Technical Field

[0001] The utility model relates to the technical field of steel pipe finishing, in particular to a descaling structure for heat treatment. Background Art

[0002] The descaling design of the quenching furnace is a universal descaling ring of different sizes designed by ourselves for on-site emergency needs. During use, it was found that the descaling and water-blocking effects were not good, and the angle of the descaling nozzle was also problematic. The descaling water was sprayed along the surface of the steel pipe into the furnace, causing damage to the furnace wall.

[0003] Therefore, in order to correct the above-mentioned defects, we propose a descaling structure for heat treatment. Utility Model Content

[0004] The utility model solves the technical problem of providing a descaling structure for heat treatment.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a descaling structure for heat treatment, which includes a water retaining ring and a dephosphorization ring, characterized in that nozzles are distributed in a circumferential manner inside the water retaining ring and the dephosphorization ring, and cylindrical water retaining plates are provided on the sides of the water retaining ring and the dephosphorization ring facing away from each other, the facing sides of the two water retaining plates are in an open state, and the sides of the two water retaining plates facing away from each other have through holes, and the water retaining ring, the dephosphorization ring and the two water retaining plates are connected by two upper and lower connecting rods.

[0006] Furthermore, the nozzles in the water retaining ring are inclined 10° toward the dephosphorization ring.

[0007] Furthermore, the nozzles in the dephosphorization ring are inclined 10° toward the water retaining ring.

[0008] Furthermore, the nozzles in the water retaining ring are successively inclined 15° along the inner ring direction of the water retaining ring.

[0009] Furthermore, the nozzles in the dephosphorization ring are sequentially inclined at 15° along the inner ring direction of the dephosphorization ring.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] The utility model provides a technical solution:

[0019] See also Figure 1-4 A descaling structure for heat treatment is composed of a water retaining ring 2 and a dephosphorization ring 3. The water retaining ring 2 and the dephosphorization ring 3 are connected to the same water inlet pipe. The outer diameter size of the descaling ring 3 and the number of descaling nozzles are redesigned according to the outer diameter size of the steel pipe and the effective striking distance of the nozzle 4 to achieve 360° descaling on the surface of steel pipes of different specifications. Therefore, a large number of nozzles 4 are distributed in an annular manner in the water retaining ring 2 and the dephosphorization ring 3.

[0020] The angle of the nozzle 4 in the water retaining ring 2 and the dephosphorization ring 3 is designed to be changed from 15° vertically inward to 10° inward, and the nozzle 4 is tilted 15° along the annular direction in sequence, which meets the on-site descaling effect while reducing the splashing force of the descaling water.

[0021] In addition, a cylindrical water retaining plate 1 is provided on the side opposite to each other of the water retaining ring 2 and the dephosphorization ring 3. In addition to the water retaining ring 2 having a water retaining effect, the water retaining plate 1 is added to prevent the dephosphorization water from splashing into the furnace and causing damage to the furnace wall. The two water retaining plates 1 have a through hole on the side opposite to each other, and the hole is used for the steel pipe to pass through.

[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
