A flat steel rolled from a smooth roll. A steel plate supplied in a flat form; According to the different rolling temperature, it is divided into hot rolling and cold rolling. Hot rolled steel plate and steel strip are rolled in hot state of ingot or slab. Cold rolled steel plate and steel strip are made of hot rolled steel plate and steel strip, and then rolled in room temperature. Steel plate and steel strip, with the use of the plate with the requirements and different uses. At present, the steel plate and strip of the building is mainly the ordinary carbon steel.Steel Plate
Hot rolled steel plate is divided into thick plate (thickness is greater than 4 mm) and sheet (thickness 0.35~4 mm) Two; cold rolled steel plate (thickness 0. $number mm). It is customary to separate hot-rolled thick plates according to the thickness of the plate (thickness 4~25 mm), thick plate (thickness 25~60 mm) and special thick plate (thickness greater than 60 mm) three kinds. The maximum length of hot rolled steel plate is: Medium plate 12 meters, thin plate 4 meters, the maximum length of cold-rolled steel plate is 3.5 meters. The yield strength of steel plate is also grouped by thickness, and the yield strength decreases gradually with the increase of thickness.Steel Plate
Steel and steel strip is a general-purpose steel, the application is very extensive, thick plate is used for building, bridge, shipbuilding, container, pipeline, oil production platform and so on, the thin plate is mostly used as the roof and wall surface enclosure structure, or as the raw material of the coating steel plate, such as used for making profiled steel plate, Li iron sheet, etc. Welding pipe and construction hardware materials. The low alloy steel plate has the advantages of high strength, reduced structure weight and saving steel, and has been used more and more in China recently.Steel Plate
Some heavy-duty structures, large-span bridges, high-pressure vessels used in steel plate, generally used a variety of LOW-ALLOY steel plate, which is commonly used in 16 manganese, 15 manganese vanadium, etc. (including the corresponding bridge steel, container steel and boiler steel).Steel Plate
