The invention discloses an air box and air box end seal installation method of a sintering machine production line. The method is characterized by comprising the following steps: a, after an air box side beam is installed in place, checking the elevation, levelness and center deviation of the side beam; b, before slideways are installed, carefully measuring the machining size of each slideway and recording the machining sizes; c, coating contact surfaces of the slideways and the side beam with high-temperature-resistant sealants; d, when an air box floating beam is installed, adjusting the gap between the floating beam and a framework cross beam to 0.1-0.5 mm by adjusting a gasket group; e, before an air box is installed, cleaning up oil stains and rust on flange faces; and f, carefully checking the machining quality with all parties before installing air box end seals, and especially checking square wear-resistant lining plates on the surfaces of the end seals. The air box and air box end seal installation method of the sintering machine production line has the advantages that comprehensive planning is achieved, an overall arrangement is achieved, the operability is high, the mounting precision of the air box and the air box end seals of the sintering machine production line is high, the steps are connected and coordinated smoothly, the installation efficiency is improved, and the engineering cost is reduced.
