S2: and determining control parameters of the electric control system according to the observed conditions in the S1, wherein the program of the electric control system sets the automatic cleaning time of each time to be 15-30min, the automatic cleaning frequency is that the automatic cleaning is performed again after the interval of 10-15min after the automatic cleaning is completed, the automatic cleaning graphite rope replacing device automatically replaces the cleaning graphite ropes once after the replacement frequency of the cleaning graphite ropes is 10-15min, the repetition frequency is preset, and the program of the electric control system is changed.
S3: the rope releasing motor and the rope collecting motor of the automatic graphite rope cleaning and replacing device are not started, so that the cleaning graphite rope is in a tensioning state after passing through the rope guide assembly, the distance between the left position sensor and the right position sensor in the automatic feeding device is adjusted to determine the automatic cleaning range, the feeding motor drives the lead screw guide rail to drive the wheel set mounting seat and the cleaning graphite rope in the automatic graphite rope cleaning and replacing device mounted on the wheel set mounting seat to automatically move left and right in the hearth, and the deposited carbon and the waste silk on the hearth wall are timely stripped and scattered.
S4: and starting the waste discharge system, adjusting the flow and pressure of gas in the gas inlet system and the gas exhaust system, quickly taking away deposited carbon and waste silk stripped and scattered in the automatic cleaning process, and keeping the waste discharge system in a working state before the furnace stops working.
S5: after the cleaning is completed, a program starts a rope releasing motor and a rope receiving motor of the automatic graphite rope replacing device, the speed matching of the rope releasing motor and the rope receiving motor is good, the rope releasing motor and the rope receiving motor respectively drive a rope releasing cylinder and a rope receiving cylinder to rotate, the graphite rope is cleaned after the rope releasing cylinder releases the rope, the graphite rope is automatically replaced on the rope releasing cylinder through a rope guiding assembly, the driving motor of the automatic feeding device stops rotating, and the automatic feeding device continues to work after the graphite rope is automatically replaced.
