Steel coil, also known as coil steel. The steel is hot-pressed and cold-pressed into rolls. In order to facilitate storage and transportation, it is convenient to carry out various processing (such as processing into steel plates, steel strips, etc.).
The Chinese name is steel coil, the foreign name is Steel Coil, also known as the method of coiling steel.
The steel plate is a flat steel that is cast with molten steel and pressed after cooling. It is flat, rectangular and can be directly rolled or cut from wide steel strips.
Formed coils are mainly hot-rolled coils and cold-rolled coils. Hot rolled coil is the processed product before the recrystallization of the steel billet. Cold rolled coil is the subsequent processing of hot rolled coil. The general weight of the steel coil is about 15-30T. my country's hot rolling production capacity has been continuously expanded. There are already dozens of hot rolling production lines, and some projects are about to start construction or put into production.
The sale of steel coils in coils is mainly aimed at large customers. Generally, users do not have uncoiler equipment or have limited consumption. Therefore, the subsequent processing of steel coils will be a promising industry. Of course, the larger steel mills currently have their own decoiling and leveling projects.
The steel plate is divided according to the thickness, the thin steel plate is less than 4 mm (the thinnest is 0.2 mm), the medium-thick steel plate is 4-60 mm, and the extra-thick steel plate is 60-115 mm.
Steel sheets are divided into hot-rolled and cold-rolled according to rolling.
The width of the thin plate is 500~1500 mm; the width of the thick sheet is 600~3000 mm. Sheets are classified according to steel types, including ordinary steel, high-quality steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel and industrial pure iron sheet, etc.; Enamel plate, bulletproof plate, etc. According to the surface coating, there are galvanized sheet, tin-plated sheet, lead-plated sheet, plastic composite steel plate, etc.
Steel plate use classification: (1) Bridge steel plate (2) Boiler steel plate (3) Shipbuilding steel plate (4) Armor steel plate (5) Automobile steel plate (6) Roof steel plate (7) Structural steel plate (8) Electrical steel plate (silicon steel sheet) (9) ) spring steel plate (10) heat-resistant steel plate (11) alloy steel plate (12) other
