Steel mill device

Abstract

The invention discloses a steel mill device. The device comprises a bottom plate, wherein side plates are fixedly connected to both sides of the upper surface of the bottom plate, a connecting rod isfixedly connected between two mounting blocks, one side of the outer wall of the connecting rod is fixedly connected with a first limiting ring in a sleeved mode, one side of the first limiting ring is fixedly connected with a fixing pipe, and the exterior of the fixing pipe is rotatably connected with at least three rotating pipes in a sleeve mode; and a fixing seat is connected with a spray head, the middle of the upper surface of the bottom plate is fixedly connected with a liquid collecting plate, the two sides of the liquid collecting plate are fixedly connected with the two side plates separately, a liquid collecting groove is formed in the middle of the liquid collecting plate, and a filter screen is fixedly connected to the bottom of the inner wall of a slag filtering out pipe in asleeve mode. According to the device, the arrangement mode that the rotating pipes are matched with the slag filtering out pipe is used, and the positions of the rotating pipes are thoroughly fixed through the first limiting ring and a second limiting ring so that the spraying angle of the spray head can be adjusted; and metal particles in an emulsion are filtered out through the filter screen, so that multiple utilization of the emulsion is facilitated, and resources are saved.

Description

Technical field [0001] The invention relates to the field of rolling mill devices, in particular to a steel rolling mill device. Background technique [0002] At present, cold-rolled steel strip refers to hot-rolled steel strip and steel plate as raw materials, which are rolled into strip steel and sheet by cold rolling mill at room temperature. The thickness is generally 0.1~3mm and the width is 100~2000mm. The plate has the advantages of good surface finish, good flatness, high dimensional accuracy and good mechanical properties. The cold-rolled strip steel needs to be processed by the cold-rolled strip mill during the production process. [0003] In the processing of steel strip by the steel rolling mill device, the cold-rolled strip rolling mill will use emulsion to spray the surface of the workpiece during processing. However, the following problems will occur when the emulsion sprays the workpiece: [0004] 1. In the spraying process of the emulsion, the spray angle of the ge...

Problems solved by technology

[0004] 1. During the spraying process of the emulsion, the spraying angle of the general spraying head is fixed, and the spraying angle of the spraying head cannot be adjusted, which will cause the belt to be sprayed when the strip is located. The spraying angle of the steel has only one direction, and the emulsion is sprayed onto the steel belt and the rotating roller in the form of a water column, so that the controllability of the distribution of the emulsion spraying area is low, which will cause the spraying of the emulsion to be uneven. Uniformity, which makes the use of spraying less flexible, which in turn makes the use of the emulsion less effective, which makes the processing effect of the strip less effective;

[0005] 2. In the spraying of the emulsion, the emulsion is generally collected, but if the emulsion is collected and reused in this way, some solid metal residues in the emulsion will flow to the steel strip along with the emulsion , so that the metal particle residue stays on the steel strip, which affects the processing of the steel strip
