Description

Technical Field

[0001] The utility model relates to the technical field of wire rod rolling mills, in particular to a rough and medium rolling empty passing guide tube for a high-speed wire rod rolling mill. Background Art

[0002] A wire rod rolling mill is a rolling mill specifically used for rolling wire rods (i.e., wire). Wire is the product with the smallest cross-sectional size among profiles. From the billet to the finished product, the total elongation coefficient is large, and the rolled piece is often only rolled once on each rolling mill. Therefore, the wire rod rolling mill has the most stands and the most detailed division of labor among hot-rolled profiles.

[0003] Referring to the patent document with the publication number CN215879262U, a medium rolling empty passing tube for a high-speed wire rod rolling mill is disclosed. The outer wall of the empty passing tube is cylindrical, and the inside includes a hollow tube cavity; one end of the hollow tube cavity is in a flared shape, and the straight tube cavity is connected to the flared shape; the bottom of the straight tube cavity includes 1 to 10 water channels, and the bottom end of the water channel includes a slot hole, and the slot hole penetrates through the outer wall of the empty passing tube and is connected to a drainage device; the medium rolling empty passing tube for the high-speed wire rod rolling mill of the utility model collects the redundant cooling water by using the water channels, effectively avoiding the defect problems of the influence on the hot inspection signal and inaccurate temperature detection caused by the accumulation of cooling water at the outlet end of the empty passing tube; it can be applied to the transformation of the empty passing tubes of various types of rolling mills, and has good applicability.

[0004] Although the above solution can guide the cooling water during use, there are still some deficiencies in the process of use. For example, during use, it is difficult to scrape the surface of the rolled piece passing through, resulting in residual cooling water during drainage, which affects the hot inspection signal. Therefore, a rough and medium rolling empty passing guide tube for a high-speed wire rod rolling mill is proposed to solve the above problems. Summary of the Utility Model

[0028] In this embodiment, a drainage cotton column 8 is provided on the inner wall of each drain hole 4, and the top end of each drainage cotton column 8 is in contact with the outer surface of the sponge ring 6. Through the drainage cotton column 8, the water inside the sponge ring 6 can be guided, so that the water can be quickly discharged.
