Abstract
Description
Technical Field

[0002] The high-speed wire rod rolling mill production line is the main machine model currently used in the production of high-speed wire rods. Its main production process flow is billet loading, heating, rough rolling, intermediate rolling, pre-finishing rolling, finishing rolling, water cooling, wire drawing, Stelmor air cooling line, coiling, trimming, packaging, weighing, unloading and warehousing. The main function of its rough and intermediate rolling unit is to perform a large amount of reduction on the raw billet to provide preliminary formed qualified billets for pre-finishing rolling. Since the raw billet has uneven temperature on the four end faces of the square billet in the heating furnace, and the rolling speed is slow and the temperature drops quickly during the rough and intermediate rolling production process, the temperature drop of the four end faces is also different. Therefore, the deformation of the rolled piece is large. In order to prevent it from warping, it will be used in conjunction with an anti-warping guide groove.
[0003] During use, the existing anti-warping guide groove is often insufficient in the limit components. During rough and intermediate rolling, due to the large temperature difference between the upper and lower end surfaces of the rolled piece, uneven wear of the upper and lower rolling grooves, non-standard outer diameters of the upper and lower rolls, deviation of the inlet and outlet guides from the rolling line, large clearance between the drive shaft and the flat head of the roll, large gap between the roll gaps on both sides of the rolls, and large clearance between the rolls and the arch, the rolled piece will warp up, down, left or right after being rolled by the rolls, and cannot smoothly enter the entrance guide of the next rolling mill, resulting in steel piling accidents. Therefore, a high-speed wire rod mill roughing unit anti-warping guide groove is proposed for the roughing unit. Utility Model Content
