Description

Technical Field

[0001] The utility model belongs to the technical field of steel bar production, and specifically relates to a hot-rolled steel bar production device. Background Art

[0002] At present, in the production process of hot-rolled steel bars, the steel billets are usually first heated by a heating furnace and then transported to a hot rolling mill for hot rolling. After hot rolling, the hot-rolled steel bars are output for cooling. After cooling, they are cut and then packaged and transported.

[0003] However, hot-rolled steel bars are generally long, especially those with a diameter of 10-40 mm, which are basically 6-12 meters long. When the hot-rolled steel bars are sent for slitting, the slitting equipment can only fix the hot-rolled steel bars on the workbench, that is, the front end of the steel bars, due to its limited length, while the rear end of the steel bars is suspended in the air and will bend downward under the action of gravity, or even deform, which will affect the cutting of the entire hot-rolled steel bar to a certain extent, resulting in an increase in cutting errors; in addition, the existing slitting equipment generally uses tools such as measuring rulers to cut the hot-rolled steel bars at equal distances during slitting, and each cut needs to be re-measured, which is more troublesome to operate; in addition, the cutting tool will be worn or rusted due to long-term use or improper maintenance, which will also cause unevenness or burrs at the steel bar cut, affecting the steel bar joints and reducing product quality.

[0004] For this reason, a hot-rolled steel bar production device is badly needed. Utility Model Content
