Description

Technical Field

[0001] The utility model relates to the field of threaded steel production, in particular to a threaded steel descaling machine. Background Art

[0002] Rebar is the common name for hot-rolled ribbed steel bars. Rebar has high strength, good plasticity and weldability, and is suitable for structures that bear large loads and shear forces, such as concrete beams, columns and piles.

[0004] In the above patent, the rebar is passed through a box body, and water is sprayed with a high-pressure nozzle to descale it during the process, and water is recycled to achieve water recycling. However, in actual use, since the rebar is in a high-temperature state when entering the box body, the hardness of the rebar is relatively low. Directly spraying high-pressure cold water on its surface may cause rapid internal cooling and produce certain stress deformation. Moreover, since the position of the nozzle is fixed, although the water it sprays is fan-shaped, its main spraying points are on the upper and lower sides, resulting in uneven descaling.

[0005] Therefore, it is necessary to invent a threaded steel descaling machine to solve the above problems. Utility Model Content
