            In terms of heat treatment process, the car bottom furnace and bell type furnace have been developed into continuous controllable atmosphere annealing furnace. At present, the length of continuous heat treatment furnace is 150m, and the spheroidized structure of seamless steel pipe for high pressure boiler is stable and uniform. The decarburization layer is small and the energy consumption is low. Since the 1970s, with the economic development and industrial technology progress.
