[0002] As a form of effective utilization of clean energy, wind power generators are popularized and used by countries all over the world. The wind power main shaft is one of the key components of wind power generators. The traditional cooling process is water quenching oil cooling. The process has become mature and has achieved However, in actual production, a large amount of oil fume will be generated when the forgings are lifted out of the oil pool after cooling. In today's environment with high pressure on environmental protection, a clean and reliable quenching method is the general trend of the heat treatment industry.

The invention discloses a heat treatment method of a wind power spindle. The heat treatment method comprises the steps of: S1, heating the forging formed wind power spindle to 850-870 DEG C and then conducting heat preservation treatment; S2, immersing the wind power spindle after heat preservation treatment into water for cooling, and then taking out the wind power spindle after 15-25 minutes andplacing the wind power spindle in air for cooling; S3, when the surface temperature of the wind power spindle returns to 250-300 DEG C, putting the wind power spindle into water for cooling, and thentaking out the wind power spindle after a set time and placing the wind power spindle in air for air cooling; and S4, repeating S3 until the wind power spindle returns to the temperature in air afterthe set time is below 200 DEG C. According to the heat treatment method for the wind power spindle, in the process of the heat treatment process of the wind power spindle, only water vapor is generated, no oil fume is generated in the whole process. At the same time, the wind power spindle manufactured by the heat treatment method of the wind power spindle can achieve the same performance of water quenching and oil cooling.
Description
technical field [0001] The invention relates to the field of forging heat treatment, in particular to a heat treatment method for a wind power main shaft. Background technique [0002] As a form of effective utilization of clean energy, wind power generators have been popularized and used by countries all over the world. The wind power main shaft is one of the key components of wind power generators. The traditional cooling process is water quenching oil cooling. The process has become mature and has achieved However, in actual production, when the forgings are cooled and lifted out of the oil pool, a large amount of oil fume will be generated. Under the current environmental protection pressure, a clean and reliable quenching method is the general trend of the heat treatment industry. Therefore, it is necessary to provide a heat treatment method for the wind power main shaft, so as to replace the original water quenching and oil cooling method, and to eliminate the problem ...
