Description

Technical Field

[0001] The utility model relates to the technical field of high-speed wire production in the metallurgical industry, in particular to a layered placement rack for roughing and intermediate rolling rollers of a high-speed wire rolling mill. Background Art

[0002] The high-speed wire rod mill is the main type of rolling mill currently used in the production of major wire rod products in China. Its main production process includes billet loading, heating, rough rolling, intermediate rolling, pre-finishing rolling, finishing rolling, water cooling, laying out, Stelmor air cooling line, coiling, P / F line, trimming, packaging, weighing, coil unloading, and storage.

[0003] Rollers are the most important production tools and key components in high-speed wire rod mills. During the rolling process, the rolls come into direct contact with the workpiece and, under certain rolling conditions, cause plastic deformation of the workpiece, ultimately achieving a product shape and dimensional accuracy that meets standard requirements. Roller operating conditions are extremely harsh, so the roll's design strength and material, as well as its in-line layout, installation, and maintenance, directly impact its service life and condition. The basic roll structure consists of three parts: the barrel, the roll head, and the roll head. The barrel is the working part where the roll directly contacts the workpiece. The barrel is a cylindrical structure with grooves machined into it. The roll head is the supporting part of the roll, supported by the roll head on bearings on both sides. The intersection of the barrel and the roll head is designed with an over-radius due to the cross-sectional change, which makes it prone to fracture. The roll head is used to transmit torque. It mates with the connecting shaft and is generally manufactured with a flat head or a plum head. The roller shape is mainly cylindrical, which makes it difficult to store. If placed flat on the ground, it occupies a large area and is prone to rolling, posing a safety risk. Therefore, the present invention provides a layered placement rack for coarse and medium rolling rollers of a high-speed wire rolling mill to solve the above problems. Utility Model Content
