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 m² 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 have been back to normal, so the problem of deviation is solved.
