【Abstract】 The new process of "normalizing+control cooling" or "normalizing+control cooling+tempering" has been developed through a lot of trails and studies using a complete set of introduced heat treatment installation.As the result the difficult problem that the special steel can not reach the set standard due to a drastic loss of strength after the conventional heat treatment is promptly solved and thus a right way to extend functions of the equipments and improve the composite properties of the special steel is open up.更多还原
