摘要
台车跑偏一直是烧结生产过程中经常发生的问题,严重时影响正常生产,降低设备使用寿命。本文通过分析台车运行过程中的受力情况,建立相关力学模型,研究由于左右侧台车摩擦力不均、台车驱动头轮、左右侧温度差等因素对台车运行轨迹的影响,分析得出台车运行跑偏的“平行四边形”和“梯形”状态,并指出烧结机在制造安装及运行过程中防止跑偏的注意事项。在此基础上,结合某钢厂360 m^(2)烧结机台车跑偏实际情况,通过不同的调整实践,检测运行参数,提出保证台车安装基准与减小两侧热膨胀的台车跑偏控制措施以及合理布置台车配重以平衡台车整体受力的跑偏调整措施,并将其应用于工程实际,空负荷和热负荷条件下烧结机上下台车全部回正,跑偏问题得到解决。
Trolley deviation has been a frequent problem during sintering production, which affects normal production and reduces equipment life in severe cases.By analyzing the force situation during the operation of the trolley, establishing the relevant mechanical model, and studying the influence of the uneven friction of the left and right side of the trolley, the driving head wheel of the trolley, and the temperature difference between the left and right side on the running trajectory of the trolley, the “parallelogram” and “trapezoidal” state of the trolley running deviation are analyzed, while the precautions for preventing deviation of the sintering machine in the manufacturing installation and operation process are pointed out.On this basis, combined with the actual situation of 360 m^(2) sintering machine trolley deviation in a steel mill, through different adjustment practices, the operating parameters are detected, and the trolley deflection control measures to ensure the installation benchmark of the trolley and reduce the thermal expansion on both sides, as well as the deviation adjustment measures for reasonably arranging the trolley counterweight to balance the overall force of the trolley are proposed for the actual engineering situation;and all the sintering machines under the condition of air load and heat load are been back to normal, so the problem of deviation is solved.
