fluffing machine

On the basis of the geometric relationships between the preferentially growing direction of dendritic structure and the grinding faces,formulae are deduced to determine the crystal plane indexes of any three intersecting grinding faces of cast alloy samples.

根据枝晶优先生长方向与磨面之间的几何关系 ,导出了铸造合金试样任意三个相交磨面的晶面指数算式 ,并创建了两个含有不同算式的电子表格 ,分别可实现晶体位向及定向切割所需夹角的自动计算 ,使晶体位向的测算比常用的 X射线 Laue背射法简单、代价低、效率高。

? This essay introduces an example of Steel Fiber Reinforced Concrete construction and through the experiments we know more about mechanics targets as anti crack,anti pound,anti bend,anti break and the wear resistance of wear resisting surface.

本文介绍了钢纤维耐磨地面施工实例 ,并通过试验对钢纤维的抗裂性 ,抗冲击性 ,抗弯、抗折等力学指标 ,耐磨面层的耐磨性进行了进一步了解 ,从而论证了铣削钢纤维在工业与公用建筑地面施工中应用的优势以及钢纤维混凝土与耐磨面层相结合的施工工艺。
