Practice of Upgrading Rectangle Expansion Joints for High-temperature Dry Quenching Cokery

In consideration of the problem that the rectangle expansion joints for the high temperature dry quenching cokery are liable to fail, the causes leading to the failure of expansion joints are analyzed based on actual operations and then the high temperature rectangle expansion joints are upgraded suitably and efficiently. Therefore any abnormal phenomena didn＇t occur dur- ing the operation of the eokery for over one year. And what＇s more it is convenient for carrying out the equipment maintenance or equipment overhaul and the service life of expansion joints are pro- longed while the cost for operating the cokery is decreased.
