1.What is Q235 carbon steel coil used for?
Q235 carbon steel coil from Chinese manufacturer is made from slab (mainly continuous casting billet), heated and made into strip by roughing mill and finishing mill. The hot strip from the last finishing mill is cooled to a set temperature by laminar flow and rolled into coils by the coiler. Q235 carbon steel coil is widely used in construction and engineering welding structure, used to manufacture steel bars or the construction of factory buildings, high voltage transmission towers, Bridges, vehicles, boilers, containers, etc., is also used for mechanical parts with lower performance requirements, Such as low stress rod, connecting rod, screw, nut, ring, bracket, bracket, etc. From the general engineering structure to the automobile, bridge, ship, boiler and pressure vessel manufacturing, have been widely used. Different uses, the material performance, surface quality and size of steel plate, shape accuracy and other requirements are also different. Therefore, it is necessary to understand the varieties, materials, characteristics and uses of coil products in order to achieve economic and reasonable use.
2.what is steel coil manufacturing process ?
The coil production process includes the following steps
P1: The steel coil material is unwound by the uncoiler and pressed repeatedly by the press roller to get the straightening steel strip;
P2: The straightening steel strip is placed in the pickling tank for soaking and pickling to obtain the pickling steel strip;
P3: Wash the pickling steel strip with water to obtain the washed steel strip;
P4: The washed steel strip is placed in the annealing furnace and annealed to obtain the annealed steel strip;
P5: Cut the annealed steel strip head and tail, use automatic welding machine for head and tail welding, and get the welded steel strip;
P6: The heated steel strip is obtained;
P7: Get the rolled steel strip;
P8: Steel strip coil is obtained;
P9: The production of steel coil can be completed, effectively improve rolling efficiency and quality, reduce cracking, cutting and trimming with edge cutting machine, to ensure the quality of steel coil, convenient and efficient production and processing, conducive to popularization and use.
