Hot rolling manufacturing process for deformed steel bars

Abstract

The invention relates to a hot rolling manufacturing process for deformed steel bars. A main plate, a conveying device, a heating furnace, a profiling device and a molding device are included; the conveying device is installed at the upper end of the main plate; the heating furnace is arranged on the right side of the conveying device; the heating furnace is installed on the main plate; the profiling device is arranged on the right side of the heating furnace; the profiling device is installed on the main plate; and the molding device is arranged on the right side of the profiling device. The hot rolling manufacturing process for the deformed steel bars can solve the problems that when existing equipment carries out compressing molding on the deformed steel bars, secondary compressing treatment cannot be carried out on the steel bars, the phenomenon of incomplete molding easily occurs after the steel bars are compressed, the success rate of deformed steel bar molding is reduced, meanwhile, the molded deformed steel bars cannot be corrected, the steel bars are prone to excessive deformation during compressing, it cannot be guaranteed that the steel bars are kept in a straight state during compressing, the deformed steel bars molded through compressing are prone to bending, and the deformed steel bar molding effect is reduced are solved.

Description

technical field [0001] The invention relates to the technical field of steel material processing, in particular to a hot-rolled manufacturing process of rebar. Background technique [0002] Rebar is a steel bar with ribs on the surface, also known as ribbed steel bar. It usually has 2 longitudinal ribs and transverse ribs evenly distributed along the length direction. The shapes of the transverse ribs are spiral, herringbone and crescent. The ribs on the surface are usually processed by hot rolling process. Rebar is a must-use steel for medium-sized and above building components. Due to the role of ribs, rebar has a greater bonding capacity with concrete, thus increasing the ability to withstand external forces. Therefore Rebar is widely used in various building structures, especially large, heavy, light thin-walled and high-rise building structures. [0003] At present, the existing equipment usually has the following deficiencies when the rebar is pressed and formed: 1. T...

AI Technical Summary

Problems solved by technology

[0005] The invention can solve the problem that the existing equipment cannot carry out secondary pressing treatment on the steel bar when the rebar is pressed and formed, and the steel bar is prone to incomplete forming after pressing, thereby reducing the effect of rebar forming and reducing the rebar forming effect. At the same time, the rebar after forming cannot be rectified, and the rebar is prone to excessive deformation during pressing, and it cannot be ensured that the rebar is kept straight during pressing, and the rebar after pressing is prone to bending phenomenon, thereby reducing the effect of rebar forming and other problems
