High-speed wire mill vertical guide roller

Technical field
The utility model relates to a guide roller used in a metallurgical rolling steel device, in particular to a vertical guide roller of a high speed wire rod rolling mill.

Background technique
In order to solve the problem of scratching the surface of the rolling stock on the high-speed wire rolling mill, the horizontal guide roller is usually used. However, since the high-speed wire is curved in the guide groove, the guide groove arm often has a surface on the rolled piece. Scratches, rolling parts often produce unilateral ears, affecting product quality. Especially in the production of high-cold-free performance-free annealing, simple annealing, and non-tempered steel and other value-added products, the rolling process requires a very high shape of the strip shape of the rolling stock, and the fine crack of 0.05mm on the finished product may cause the product to be cold. The performance of the crucible is unqualified, that is, the strip in the middle rolling zone has more than 0.2mm scratches, which is reflected in the finished product as a compressive crack. The finished product that is rolled out may be waste products, which may easily cause mass quality accidents. In actual production, the guide groove arm is smooth and the wider guide groove is used to solve the problem of scratching the surface of the rolling piece by the guide arm. This not only increases the equipment cost, but also completely solves the problem of the guide arm to the surface of the rolled piece. Scratch problem; in the actual production process, the horizontal guide roller is also set up vertically to solve the problem of scratching the surface of the rolling member by the guide arm, but the bearing is slid down due to the weight of the bearing itself. The bearing is damaged and the guide roller does not work.

Summary of the invention
The purpose of the utility model is to provide a high-speed wire rolling mill vertical guide roller in view of the deficiencies of the prior art. In order to achieve the above object, the technical solution adopted by the utility model to solve the technical problems thereof is as follows: a high-speed wire rolling mill vertical guide roller, including a roller surface, a roller shaft, a bearing, and the bearing is set on a roller shaft, the stick A bearing limit retaining ring is also provided on the shaft. A bearing cover is arranged at the joint between the roller surface and the roller shaft, and a sealing gasket is arranged inside the bearing cover. The bearing is a deep groove ball bearing. When the high-speed wire moves in an arc in the guide groove, because the vertical guide roller is provided, the high-speed wire does not contact the guide arm, the guide arm does not scratch the surface of the rolled piece, and the rolled piece does not produce a single-sided ear. The vertical guide roller of the high-speed wire rod mill of the utility model fixes the bearing through the bearing limit retaining ring, solves the bearing slip and sets the bearing cover, and the bearing lubricating oil does not quickly evaporate due to the high temperature of the working environment, ensuring the standing The guide roller can work for a long time without being damaged. The utility model has the advantages that the problem of scratching and bearing sliding on the surface of the rolled piece is solved, the quality of the wire is improved, the production cost is reduced, the damage is not easy, and the service life is long.
