Description

Technical Field

[0001] The utility model relates to the technical field of steel bar production, in particular to a high-efficiency phosphorus removal device for cold-rolled ribbed steel bars. Background Art

[0002] Cold-rolled ribbed steel bars are made from hot-rolled wire rods that undergo multiple cold-rolling steps to reduce the diameter, a rib compression step, and internal stress relief. They are crescent-shaped bars on two or three sides. Cold-rolled ribbed steel bars are an alternative to cold-drawn low-carbon steel wire in prestressed concrete components. However, cold-rolled ribbed steel bars require dephosphorization during production. Descaling involves removing the iron oxide scale to prevent it from penetrating the surface and causing defects, thereby improving the surface quality of the product.

[0003] Utility model application number CN202022894678.2 discloses a highly efficient descaling device for cold-rolled ribbed steel bars. A first motor drives a conveyor roller to rotate, thereby conveying the material. A high-pressure water pump sprays water to descale the material surface. A descaling gear roller improves descaling efficiency.

[0004] The above device descales the surface of the material by spraying water and dephosphorization gear rollers. The two dephosphorization gear rollers can only contact the upper and lower surfaces of the steel bar, and the high-pressure nozzle cannot spray water on the side of the steel bar. When dephosphorizing, the iron oxide scale on the side of the steel bar cannot be completely removed. The iron oxide scale is not removed cleanly, which reduces the dephosphorization effect and affects the production quality of the steel bar. Only one steel bar can be dephosphorized, and the work efficiency is low.

[0005] It should be noted that the above content falls within the technical knowledge of the inventor and does not necessarily constitute prior art. Utility Model Content

A rotating motor is installed on the fixed bracket, and a driving sprocket is installed on the output end of the rotating motor. The driving sprocket and the driven sprocket are connected by a chain, and a plurality of guide grooves are provided on the conveying roller.

The lower wire roller and the upper wire roller contact the material and can completely wrap the material, which can completely remove phosphorus from the surface of the material and improve the removal effect. At the same time, the top spray plate sprays water to clean the dust remaining after dephosphorization, which improves the cleaning effect.
