Factory Cheap Hot Monel Round Bar - Hot rolled steel rebar deformed bar for building construction – Hongmao Detail:
Product introduction
is a surface ribbed steel bar, also known as ribbed steel bar, usually with two longitudinal ribs and transverse ribs evenly distributed along the length direction. The appearance of transverse rib is helical, herringbone, crescent form 3 kinds. In millimeters of nominal diameter. The nominal diameter of ribbed steel bar is equivalent to that of smooth round steel bar with equal cross section. The nominal diameter of steel bar is 8-50 mm, and the recommended diameters are 8, 12, 16, 20, 25, 32, 40 mm. Ribbed reinforcement mainly bears tensile stress in concrete. Ribbed steel bars, due to the role of the rib, and concrete have greater bonding ability, and can better bear the action of external forces. Ribbed steel bars are widely used in various building structures, especially in large, heavy, light thin-walled and high-rise buildings.
Rebar is produced by small rolling mills, the main types of small rolling mills are divided into: continuous, semi-continuous and horizontal. New and in use in the world to the full continuous small mill majority. Popular steel mills are universal high speed rolling steel mills and 4 – section high – volume steel mills. The billet used for continuous small rolling mill is generally continuous casting billet, its side length is generally 130~160mm, the length is generally about 6~12 meters, and the single weight of billet is 1.5~3 tons. Most of the rolling lines are arranged horizontally and vertically alternately to realize the whole line without torsion rolling. There are 18, 20, 22, 24 small rolling mills according to different billet specifications and finished product sizes, 18 as the mainstream. Bar rolling adopts new technology such as stepping heating furnace, high pressure water descaling, low temperature rolling and endless rolling. Rough rolling and middle rolling develop to adapt to large billet and improve rolling accuracy. Finishing mill mainly improves accuracy and speed (up to 18m/s). Product specifications for the general 10-40mm, also have 6-32mm or ф12-50mm. Production of steel for the market demand of low, medium and high carbon steel, low alloy steel; Maximum rolling speed is 18m/s.
Its production process is as follows:
Step heating furnace → roughing mill → medium mill → finishing mill → water cooling device → cold bed → cold shear → automatic counting device → Baling machine → unloading bench. Weight calculation formula: O.O.S. 0.00617=kg/m.
