Special rolling method. When it is difficult to roll the required I-beam by the usual rolling method for some reason, the special rolling method can be used to make full use of the skills of uneven deformation and pass design. For example, when the billet section is narrow and wide I-beam is required to be rolled, the wave rolling method can be used; for example, when the billet is wide and small I-beam is required to be rolled, the negative rolling method can be used Spread rolling, etc.I-beam is an economic section high-efficiency profile with more optimized section area distribution and more reasonable strength weight ratio. It is named because its section is the same as the English letter 'H'.FarnipoGalvanized pipe cleaning, east-west derusting, pickling and shot blastingMain uses: as a finished material, flat steel can be used to make hoop iron, tools and mechanical parts, and used as building frame structural parts and escalators in buildings. Flat steel is divided into two types according to its shape: plane spring flat steel and single-sided double groove spring flat steel. Hot rolled spring flat steel is mainly used to manufacture leaf springs for automobiles, tractors, railway transportation and other machinery.Amagasaki,When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size.However, what we need to do now is to improve the production technology level of China&#;s production process of C-section steel, and step up the formulation of relevant industry standards and inspection standards. C-section steel manufacturers should keep close contact with truck manufacturers and communicate more. In this way, it is more conducive for C-section steel manufacturers to produce C-section steel products suitable for truck industry. Frame line crack

The shape of I-beam is similar to that of H-beam. What is the difference between them?From the comparison of the monthly summary apparent consumption data information of galvanized pipe and the real estate sales data information from to this year, they show the consistency of height width ratio, which not only shows a positive correlation in the overall new trend, but also significantly conforms to the fluctuation direction of the monthly development trend.Whether I-section steel is ordinary or light, due to the relatively high and narrow section size there is a large difference in the moment of inertia between the two main sleeves of the section. Therefore, which makes it very limited in the scope of application.production costs it can only be directly used for members bent in the plane of their web or form lattice stress members. It is not suitable for axial compression members or members with bending perpendicular to the web plane,Last week, the billet in North China market showed a slight rebound trend. The billet quotation in Tangshan, the leading city, rose first and then stabilized in four trading days, with a strong wait-and-see atmosphere in the market. Affected by the almost stagnation of festival procurement, Tangshan billet fell by yuan during the Dragon Boat Festival holiday. On the first day after the festival, although the phase snail is still running at a low level, due to the small billet resources in the market, the steel mills unexpectedly rose, and the billet market rebounded. However, due to the continuous increase of capital pressure and the downturn in the transaction of downstream finished materials, the steel plant has always maintained a cautious wait-and-see attitude to maintain stability.Passivation treatment operation of alloy pipeAlloy pipe is a kind of seamless steel pipe. Alloy pipe is divided into structural seamless pipe and high-pressure heat-resistant alloy pipe. It is mainly different from the production standard and industry of alloy pipe. Annealing and tempering of alloy pipe changes its mechanical properties. Meet the required processing conditions. Its performance is higher than that of ordinary seamless steel pipe, its utilization value is higher, the chemical composition of alloy pipe contains more Cr,FarnipoHow much is spiral welded pipe,FarnipoHow much is 20 galvanized pipe per meter, and its performance of high temperature resistance, low temperature resistance and corrosion resistance. Ordinary carbon seamless tubes do not contain alloy components or have few alloy components. Alloy tubes are widely used in petroleum, aerospace, chemical industry, boiler and other industries because the mechanical properties of alloy tubes change and are easy to adjust.

The section of I-beam has good straight pressure and tensile resistance, but the section size cannot resist torsion because the wing plate is too narrow. On the contrary, H steel has its own advantages and disadvantages.Let's see,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,Farnipo6. How much is a ton of galvanized pipe, and there shall be no staggered joint during assembly. Electric welding positioning is generally spot welding. After inspection and straightening, the free conversion method shall be used for welding as far as possible.Nitriding: also known as nitriding, it is the process of penetrating nitrogen atoms into the surface layer of steel. At present,Plan option : Martensitic chromium alloy pipe, vehicle manufacturing, other industrial structures and fixed panels and cabinets. I-beam is often used together with I-beam.
