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.I-beamNorth Santa Cruz, China is a big steel country. The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.Al Basrat al Qadimah,At present, there is still a big gap in the production technology of C-section steel between China and foreign countries.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,North Santa CruzHow much is I-beam per kilogram, 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 axial movement is small,North Santa CruzHow much is 12Cr1MoVG alloy tube per ton, the working inclined plane is not required, the pass occupies a small length of the roll body, and more passes can be matched under the condition of a certain length of the roll body.

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.Classification by wall thicknessWhen 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,North Santa CruzHow much is a DN65 galvanized pipe, 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.Interpretation and observation,Generally, the process of pickling and passivation will be carried out for alloy pipes, but the alloy pipes after pickling and passivation are very easy to rust. Therefore, the way to find a solution to wiredrawing corrosion is 'grinding and polishing'. Due to grinding and polishing, there is no harm to carry out hot galvanizing in the middle and later stage.Difference and application description between H-beam and I-beam→ I-beam can be processed into T-beam, and honeycomb beam can be combined to form various section forms, which greatly meets the needs of engineering design and manufacturing.

According to the national standard of hot rolled H-section steel in China (GB / t-, wide flange and steel pile, whose codes are Hz, HK and Hu respectively. Narrow flange H-section steel is suitable for beams or compression bending members, while wide flange H-section steel and H-section steel piles are suitable for axial compression members or compression bending members. Compared with H-section steel, W, IX and iy are not as good as H-section steel under the premise of equal weight.market price,I-beam, also known as steel beam, is a long strip of steel with I-shaped section. I-beam is divided into ordinary I-beam and light I-beam. It is a section steel with I-type section shape. As long as the pipe material is high-strength alloy steel, including alloy steel pipes with temperature resistance, pressure resistance, wear resistance and low temperature resistance, the welding process shall be focused on preventing the tendency of martensite structure and cracks due to welding high-temperature operation. The general process requirements are that the welding rod shall be selected and baked as required and sent to the welder for use. The oil and water shall be removed before welding on both sides of the weld Rust and sundries shall be removed and cleaned. The welding line energy shall be as small as possible to minimize the swing during the welding process. The arrangement of the last weld shall have annealing effect on the heat affected zone as far as possible. Slow cooling after welding, etc.The specification of pass design I-beam is expressed in cm of waist width. For example, the waist width of No. I-beam is. The types of I-beam include hot-rolled ordinary I-beam, light I-beam and wide parallel leg I-beam (H-beam). The waist width of hot-rolled ordinary I-beam in China is ~, and the inclination of inner wall of leg is : The pass system of rolled I-beam includes direct pass system, cross pass system and mixed pass system. In addition, I-beam can also adopt special rolling method.North Santa CruzH-section steel belongs to high-efficiency and economic cutting profile (other cold-formed thin-wall section steel, profiled steel plate, etc.). Due to the reasonable section shape, they can make the steel give more play to its performance and improve the cutting capacity. Different from ordinary I-type, the flange of H-section steel is widened, and the inner and outer surfaces are usually parallel, so it is convenient to connect with other components with high-strength bolts. Its size composition is reasonable, series and models are complete, which is convenient for settingAfter isothermal quenching treatment the modified LNs steel of case hardening steel also has the surface compressive stress characteristics obtained by heat treatment.Mixed Scabs are distributed periodically, and the situation after casting and rolling is significant through edge flame peeling crack inspection or billet scratch flame removal.
