Description

Technical Field

[0001] The utility model relates to the technical field of high-speed wire rod rolling mills in iron and steel metallurgy, and particularly relates to a live-loop bypass conduit on the front side of a finishing mill unit of a high-speed wire rod rolling mill. Background Technique

[0002] Wire rod products are one of the important varieties of iron and steel metallurgy products. There are more than 700 types of steel grades and specifications, which are widely used in various aspects of national economic construction, such as engineering construction and the metal products industry, etc. According to the operating characteristics of a high-speed continuous rolling production line, the finishing mill unit is one of the most core equipment of a high-speed wire rod rolling mill. Its main function is the final rolling tool, which precisely shapes the rolled piece provided by the pre-finishing mill unit to meet the required final product size and dimensional accuracy requirements. To ensure the through-strip uniformity of the rolled piece size, a side live loop is generally designed between the pre-finishing mill unit and the finishing mill unit to achieve tension-free rolling between the pre-finishing mill unit and the finishing mill unit.

[0003] The existing side live-loop bypass conduit not only has a high cost, but is also inconvenient to replace during use. At the same time, it cannot guide the direction of the head of the red-hot steel and prevent the tail from whipping. The rolled piece is prone to contact with the conduit, making the conduit prone to damage. For this reason, we propose a live-loop bypass conduit on the front side of a finishing mill unit of a high-speed wire rod rolling mill. Content of the Utility Model

At the same time, it cannot guide the direction of the head of the red-hot steel and prevent the tail from whipping. The rolled piece is prone to contact with the conduit, making the conduit prone to damage.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A live-loop bypass conduit on the front side of a finishing mill unit of a high-speed wire rod rolling mill, including a conduit body.
