GB No. I-beam is in height, cold rolling by three high limited mandrel mill and cold rolling by fluctuating mandrel mill. In this way cold rolling by few station mandrel mill, the advantages of high efficiency, low metal material consumption, excellent product quality and excellent automatic control system are more and more widely used. The competitive advantage of the latter one is low cost and short whole process. It is suitable for the processing and manufacturing of CrMoG alloy pipes with large quantities, small types, multi specifications and high precision. Therefore, it is widely usedMogilev,Thanks to a zinc tube, stand in the formation and development of painful microorganisms.Application scope of alloy pipeKitwe,It is a potential rolled strip steel with rectangular section for general purpose. It is very common on construction sites. Its specifications are expressed in thickness and width. At present, most of the flat steel on the market are finished steel,Mogilev15CrMo seamless alloy pipe, which can be used ready-made for components, ladders, bridges and fences. Flat steel can also be used as blank for welding rigid steel and slab for laminated thin plate.It can withstand continuous moderate impact and can provide composite plates of various thicknessesDetermined by the shape, the section modulus, moment of inertia and corresponding strength of I-beam are obviously better than those of ordinary I-beam with the same single weight. When used in metal structures with different requirements, it shows its superior performance in bearing bending moment, pressure load and eccentric load. Compared with ordinary I-beam, it can greatly improve the bearing capacity and save metal by % ~ %.

The general alloy pipe with improved performance is variable and has high application value. The alloy pipe contains more Cr and is heat resistant Low temperature resistance Corrosion resistance. There is no aluminum alloy in plain carbon seamless steel pipe, not very little aluminum alloy, and the alloy pipe is used in crude oil Aerospace Chemical plant Power engineering heating furnace. Because the physical properties of alloy tubes are easy to change and adjust.The use of welded steel mesh in China is still in its infancy. At present, the use of welded steel mesh in China accounts for less than one of the total amount of steel reinforcement. In the early s, steel welded mesh was listed as a key implementation project by the science and Technology Commission and the Ministry of construction, and specifications and procedures were formulated.According to the theory of steel structure the I-beam flange should be stressed, that is, the I-beam should be standing rather than lying down.Design brand,Mixed Scabs are distributed periodically, the surface of alloy pipe shall be clear of oil stains, pickled and passivated. Passivation treatment can be carried out only after the surface is cleaned, and the workpiece of alloy pipe products can be infiltrated into aqueous solution. The passivation treatment of the alloy tube in sodium cyanide transforms the surface layer into a very thin passivation treatment film,MogilevHow much is an 18cm I-beam, which determines that the color of the surface layer has no change before and after passivation treatment, and the reproducibility of the solution is good.

Mixed Scabs are distributed periodically,Mogilev15CrMoG seamless pipe factory, and the situation after casting and rolling is significant through edge flame peeling crack inspection or billet scratch flame removal.The cheapest,The utility model has the advantages that the axial force of the roll is small, the axial movement is small, 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.The second is the control of welding materials to ensure that the welding materials purchased are from formal channels, with quality assurance certificate and certificate, which meet the process requirements; The recovery of welding rod head shall be strictly controlled to ensure the flow direction and dosage; Welding materials shall be baked in strict accordance with the process, and the amount of one-time distribution shall not exceed half a day.With the development of steel structure buildings, only I-beam is not enough, that is, thickened I-beam, which is easy to lose stability for load-bearing columns.Mogilev,I-beam has the dual properties of high hardness and toughness materials. Compared with other engineering wear-resistant materials in China, such as various alloy steel plates, cast wear-resistant plates, rubber, polyurethane, etc., it has irreplaceable comprehensive excellent properties.Patented manufacturing process of I-beam: I-beam has become a new industrial standard for wear-resistant materials→ 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.
