Description

Technical Field

[0001] This utility model relates to the field of roughing mill technology, specifically to a roughing mill. Background Technology

[0002] With the vigorous development of steel enterprises, the trend towards high-speed, continuous, and high-yield wire rod production is inevitable. Controlled cooling technology for bars, as a necessary means to improve steel performance and ensure steel quality, is increasingly widely applied in bar production. Controlled rolling and controlled cooling processes are among the fastest-developing technologies in the metallurgical industry. In the past, rolling improved steel performance by adding alloying elements and post-rolling heat treatment. Controlled rolling, however, controls the deformation during hot rolling and the cooling rate of the steel after rolling, fully refining the grain size, improving the steel's microstructure, and thus enhancing its overall performance. By adopting controlled rolling, production costs can be reduced. By controlling the post-rolling cooling rate, grain refinement is achieved, resulting in reduced strength and hardness, increased plasticity and toughness, and improved processing performance.

[0003] In the existing technology, when roughing mills are in use, some large-diameter round bars are too large, which causes the internal cooling system of the equipment to be unable to cool and dissipate heat evenly on the outside of the large-diameter round bars. This results in a large temperature difference on the outside of the large-diameter round bars, which reduces the processing effect of the roughing mill on the large-diameter round bars.
