PPGI And GI Steel Coil
Jul 24, 2017

              The forming rolls are mainly hot rolled coils and cold rolled rolls. Hot rolled coils are processed products before billet recrystallization. Cold rolled coils are the follow-up process of hot rolled coils. The general weight of steel coils is 15-30t. This year, China's hot rolling production capacity has been expanding, there are dozens of hot rolling production lines, there are some projects will be opened or put into production.PPGI And GI Steel Coil

              Coil sold mainly for large customers, the general users do not have the equipment or the amount of limited. Therefore, the subsequent processing of steel coils will be a promising industry. Of course, the larger steel mills now have their own unwinding and leveling projects.PPGI And GI Steel Coil

              The hot rolled plate is made of strip (mainly continuous casting slab), which is produced by Roughing Mill Group and finishing mill after heating. The hot strip from the finishing mill is cooled to the setting temperature through laminar flow, and the coiling machine rolls gang with the coil. After cooling the steel strip, according to the different needs of users, through different finishing line (leveling, straightening, cutting or slitting, inspection, weighing, packaging and marking, etc.) processing to become steel plate, flat roll and slitting steel strip products. Because hot tandem rolled steel plate products have high strength, good toughness, easy to process molding and good weldability and other excellent performance, it is widely used in shipbuilding, automobiles, bridges, construction, machinery, pressure vessels and other manufacturing industries.PPGI And GI Steel Coil
