To the problem of the unstable performance of the normalized train shafts due to seasonal temperature difference ,a control cooling technology was proposed .The compressed air was blown onto the surface of train shafts after secondary nomalizing ,the cooling rate of the nomalized shafts was controlled by adjusting the air velocity on the nozzle outlet ,and the problem was solved .
