The working principle of flat steel finishing machine in I-beam production process is to pre level and finally level the cold flat steel with two groups of leveling wheel sets staggered up and down in the thickness direction; A pair of finishing wheels arranged relatively are used to extrude the width direction, so that the width is compressed to achieve the expected parameters, and the compression amount is adjustable; Straighten the width with staggered straightening wheels.The flange of H-beam is of equal thickness, including rolling section and combined section composed of three plates welded. All I-beams are rolled sections. Due to poor production technology, the inner edge of the flange has a slope of : The rolling of H-beam is different from that of ordinary I-beam. Only one set of horizontal rolls is used. Because its flange is wide and has no inclination (or the inclination is very small), a group of vertical rolls must be added for rolling at the same time. Therefore, its rolling process and equipment are more complex than ordinary rolling mills. The maximum height of rolled H-section steel that can be produced in China is mm, which exceeds the welded composite section.Stobsy,Go all the way along the Tiegang overpass to wharf Near the lower bridge mouth, the reporter saw that a pump truck with an arm of meters was standing under the bridge spraying cement on the bridge deck, and more than a dozen workers were nervously carrying out leveling work.Carburizing: carburizing is the process of penetrating carbon atoms into the surface layer of steel. It also makes the low-carbon steel workpiece have the surface layer of high-carbon steel, the part of the workpiece can maintain the toughness and plasticity of low-carbon steel.Tarkwa,Function of I-beam: where is I-beam mainly used?The high-temperature passivation treatment of alloy pipe is to obtain the passivation treatment film by heating in the heat treatment equipment. Before passivation treatment, the surface layer of parts must be removed to remove waste. At a higher temperature, the passivation treatment film can be obtained according to the transformation temperature and time. The hue of passivation treatment film can refer to the annealing color of alloy pipe, and the main parameters of ambient temperature and time of heat treatment process can be selected.Alloy tube is widely used in our daily life, simplify the production and manufacturing process and save raw materials and production and processing construction time, such as roller bearing ring throwing Nowadays,Stobsy25 galvanized pipe 6 meters, how much is it, seamless steel pipe has been widely used to produce hydraulic jack sleeve. Product description of galvanized pipeI-beam can be divided into four types according to shape: cold-formed equal edge I-beam, cold-formed unequal edge I-beam,d. All machines and equipment in a production line can connect with the software of the computer data collection system to complete the timely transmission of data information,StobsyGH4169 alloy pipe,StobsyHow much is 200 galvanized pipe per meter, and the performance parameters in the production process are monitored by the central control room.I-beam: national standard * what is the wall thickness of I-beamGenerally, there are many passivation methods for alloy tubes, the common ones are high temperature passivation or sodium cyanide passivation.

The system is mainly composed of control box, finishing roller pre leveling unit, finishing unit and straightening unit.Professional is king,When it is used for ground heating and hot spring transportation, it can meet the requirements of refrigeration and achieve the practical effect of less damage. It is applicable to water conservancy engineering, mining and other industries to meet the provisions of cold, cold and corrosion prevention. In addition, the chemical raw material transmission pipeline has a wide indoor space.Thin wall steel pipe, thick wall steel pipe.I-beam is widely used in buildings or other metal structures.Stobsy,I-beam, whether ordinary or light, can only be directly used for bending members or lattice members on its Web because of its large and narrow section size and large moment of inertia difference between the two main axes on the section. It is not suitable for axial compression members and flexural members perpendicular to the web plane, so its application range is very limited. I-beams are widely used in buildings and other metal structures.The shape of I-beam is similar to that of H-beam. What is the difference between them?Ways to obtain surface compressive stress characteristics of alloy tubes
