一、前言旋风筒及管道在当今工业炉窑中经常出现,如在水泥窑、石灰窑和镁砂焙烧炉中应用较广泛。特别是旋风筒内衬施工非常困难,其原因是旋风筒的形状是锥形体,应用的砖型太多。因此,设计单位往往不易设计出复杂异型的定型砖,这样就给施工带来不可避免的大量改形和砖加工。所以,砖加工尺寸的计算将成为砌筑旋风筒内衬的关键工序。二、砖加工的设计 1.旋风筒任一直径的计算在旋风筒施工图纸中,一般给定2个直径尺寸,一个是顶部直径φ_(max)、一个是底部直径φ_(min),中间的任一直径尺寸一般都不给出。由于施工单位在设计砖加工时必须应用到旋 First, the preface Cyclones and pipes often appear in today’s industrial furnaces, such as cement kilns, lime kilns and magnesia roaster used more widely. In particular, the cyclone liner construction is very difficult, because the shape of the cyclone is a cone body, the application of brick too much. Therefore, the design unit is often not easy to design complex shaped shaped brick, thus giving the construction of a large number of inevitable transformation and brick processing. Therefore, the calculation of brick processing size will be the key process masonry cyclone lining. Second, the design of brick 1. Cyclone any diameter calculation Cyclone construction drawings, usually given two diameter dimensions, one is the top diameter φ_ (max), one is the diameter of the bottom φ_ (min), the middle Generally not given any diameter size. As the construction unit in the design of brick processing must be applied to spin
