Application of the waste heat recovery system and energy-saving in the strip continuous annealing fu

The common problem of cold strip continuous annealing furnaces is high exhaust gas temperature and great energy consumption.Taking the cold-strip continuous annealing furnaces of Baosteel No.4 cold mill plant as an example,several waste heat recovery systems in the annealing furnaces are compared and their advantages and disadvantages are analyzed through different energy-saving technologies.
