶壩自由溢流时各项水力特性中的曲率影响计算公式。作者曾进行了大、中、小三个圆顶壩模型的试验共118组，试验成果基本上和导得的计算公式相合致。文中并根据试验资料制定了一些经验公式，应用时可更简便。

In order to roll round billets with accurate roughing shapes by a three-high roughing mill and stabilize production, a flexible pass design method was used to optimize the traditional conjugate pass through the distortion design of the bottom, side wall and pressure difference of the pass, realizing the application of the conjugate round pass on the three-roll mill.

为轧制料形尺寸准确的圆料、稳定生产，采用变通孔型设计方法对共轭孔型进行优化设计，通过对共轭孔型槽底、侧壁、压力差的变形设计，实现了共轭圆孔型在三辊粗轧机上的应用，轧槽咬钢顺利，成品圆料容易控制，完全满足后续工序的要求，同时减小了轧线的轧制事故，单套轧辊的轧制量可提高60%以上，取得了良好的经济效益。
