烧结机台车起拱原因分析及处理

韶钢5~# 360 m~2带式烧结机回程台车起拱现象严重。通过在烧结生产过程中,测量回程台车的不同起拱高度,观察其运行趋势,同时在停机时测量尾部弯轨面与齿板面的关键点数据,从力学上分析引起台车起拱的原因,提出更换尾部星轮齿板、调整弯道与齿板间隙、同步调整水平轨道"压轨"等解决方案。实践结果表明:处理措施实施后,台车起拱高度由均值35 mm下降至5 mm以下,因起拱造成的高电流运行均值下降至40 A,有效稳定了设备和生产。     

带式烧结机台车栏板开裂原因分析及改进

带式烧结机台车栏板是烧结机运行过程中的主要易损件之一,为了克服当前带式烧结机台车栏板受热产生裂纹、寿命低、更换成本高等问题。本文主要从台车栏板的材质、铸造生产、现场运行工艺等方面进行分析,从而提高台车栏板使用寿命、烧结生产作业率和烧结矿质量,减少带式烧结机的检修时间和漏风率,进而降低了钢厂运行成本。
