Maintenance method for ignition furnace of sintering machine and new ignition furnace

The invention relates to the technical field of ignition furnace maintenance, and particularly discloses a maintenance method of a sintering machine ignition furnace and a new ignition furnace, and the maintenance method of the sintering machine ignition furnace comprises the following steps: firstly manufacturing an outer layer frame of the new ignition furnace, and hoisting the outer layer frame above a trolley; a partition piece is installed in a hearth of the new ignition furnace; manufacturing a fireproof layer of a new ignition furnace; the sintering machine is shut down for maintenance, and the trolley stops running; dismantling the old ignition furnace, and meanwhile dismantling the partition piece; and the new ignition furnace is moved to the position of the old ignition furnace, and pipeline connection is completed. According to the method, manufacturing and baking of the new ignition furnace are completed during production of the sintering machine, the hearth and the trolley are separated due to th
