Bending Welding Hot Rolled Black Carbon Steel Coil SS400 Q235 Q345 MS ISO ASTM

Product Description:

Hot-rolled steel plate with rolling slab or primary slab for raw materials, heated by the step heating furnace, high-pressure water descaling into the roughing mill, rough rolling material by cutting the head, tail, and then into the finishing mill, the use of computer programs to regulate rolling, the final rolling that is after the laminar flow cooling (computer-controlled cold speed) and winding machine, into a straight hair volume.

Straight hair volume of the head, tail is usually tongue and fish tail-shaped, thick and thin, width precision is weak, the edge often has wave-shaped, bending, tower-shaped and other shortcomings. Its volume weight is heavy, volume steel inner diameter of 760mm. Will straight hair volume by cutting head, cutting tail, cutting edge and multiple straightening, leveling and finishing line processing, and then cut plate or re-roll, that is: hot-rolled steel plate, leveling hot-rolled steel coil, longitudinal strip and other commodities.

Hot-rolled finishing volume if the pickling passivation to remove oxidation and oiling after both into hot-rolled pickled plate volume. The commodity has the tendency to replace the cold-rolled steel plate, the price is moderate, and it is loved by many customers. Mainly used for steel structure parts, highway bridge, ship, car manufacturing
