The invention relates to a method for controlling cooling after a
forging steel part is forged, and belongs to the field of steel
forging and heat treatment. The method is characterized in that a forged workpiece is immerged into a uniform-speed
cooling medium for cooling; a cooling process takes the fact that a non-equilibrium
state structure is not generated on a surface as a principle and can adopt a cooling mode of cooling to proper temperature and then equalizing the temperature or other cooling
modes according to the size of a material and a workpiece. The method for controlling cooling after
forging, which is disclosed by the invention, can solve the problems of rough and large structure, hereditary structures, such as a banded structure, and structure nonuniformity of the traditional forging stock, ensure the rigidity uniformity of the forging stock, impulse the popularization of a dry
cutting technology, improve the mechanical properties, namely
anisotropy,
impact ductility and the like of a product which is subjected to heat treatment, improve the uniformity of a structure which is not subjected to the heat treatment and effectively cooperate with the heat treatment
deformation control.
