Rebar
Deformed Steel Bar Iron Rod 9mm 12 Cheap 12m 14mm 25mm Steel Round Astm Grade 420 Steel Rebar
Bar rolling mostly adopts new processes such as walking beam heating furnace, high-pressure water descaling, low-temperature rolling, and headless rolling. Rough rolling and intermediate rolling are developed to adapt to large billets and improve rolling accuracy. The finishing mill mainly improves accuracy and speed (up to 18m/s).
Walking beam heating furnace → rough rolling mill → intermediate rolling mill → finishing mill → water cooling device → cooling bed → cold shear → automatic counting device → baler → unloading
There are two common classification methods for rebar:
Classification by geometric shape, classification or classification according to the cross-sectional shape of the transverse ribs and the spacing of the ribs. For example, in the British standard (BS4449), rebar is divided into type I and type II. This classification method mainly reflects the gripping performance of rebar.
Classification by performance (grade), for example, in the current implementation standard of my country, rebar is (GB1499.2-2007) and wire is 1499.1-2008), rebar is divided into 3 grades according to strength level (yield point/tensile strength); in the Japanese Industrial Standard (JI SG3112), rebar is divided into 5 types according to comprehensive performance; in the British standard (BS4461), several grades of rebar performance tests are also specified. In addition, rebar can also be classified according to its use, such as ordinary steel bars for reinforced concrete and heat-treated steel bars for prestressed reinforced concrete.
