Description

Technical Field

[0001] The utility model belongs to the technical field of descaling of small square billets, and more specifically relates to a swing descaling spray gun device for small square billets. Background Art

[0002] Iron oxide scale (scale) forms on the surface of steel billets at high temperatures. This scale causes defects such as pitting, iron oxide, and pits, which affect product quality. To address this, descaling is necessary. Currently, two common methods for descaling square billets are high-pressure water jetting and mechanical descaling. Mechanical descaling is prone to damage to the steel surface, is inefficient, and results in significant roughness, making it less widely used. High-pressure water jet descaling offers advantages such as adaptability to a wide range of steel grades, high removal efficiency, and low overall cost.

[0003] Based on the above, the inventors found that the following problems exist: a jet water gun is usually used to descale small square billets, but the jet water gun is currently installed in a fixed spray position. When the steel billet to be descaled passes the descaling point, the high-pressure water generated by the high-pressure pump station forms a high-speed jet through the nozzle, and the scales on the surface are peeled off under the impact of the water flow. This form of descaling has a low fault tolerance rate. When the steel deviates, the descaling effect will be reduced and the surface quality of the steel will be affected.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a small square billet swing descaling spray gun device is provided, in order to achieve the purpose of having more practical value. Utility Model Content

[0012] Further, the support circular pipe and the fixed bottom plate, the support circular pipe and the motor support, and the pull rod and the driving assembly are detachably connected.
