Problems solved by technology

[0004] 1. The nozzle mixes high-pressure water and sandblasting and then sprays it on the steel surface outside the nozzle. It can only have rust removal effect on the surface of the wire rod facing the nozzle opening, and it needs to be derusted on the surface in other directions. It is necessary to move the nozzle to the top of the corresponding surface, which increases the workload and leads to low efficiency

Abstract

The invention discloses a wire derusting nozzle, which comprises a nozzle body, a high-pressure water spray device and a sand inlet structure; wherein, a first mixing chamber is arranged inside the nozzle body; the sand inlet structure includes a The sand inlet hole; the high-pressure water spray device includes a nozzle seat arranged in the nozzle body, the nozzle seat is provided with a plurality of water spray holes distributed along the circumferential direction, and one end of the water spray hole communicates with the first mixing chamber , the other end communicates with the annular water inlet tank, and the annular water inlet tank communicates with the water inlet pipe; one end of the first mixing chamber is provided with an inlet channel, and the other end is provided with an outlet channel, wherein the diameter of the inlet channel is larger than The diameter of the wire rod forms an annular second mixing chamber between the outside of the wire rod and the inner wall of the wire inlet channel; the diameter of the wire outlet channel matches the wire rod. The rust-removing nozzle for wire rods of the present invention can completely remove surface oxide scales on the surface of wire rods, has high efficiency and is easy to operate.

Description

technical field [0001] The invention relates to wire rod production equipment, in particular to a wire rod derusting nozzle. Background technique [0002] In the production process of hot-rolled steel, the steel ingot is heated to more than 1,000 degrees. The high-temperature steel ingot contacts with air, and an oxidation reaction occurs, forming a layer of oxide scale on the surface of the steel. Iron oxide scale will weaken the corrosion resistance, weldability and mechanical properties of the finished steel, and affect the quality of the steel. [0003] In order to solve the above problems, the utility model patent with the authorized announcement number CN 2425723Y discloses an abrasive high-pressure water phosphorus removal nozzle, which is composed of a high-pressure water supply device and a sandblasting device, and is characterized in that the high-pressure water supply device and the sandblasting device are assembled In the round sleeve, the high-pressure water su...
