AI Technical Summary

Technical Problem

In the continuous casting workshop, high-temperature thin-shell billets lack timely cooling and support at the end of the crystallizer, which easily leads to bulging and deformation, affecting production safety and subsequent processes. The problem is even more pronounced at high casting speeds.

Method used

Design a foot roller and billet water cooling device for a flat billet copper plate crystallizer. By setting two rows of nozzles on the upper and lower sides of the foot roller and arranging them evenly along the length of the foot roller, all-round cooling can be achieved. Combined with billet cooling, cooling is achieved by using a water source, a Y-type filter, cooling water pipes, spray manifolds and nozzles.

Description

Technical Field

[0001] This utility model relates to a foot roller for a flat billet copper plate crystallizer and a billet water cooling device, belonging to the technical field of continuous casting equipment in the metallurgical industry. Background Technology

[0002] In the continuous casting workshop, the copper plate crystallizer for flat billets is an important component of the continuous casting machine. After molten steel is injected into the crystallizer, it comes into contact with the copper plate water tank with water cooling on the crystallizer and is forced to cool, forming a billet shell with a liquid core. The foot rollers set at the end of the continuous casting crystallizer play a guiding and supporting role for the billet. If the high-temperature thin-shell billet exiting the crystallizer is not cooled and supported in time, it is very easy to bulge and deform under the static pressure of molten steel. Therefore, steel leakage often occurs in this section. At the same time, under high casting speed, the thin shell of the billet can be supported and clamped by the foot rollers. Since the billet delamination directly affects the rolling process of the next process, the role of the foot rollers is obvious. The foot rollers and the billet need to be cooled twice. Utility Model Content

[0003] The purpose of this invention is to provide a foot roller for a flat copper plate crystallizer and a water cooling device for the cast billet. By cooling the billet in all directions along the upper and lower sides of the foot roller, the cooling effect is improved. Since the foot roller supports the cast billet and cools it at the same time, the billet is prevented from bulging and deforming, ensuring safe production and smooth progress of subsequent processes, and solving the above-mentioned problems in the background technology.

[0004] The technical solution of this utility model is:

[0005] A foot roller and a billet water cooling device for a flat copper plate crystallizer include a water source, a Y-type filter, a cooling water pipe, a spray manifold, and nozzles. The end of the flat copper plate crystallizer is provided with a foot roller and a supporting billet. The water source is connected to the spray manifold through the cooling water pipe. A Y-type filter is provided on the cooling water pipe. The front end of the spray manifold is provided with two rows of nozzles, and the foot roller is located between the spray lines of the two rows of nozzles. The two rows of nozzles are evenly arranged along the length of the foot roller to cool the foot roller and the billet simultaneously.

[0006] Furthermore, the cooling water pipe includes elbows, rigid pipes, and flexible metal hoses. The two ends of the Y-type filter are respectively connected to the corresponding elbows through rigid pipes, and the spray manifold is connected to the elbow at one end of the Y-type filter through a flexible metal hose.

[0007] Furthermore, the water source is connected to the quick connector protrusion via an inlet plate and a monofilament tube. The quick connector protrusion and quick connector concave head are plugged into and matched. The quick connector concave head is connected to the elbow at the other end of the Y-type filter.

[0008] Furthermore, the Y-type filter is a filter that is known and commonly used in the art.

[0009] The beneficial effects of this utility model are as follows: by cooling in all directions along the upper and lower sides of the foot roller, the cooling effect is improved. Since the foot roller supports the casting billet and cools the casting billet at the same time, the casting billet is prevented from bulging and deforming, thus ensuring safe production and the smooth progress of subsequent processes.
