High-pressure water descaling jetting device

Abstract

The invention discloses a high-pressure water descaling jetting device. The device comprises an upper water collecting pipe and a lower water collecting pipe, wherein a left end of the upper water collecting pipe is connected with an upper water connector component, and a right end of the upper water collecting pipe is connected with an upper end cover which is arranged on an upper bracket; the left end of the lower water collecting pipe is connected with a lower water connector component, and the right end of the lower water collecting pipe is connected with a lower end cover which is arranged on a lower bracket; the upper water connector component can be connected with a left support through a left lifting mechanism in an up-and-down moving manner, and the upper bracket is connected witha right support through a right lifting mechanism in an up-and-down moving manner; each of the upper water collecting pipe and the lower water collecting pipe are connected with a quick detaching mechanism; and an upper nozzle is provided with a protective separation blade. According to the high-pressure water descaling jetting device disclosed by the invention, the descaling effect is effectively improved, rapid maintenance is facilitated, and meanwhile the service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of metallurgy, and in particular relates to a high-pressure water descaling injection device. Background technique [0002] In the rolling process of strip steel, it is necessary to remove the scale on the upper and lower surfaces of the slab by high-pressure water, that is, descaling. Most of the descaling equipment includes upper and lower water collection pipes and nozzles arranged on the water collection pipes. In actual production, there are certain defects in the descaling equipment used in the existing production line: first, the height of the upper water collection pipe is constant, and it is difficult to achieve the same descaling effect for slabs of different thicknesses; The joints are connected by flange bolts, so it is difficult to install and disassemble. Third, the nozzles lack effective protective measures, which often cause damage to the nozzles. The above situation has a certain impact on t...
