Multi-stage anti-blocking non-return high-regulation-ratio high-atomization double-medium long-acting nozzle

Abstract

The invention relates to the technical field of metallurgical continuous casting, in particular to a multi-stage anti-blocking non-return high-regulation-ratio high-atomization double-medium long-acting nozzle. In order to solve the problem that the quality of a casting blank is affected due to the fact that the spraying angle is reduced along with the change of pressure due to insufficient pressure in the spraying process of an existing metallurgical continuous casting nozzle, the multi-stage anti-blocking non-return high-regulation-ratio high-atomization double-medium long-acting nozzle comprises a nozzle body, a nozzle rod and a nozzle head, the nozzle body is provided with an air passing hole and a water passing hole, and the nozzle rod comprises an inner pipe, a non-return device, an outer pipe and a connecting body; and the nozzle head is connected with the connecting body. According to the technical scheme, reserve pressure can be generated when water flow passes through, the purposes of energy storage and pressurization of the nozzle are achieved, the phenomenon of pressure attenuation of the nozzle is effectively avoided, the overall working efficiency and the water flow spraying strength of the nozzle are improved, and the working stability of a water spraying hole is improved.

Description

technical field [0001] The invention relates to the technical field of metallurgical continuous casting, in particular to a multi-stage anti-blocking and anti-return nozzle with large adjustment ratio and high atomization dual-media long-term effect. Background technique [0002] The nozzle is a key component in various spraying, spraying, oil spraying, sandblasting, spraying and other equipment, which plays an important role. The nozzle is widely used in the industry. Among them, in the field of metallurgical continuous casting, the nozzle It plays a vital role. [0003] In the field of metallurgical continuous casting, the stability of the water pressure has a great influence on the quality of the slab. The existing nozzles are greatly affected by the water pressure. The rear part of the slab has serious temperature recovery, and the increase of oxide scale affects the quality of the slab, so there is a need for improvement, and the current nozzle is relatively rough due ...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problem that the existing nozzles for metallurgical continuous casting are greatly affected by water pressure, and the pressure in the nozzle is insufficient during the injection process, so that the injection angle becomes smaller with the change of pressure, the water output decreases, and the quality of the slab is affected;
