Description

Technical Field

[0001] The utility model relates to the technical field of casting, in particular to a forced cooling device after normalizing. Background Art

[0002] In the casting field, many large castings can be directly air-cooled and normalized on the heat treatment furnace trolley. However, for products with high mechanical property requirements such as substrates, the cooling speed of normal air-cooled normalizing is not fast enough to achieve the cooling speed that meets the mechanical properties. It is necessary to use a heat treatment method that forces cooling of the workpiece during normalizing to meet the requirements.

[0003] The publication (announcement) number is CN204417550U, which discloses a heat treatment strong spray device, including an axial flow fan, a water pipe is fixed in the horizontal diameter direction of the axial flow fan outlet, one end of the water pipe is sealed, and the other end is connected to high-pressure water, and seven special nozzles are evenly distributed on the upper end of the water pipe. When working, the axial flow fan is started first, and then the high-pressure water switch is turned on. The water flows through the water pipe and flows out from the special nozzle to form an atomized state. Under the push of wind, it is sprayed to the workpiece to be normalized, which has the effect of forced cooling. After using this device, the cooling speed of the workpiece is much higher than the speed of blowing cooling, which is conducive to processing high-requirement heat treatment parts and improving the qualified rate. It has the characteristics of ensuring the heat treatment cooling effect of the casting and ensuring that the heat treatment equipment will not be seriously damaged.

[0004] Although the above scheme can achieve the effect of forced cooling by combining air cooling with atomized water flow spraying onto the workpiece, the water pipe and nozzle position of the atomized water flow are fixed, and the uneven spraying of the water mist can easily cause uneven cooling effect, and the sprayed atomized water is easy to scatter everywhere and is difficult to collect. For this reason, we propose a forced cooling device after normalizing. Utility Model Content
