Physical Properties
Special product specifications. The thickness is 8-50mm, width 150-625mm, length 5-15m, and the product specifications are closely spaced to meet the needs of users, and can be used instead of medium plate, without cutting, and can be directly welded.
The surface of the product is bright and clean. The process of high pressure water descaling is used for the second time.
The two sides are vertical and the corners are clear. The second pass of vertical rolling in fine rolling ensures good verticality of both sides, clear corners and good surface quality of the sides.
The scale of the product is precise, the three point difference and the same level difference are better than the standard of steel plate; the product is flat and straight, and the plate shape is good. Precision rolling adopts continuous rolling process, automatic live sleeve automatic control to ensure no steel stacking and no steel pulling, high dimensional accuracy of the product, tolerance range, three point difference, same grade difference, sickle bend and other parameters are better than the medium plate, and the plate straightness is good. Cold shear shear, high accuracy of length sizing.
Product material adopts national standard, same as steel plate. Quality and technical standards are organized and produced according to YB/T4212-2010 standard (Q345B/Q235B refer to GB/T1591-94, respectively.
Typical use
1. Hot-rolled flat steel is a long, potentially rolled steel with a rectangular cross-section for general use. Its specifications are expressed in millimeters of thickness*width. Flat steel can be finished steel, used for components, ladders, bridges and fences, etc. Flat steel can also be used as billets and slabs for welded steel and laminated sheet. (Material: Q215, Q235), implementation standard: GB704-1988 instead of GB704-83, this standard applies to the thickness of 3 ~ 60mm, width of 10 ~ 200mm, rectangular cross-section of general-purpose hot-rolled flat steel. Delivery status: Flat steel is delivered in straight bars. Measurement: Flat steel of fixed length and guys length is delivered by theoretical weight.
2. forged flat steel is forged long steel plate with a rectangular cross-section. Forging can not only get a certain shape and size of forgings, but also can significantly improve the cast steel organization, improve the density of steel; can change the distribution of fiber organization, remove anisotropy, improve the mechanical properties of the metal, so that the strength and toughness of steel are improved; and can be processed plasticity is lower in the high steel and high alloy steel. Forged flat steel is mainly high-quality alloy steel, mainly used for springs, tools and important mechanical parts. The specification of forged flat steel is expressed in mm of thickness*width, and the specification is 20mm*40mm~160mm*300mm. execution standard: GB/T16761-1
Main products
Section steel is one of the four major types of steel (plate, tube, type, wire). According to the shape of the section, the section steel is divided into simple section steel and complex section steel (section steel). The former refers to square steel, round steel, flat steel, angle steel, hexagonal steel, etc.; the latter refers to I-beam, channel steel, steel rail, window frame steel, bending steel, etc.
Square steel – square section steel, hot-rolled and cold-rolled; hot-rolled square steel side length 5-250mm; cold-drawn square steel side length 3-100mm.
Round steel – round section of steel, divided into hot-rolled, forged and cold-drawn three, hot-rolled round steel diameter 5-250mm, of which 5-9mm is commonly used as raw materials for drawing steel wire, called wire rod; as into the plate supply is also called hot-rolled coil. Forged round steel straight is thicker, used as a shaft billet. Cold-drawn round steel diameter 3-100mm, high dimensional accuracy.
Angle steel – divided into two kinds of equal and unequal angle steel. The specification of angle steel is expressed by the size of the side length and side thickness. Usually the specifications of angle steel produced are No. 2-20, i.e. the number of centimeters of side length. Such as No. 5 equilateral angle steel that refers to the side length of 5cm (50mm) angle steel. The same number of angles often have 2-7 different side thicknesses.
Flat steel weight calculation method
Flat steel: weight per meter = 0.00785 * thickness * side width
