Rapid air cooling chamber for isothermal normalizing

Abstract

The invention discloses a rapid air cooling chamber for isothermal normalizing. The rapid air cooling chamber for isothermal normalizing comprises an air cooling chamber body (1), a feed door (2), a discharge door (3), a feed door lifting mechanism (2-1), a discharge door lifting mechanism (3-1) and a centrifugal fan (5), wherein feed door (2) and the discharge door (3) are formed in the air cooling chamber body, the feed door lifting mechanism (2-1) controls the feed door to be opened and closed, the discharge door lifting mechanism (3-1) controls the discharge door to be opened and closed, the bottom portion of the air cooling chamber body and the top portion of the air cooling chamber body are provided with an air inlet pipeline (7) and an air outlet pipeline (4) respectively, the air outlet pipeline is divided into two ways after passing though the centrifugal fan, one way is directly communicated with the atmosphere through an exhaust duct (8), the other way is connected with the air inlet pipeline through a return air duct (9), and a turning plate adjusting mechanism (10) which is used for changing the air flow direction is arranged at the joint of the exhaust duct and the return air duct. The rapid air cooling chamber for isothermal normalizing has the advantages that the workpiece cooling speed is even, the temperature differences among all parts of a workpiece are small, and the rapid air cooling chamber is simple in structure and convenient to use and operate.

Description

technical field [0001] The invention relates to a rapid air cooling chamber for isothermal normalizing. Background technique [0002] The traditional fast air cooling chamber uses a centrifugal fan to blow cold air to the heated metal workpiece to cool the workpiece to a predetermined process temperature. [0003] The traditional fast air cooling chamber includes: a cooling chamber body, a material inlet door and a lifting mechanism, a material outlet door and a lifting mechanism, a centrifugal fan, an air inlet duct, and an exhaust duct. [0004] The working process of the traditional fast air cooling chamber is as follows: the feeding door is opened, and the workpiece is transferred from the heating furnace to the fast air cooling chamber; the feeding door is closed, the centrifugal fan is turned on, and the cold air is blown into the air cooling chamber from the air inlet pipe. The workpiece is cooled, and the air after heat exchange is discharged from the exhaust pipe; ...

AI Technical Summary

Problems solved by technology

[0005] Due to the use of blowing cooling, the traditional fast air cooling chamber cannot uniformly cool all the workpieces due to the wind resistance of the pipeline and the obstruction of the airflow by the workpiece, resulting in uneven temperature of different workpieces; the temperature of the windward side of the workpiece drops quickly, and the temperature of the leeward side drops slowly, resulting The uneven temperature of the same workpiece affects the product quality of the workpiece
