Many people will mix strip steel and steel plate together, which can usually be distinguished from the following points. First of all, the thickness of the steel plate is much thicker, and the thinner the strip steel is required, the better. Secondly, in appearance, the steel strip can be crimped and the steel plate is too thick to bend, even if it is bent, it is difficult to recover, because it is easy to break if it is bent too much. Thirdly, the strength of A709 Gr 36 bridge steel plate, steel plate is higher than that of strip steel. The steel plate is suitable for construction engineering, while strip steel is only suitable for processing into hardware products.
Low carbon steel is a carbon steel with a carbon content of less than 0.25%. Low carbon steel A709 Gr 36 bridge steel plate is also called soft steel or mild steel because of its low strength and low hardness. Low carbon steel includes most common carbon structural steel and a part of high-quality carbon structural steel, most of which are used for engineering structural parts without heat treatment, and some A709 Gr 36 bridge steel plate are carburized and other heat treated for mechanical parts that require wear resistance.
"Adhere to green development, implement basic national policies to conserve resources and protect the environment, and take the goal of creating a resource-saving and environment-friendly iron and steel joint enterprise to promote the construction of ecological civilization.Strengthen the construction of core talents, further release the talents' innovative wisdom and innovation potential, and promote the efficient and high-quality development of enterprises. Adhere to the people-oriented principle, persist in relying on employees for development, share development results with employees, and build a harmonious enterprise."
After extrusion, the A709 Gr 36 bridge steel plate tube shall be removed for sizing. The sizing machine uses a cone-shaped bit to rotate into the steel embryo at high speed to drill holes to form steel pipes. The inner diameter of the steel pipe is determined by the outer diameter length of the drill bit of the sizing machine. After sizing, the steel pipe will enter the cooling tower and be cooled by water spray. After cooling, the steel pipe will be straightened. After straightening, the steel pipe is sent to the metal flaw detector (or hydraulic test) by the conveyor belt for internal flaw detection.
