The utility model provides a high-temperature flue gas heating and heat exchange conversion tube. The high-temperature flue gas heating and heat exchange conversion tube comprises an outer sleeve, a U-shaped conversion tube and heat transfer fins. The two ends of the outer sleeve allowing high-temperature flue gas flow to circulate are open, the structure is simple, the manufacturing cost is saved, at least part of the bent pipe section can be exposed out of the lower end opening of the outer sleeve, the bent pipe section can be arranged at the high-temperature flue gas furnace in an exposed mode, and the heat exchange efficiency of the conversion pipe is improved; high-temperature flue gas is introduced from the lower port of the outer sleeve, heat transfer is enhanced by the heat transfer fins to heat the conversion pipe, at the moment, raw material gas enters the U-shaped conversion pipe from the gas inlet and sequentially passes through the straight pipe section, the bent pipe section and the other straig
