一、前言带式焙烧机(或带式烧结机)是球团(或烧结)工业的主体设备。目前,国内外所用的带式焙烧机与带式烧结机采用头尾轮节圆直径相等、带有尾部摆架结构型式的较多。这种结构型式具有以下优点:能自动调节台车热膨胀的间隙;其特殊曲线的弯道避免了台车的撞击与台车体的边角磨损;由于采用了弹簧弹压式密封装置,因而能减少漏风率等等。 I. Introduction Belt roasting machine (or belt sintering machine) is a pellet (or sintered) industry’s main equipment. At present, the band roaster and belt sintering machine used at home and abroad adopt the head-to-tail wheel pitch diameter equal, with the structure of tail swing frame more. This type of structure has the following advantages: automatic adjustment of the thermal expansion of the trolley gap; the curve of its special curve to avoid the trolley impact and trolley body corner wear; due to the use of spring-loaded sealing device, which can reduce Leakage rate and so on.
