Abstract

The invention provides a method for replacing sintering machine air box chutes and air box girders. The method includes the steps: manufacturing a hoisting tool; preassembling the air box girders; hanging the preassembled air box girders on the hoisting tool, and conveying the air box girders to the inside of an ignition furnace for mounting when the air box girders are mounted inside the ignition furnace; transporting the preassembled air box girders to a framework of a sintering machine by a crane for mounting when the air box girders are mounted outside the ignition furnace; mounting the air box chutes below the air box girders. The hoisting tool comprises two groups of supporting rods which are arranged on two trolleys respectively, the height of each supporting rod is lower than the scale height of the ignition furnace or a heat preserving furnace, a square frame is arranged at the top ends of two groups of supporting rods, and a lifting device is arranged on the square frame. The method can greatly shorten construction time and effectively solves the problem of difficulty in dismounting and mounting an air box and air box girders in the ignition furnace and the heat preserving furnace, labor intensity is reduced, and working efficiency and safety are improved.

Description

Technical field

[0001] The invention relates to the maintenance of a sintering machine;

[0002] In particular, it relates to a method for replacing the wind box chute and the wind box beam of a sintering machine. Background technique

[0003] The sintering machine uses a fan to draw air to make the sintered ore perform preliminary cooling. The ventilation channel between the sintering machine and the fan is composed of wind box, branch pipe, flue and other equipment.

[0004] After the wind box chute and wind box beam of the sintering machine reach the service life, they need to be replaced. When replacing the wind box chute and wind box girder, the wind box chute and wind box girder outside the area of โ€‹โ€‹the sintering machine ignition furnace and holding furnace are transported, disassembled, and disassembled with the cooperation of cranes and chain hoists. However, due to the wind box girder and wind flow process The total replacement workload is very large, the dismantling and ...
