A kind of screw steel hot rolling manufacturing process

Abstract

The invention relates to a hot-rolled manufacturing process of rebar, including a main board, a conveying device, a heating furnace, a pressing device and a molding device, a conveying device is installed on the upper end of the main board, a heating furnace is arranged on the right side of the conveying device, and the heating furnace is installed on the main board On the right side of the heating furnace, there is a profiling device installed on the main board, and on the right side of the profiling device is a molding device. The present invention can solve the problem that the existing equipment cannot carry out secondary pressing treatment on the steel bar when pressing and forming the threaded steel, and the steel bar is prone to incomplete forming after pressing, which reduces the success rate of the threaded steel forming, and at the same time, cannot The formed rebar is rectified, and the rebar is prone to excessive deformation during pressing, and it cannot be ensured that the rebar remains straight during pressing. effects and other issues.

Description

A kind of hot rolling manufacturing process of rebar technical field [0001] The present invention relates to the technical field of steel processing, in particular to a manufacturing process for hot rolling of rebar. Background technique Rebar is a ribbed steel bar on the surface, also called ribbed steel bar, usually with 2 longitudinal ribs and uniform along the length direction. Distributed transverse ribs, the shapes of transverse ribs are spiral, herringbone, and crescent shapes. The ribs on the surface of rebar are usually hot-rolled. Process, rebar is a medium-sized and above construction component must be made of steel, due to the action of ribs, rebar is different from concrete. Larger bonding capacity, thus increasing the ability to withstand external forces, so rebar is widely used in various building structures, especially Large, heavy, light thin-walled and high-rise building structures. At present, when existing equipment is pressed and formed for reb...

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
