The laser cutting technology for material S620QL

Both the cross rolling method and the extrusion method must first heat the tube blank or ingot, and the steel tube produced is called hot rolling tube. Steel pipes produced by hot working can sometimes be cold worked as required. There are two methods of cold working: one is cold drawing, that is, drawing the material S620QL steel pipe through the drawing die to make the steel pipe gradually thin and elongate; the other is cold rolling, which is the method of applying the hot rolling mill invented by the menesmann brothers to cold working. The cold working of material S620QL seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.Steel plates for high-rise buildings have the properties of easy welding, earthquake resistance, and low-temperature impact resistance, and are mainly used in large-scale projects such as high-rise buildings, super-tall buildings, large-span stadiums, airports, exhibition centers, and steel structure workshops. Compared with ordinary Q235B / Q345B steel plates, these plates material S620QL for high-rise buildings have upper limits on yield strength and improved tensile strength, and have requirements for carbon equivalent and yield ratio indexes.It is a modern high-tech professional enterprise integrating scientific research, material S620QL production and sales. The company is mainly engaged in the manufacture, installation and commissioning of boiler and pressure vessel, chemical, metallurgical, petroleum and other equipment, as well as material S620QL process technology development, technology transfer and related technical consulting and technical services."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."
