一种应用最广的铁矿石烧结方法。带式烧结机是钢铁工业的主要烧结设备，它的产量占世界烧结矿的”%。现代带式烧结机的烧结室的断面示于图1。烧结机是由铺设在钢结构上的封闭轨道和在轨道上连续运动的一系列烧结台车组成。首先将从烧结矿中分出的铺底料(10~Zomm)加在台车上，以保护台车算条和减少废气含灰量。然后再将烧结混合料经布料机加到台车上，并保持规定的高度。随之进行抽风点火烧结，随台车前进，烧结过程由料层表面不断向下进行。至机尾，烧结完成，台车翻转将烧结饼倾卸。空台车沿下部轨道运行至烧结机头部，再加料进行点火烧结，如此循环不断。烧结饼经破碎和筛出热返矿后，送冷却机冷却。从料层中抽出的废气经台车下的风箱至集气总管和除尘装置，由抽风机排向烟囱。dalshi shaojieji shaojie带式烧结机烧结(sintering by sinter strand)}馨爵鬓 森币乒、，一，，，，.、一，r，_， 图1现代抽风带式烧结机烧结室断面图 带式烧结机由烧结台车、密封装置、钢结构框架和3.om、3.sm、4.om及5.om几种。由于台车处于高温传动装置组成。台车是放置烧结料和进行抽风烧结的下工作，因之不仅要求材质能耐高温、而且要求结构合重要部件。它是由铸钢车体、侧板、算条和滚轮组成(见理减少高温变形的影响。在台车和风箱滑道之间有密图2)。按烧结机大小、台车宽度有1.sm、2.om、2.sm、封装置(水管式密封或弹簧式密封)，对减少漏风和节 省电耗有很重要的作用。在机头和机尾的风箱隔板与 ‘卜~一一-一-2500—--，司 创盯一一一下台车之间用重锤连杆式密封。为保证台车在受热膨胀 .对胭奎至斋荞至幕筹拜三三三三三尸气润后仍能平稳运转，在机尾卸矿端设置专门的摆动机架 书阳~一一一即一一邵一二一一一.一-期d{丹一去或可水平移动的尾部星轮。烧结台车借助于机头部分 !毛一一一一，。。州泞的传动装置向前运动，传动装置是由电动机、减速机和 卜卜一一一一-—3216—一一一一月’传动大齿轮所组成。(见彩图插页第2、3页) (杨兆祥蔡法率)纂戳磷~ 图2烧结台车
