Classification and use of packaging steel strip
The steel plate is flat and rectangular, and can be directly rolled or cut from a wide steel strip. The steel strip refers to the steel strip delivered in coils, collectively called the plate steel.
Plate and strip steel can generally be divided into two types according to the thickness of the product; for steel strip, according to the product width, it can be divided into two types: narrow steel strip and wide steel strip. my country's GB/T 15574-1995 stipulates that the thickness of less than 3mm is called thin plate, the thickness of greater than 3mm is called thick plate; the width of steel belt is less than 600mm is called narrow steel belt, and the width of not less than 600mm is called wide steel belt. At present, the thinnest hot strip steel in my country can reach 0.8mm, the thickness can reach 25.4mm, and the widest can reach 2050mm.
Hot-rolled wide-band steel products are mainly supplied to cold rolling mills in the state of steel coils as raw materials. At the same time, they also directly sell hot-rolled steel coils and finished products to users and the market, namely flat steel coils, sub-coil steel coils, and longitudinal steel coils. Cut narrow strip steel coils, cross-cut steel plates, and pickled hot-rolled steel coils have been sold in recent years.
The hot rolled steel coils used as raw materials for cold rolling mills. The main steel grades are low carbon steel (including ultra-low carbon steel) and ordinary carbon structural steel. In addition, raw material steel coils such as oriented silicon steel, non-oriented silicon steel, and stainless steel thin strips for cold rolling mill production are also produced by hot-rolled wide strip steel rolling mills.
