Abstract
The invention discloses a method for rapidly replacing trolleys in a sintering machine online. The method comprises the steps as follows: step one, determining that the number of the to-be-replaced trolleys is 1 to 3, and controlling a mixture in a mixture bin within 10%-20% of a bin space; step two, intermittently starting and stopping a discharge device until the thickness of cloth in the to-be-replaced trolleys is in a range of 180-210mm; step three, when the to-be-replaced trolleys move to be right above a fourth bellow from the tail of the sintering machine, adjusting the opening of an air door of a main exhaust fan to be in a range of 15%-20%; step four, enabling the to-be-replaced trolleys to break away from a running track of the sintering machine through manual operation, and placing standby trolleys in positions of the to-be-replaced trolleys; and step five, adjusting the temperature in a hearth of an ignition device to be at 1100-1250 DEG C, and recovering the normal production of the sintering machine when both temperatures in the second and third bellows from the tail of the sintering machine reach above 280 DEG C. According to the method, the rapid and online replacement of the trolleys in the sintering machine is realized, and the production efficiency is improved.
