Abstract
Description
Technical Field
[0001] This utility model relates to the field of bar rolling technology, specifically a bar rolling device. Background Technology
[0002] Bar stock generally refers to a material product with a simple cross-sectional shape such as round, square, hexagonal, or octagonal, a relatively large length relative to its cross-sectional size, and is usually provided in straight strips. It is a pressure processing method where metal billets are passed through the gap (of various shapes) of a pair of rotating rolls. Due to the compression of the rolls, the material's cross-section decreases and its length increases. This is the most common production method for steel, mainly used to produce profiles, plates, and pipes. It is divided into hot-rolled and cold-rolled types.
[0003] Bar stock has a wide range of applications. It is formed from metal billets. To improve processing efficiency, the billet needs to be heated to reduce its strength, facilitating its passage through rolls and enabling processing. Therefore, a rolling mill is needed to improve the efficiency of bar stock processing. Utility Model Content
