REBAR ROLLING MILL MACHINE

タイトルまたは説明

Rebar is a surface-ribbed steel bar, named ribbed bar, usually with two longitudinal ribs and transverse ribs that are evenly distributed along the length. The shape of the transverse rib is spiral, herringbone and crescent. The nominal diameter is expressed in millimeters. The nominal diameter of the ribbed steel bar is equivalent to the nominal diameter of the optical steel bar with equal cross section. The nominal diameter of the steel bar is 8 50 mm, the recommended diameter is 8, 12, 16, 20, 25, 32, 40 mm.

Ribbed steel bars are mainly subjected to tensile stress in concrete, and ribbed steel bars have a greater ability to bond with concrete because of the effect of ribs, so they can better withstand external forces. Ribbed steel bars are widely used in various building structures, Especially large, heavy, lightweight thin-walled and high-rise building structures.

Rebar is produced by small-sized rolling mills. The main types are: continuous, semi-continuous, and transverse. At present, most of the newly-built and in-use rolling mills in the world are mostly continuous small rolling mills.

Rebar production process:

(scrap steel melting furnace ,Continuous casting machine,billet heating furnace)step heating furnace→roughing mill→medium mill→finishing mill→water cooling device→cooling bed→cold shear→automatic counting device→bundling machine→cutting material rack.

Characteristics of TMT Quenching System:

●Compact structure, good strength;

●Using a unique scroll type water-cooled, cooling uniform, full, good cooling effect;

●Visual pressure state, according to different rolling process adjust the corresponding pressure, simple operation, easy to observe;

●The lateral movement of the frame adjustable, easy to adjust the line, good performance, handling accidents easy and fast.

●Secondary counterattack water cleaning plant design, good cleaning effect;

●The comprehensive mechanical properties of rolled products increased significantly, beautiful shape, strip straight.
