    • Disclosed herein is a gas dispersing device to be employed in a fluidized bed preliminary reducing furnace. The gas dispersing device is constructed of a plurality of rotatable round bars arranged in multiple stages so as to form a grate. The gas dispersing device includes a rotating mechanism for rotating each bar.According to the present invention, deformation of the bars due to a temperature change thereof can be avoided to thereby extend a life of the dispersing device. Furthermore, blinding of the dispersing device can be prevented to thereby effectuate a stable operation of a fluidized bed. Accordingly, productivity in the fluidized bed reducing furnace is improved, and labor saving is realized.

    • A toothed belt having an endless rubber band formed with projecting tooth portions, the rubber band having tension members buried in parallel therein. A cloth cover is fastened to the toothed surface of the band. The cloth is formed of woven fibers, and one of the warp and woof fibers of the cloth has a high-adhesive characteristic, and has a greater exposed surface area on one side of the cloth, which side is fastened to the toothed surface. The other of the warp and woof is formed of a fiber having properties suited for the working environment, such as properties of abrasion resistance and low friction, these latter fibers having a greater exposed area on the other side of the cloth, which other side is positioned for engagement with a toothed pulley.
    • 具有形成有突出齿部的环形橡胶带的齿形带,所述橡胶带具有平行地埋设在其中的张力构件。 布罩固定在带子的齿形表面上。 布由编织纤维形成,布的经纱和纬纱之一具有高粘合特性,并且在布的一侧具有更大的暴露表面积,该侧被紧固到齿形表面。 经纱和纬纱中的另一个由具有适合于工作环境的性能的纤维形成,例如耐磨性和低摩擦性,这些纤维在布的另一侧具有较大的暴露面积,另一侧是 定位成与齿形滑轮接合。
