Normalizing is the air cooling of a workpiece from above a critical temperature range, and air cooling is one of the normal production processes. The normalizing temperature of the nodular cast iron piston is generally 900 ︒ -930 ︒ ℃, the cooling speed can be changed from static air to large-scale blower blowing, the thick section casting needs a faster cooling speed, and uniform cooling is expected.
In the prior art, the wall thickness of a piston casting is greatly different, the top of the piston casting needs to be rapidly and uniformly cooled to obtain a uniform structure, so that the placing position of a workpiece meets the process requirement during charging, the red hot workpiece cannot be cooled too much during discharging, and otherwise, the red hot workpiece cannot be cooled above the critical temperature range for air cooling. The traditional method is that the workpiece is put into a cradle, so that the tapping time is saved, and the cooling amplitude is reduced as much as possible. However, in the actual tapping process, because the tapping process is in a high temperature state, people are difficult to access, the temperature reduction range is difficult to control, and the service life of the red-hot hanging basket is short, a normalizing heat treatment device for piston processing is urgently needed to solve the problems.
