Description

Technical Field

[0001] This utility model relates to the field of stainless steel pipe cooling technology, specifically a stainless steel pipe production cooling device. Background Technology

[0002] Steel pipes are formed by winding steel strips and then welding the seams together. During the welding process, a large amount of heat is generated, and appropriate cooling devices are needed to prevent the steel pipes from deforming. Currently, air cooling, or natural cooling, is used to cool the steel pipes. This method is suitable for austenitic stainless steels with poor thermal conductivity (such as 316L), but the cooling rate is slow (it takes more than 20 minutes to drop to 40°C), which can easily lead to grain coarsening.

[0003] Therefore, it is particularly important to design a cooling device for stainless steel pipe production to overcome the above-mentioned technical defects and improve overall practicality. Utility Model Content

[0019] In this embodiment, the air outlet of the cooling fan 7 is connected to a fixed air blowing pipe 701, the top end of the fixed air blowing pipe 701 is connected to a telescopic pipe 702, the top end of the telescopic pipe 702 is connected to a movable air blowing pipe 703, the left ends of both the fixed air blowing pipe 701 and the movable air blowing pipe 703 are connected to a semi-curved cooling cover 704, the inner side of the semi-curved cooling cover 704 is evenly provided with air outlets 705, the inner side of the semi-curved cooling cover 704 and the position of the temperature sensor 706 is evenly installed on the inner side of the semi-curved cooling cover 704 and away from the air outlets 705, and an electric push rod 707 is installed on the top of the cooling fan 7. Stainless steel pipes are installed between multiple sets of steel pipe guide wheels 5. Two sets of semi-bent cooling covers 704 are located on the upper and lower sides of the stainless steel pipes, respectively. A control switch is installed on the outside of the mounting frame 1.

The cooling fan 7 transmits cold air through the air outlet to the inside of the fixed air pipe 701 and the movable air pipe 703, and then through the semi-curved cooling cover 704 on the surface of the steel pipe. The surface temperature can be monitored by the temperature sensor 706, thus finally cooling one section of the steel pipe. After cooling, it can be conveyed again and the cooling operation can continue.
