→ under the same section load, the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.H-section steelWolfsburg,How to judge the quality of seamless pipe?Generally, there are many passivation methods for alloy tubes, the common ones are high temperature passivation or sodium cyanide passivation.Nice→ the two surfaces of the flange are parallel to each other, making it easy to connect, process and install. Cold extrusion. This kind of processing method is more purposeful. Before the preparation of steel processing and extrusion molding, when the extrusion molding is used for mm diameter pipe fittings, the investment of machinery and equipment is less, so the raw material consumption is also very small, and the technology is relatively perfect. Once the tube size is increased, the cold extrusion method must have large cargo capacity and high-power machinery and equipment. Therefore, the automatic control system will be upgraded.The flange of H-beam is of equal thickness,WolfsburgSuperalloy tube gh4586, 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),Wolfsburg304 seamless pipe wholesale, 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.

The specification of I-beam is expressed in cm of waist width. For example, the waist width of No. I-beam is cm. 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 ~ mm, expressed as No. ~ No., and the inclination of inner side wall of leg is : The pass system of rolled I-beam includes direct rolling pass system, cross rolling pass system and mixed pass system. In addition, I-beam can also adopt special rolling method. Welded steel mesh, a new form of reinforcement, is especially suitable for large-area concrete engineering.What is the stainless steel passivation of alloy pipe?Quality documents,In order to make the steel pipe workpiece have the required mechanical, physical and chemical properties, in addition to the reasonable selection of materials and forming processes, heat treatment process is often essential. Steel is the most widely used material in the mechanical industry. The microstructure of steel is complex and can be controlled by heat treatment. Therefore, aluminum, copper, titanium and their alloys can also change their mechanical, physical and chemical properties through heat treatment to obtain different service properties.It can withstand continuous moderate impact and can provide composite plates of various thicknessesI-beam is divided into ordinary I-beam and light I-beam. The specification of hot rolled ordinary I-beam is -#. The specification of hot-rolled flexible I-beam supplied through agreement between the supplier and the buyer is -#. I-beam is mainly used in building structure, vehicle manufacturing, small internal stress and no scratch on the surface. The alloy pipe produced and processed has higher coordination ability in the scope of size the thick steel plate has uniform deformation specification and model of diameter and wall thickness, especially in the production and manufacturing of steel structure design grade thick wall pipe, especially medium diameter small thick wall pipe, which has incomparable advantages of other processing technologies, and can meet a large number of customer regulations on the specification and model of alloy pipe.analysis,Because the section size of ordinary I-beam and light I-beam is relatively large and narrow, the moment of inertia of the two main shafts on the section is quite different,WolfsburgHow much is 65 welded pipe per meter, which limits its application range. I-beam shall be selected according to the requirements of design drawings. In the structural design, the use of I-beam should be reasonably selected according to the mechanical properties, chemical properties, weldability and structural size of I-beam. In order to ensure the welding quality of pipes, welders shall be trained, the welder should consider the operation skills. The pipe welding process may include several postures of overhead welding, vertical welding and overhead welding (when the pipe cannot rotate). The size of current should be selected to take into account the formation of vertical welding and overhead welding (some pipes are not very large, and the current cannot be adjusted in the middle of one formation). In the process, the stability and formation of arc should be controlled, It can swing properly, and the forming shall be well combined with the necessary swing.Nitriding: also known as nitriding, gas nitriding is widely used in the production of alloy steel pipe.Wolfsburg,Under the action of thermal stress, because the initial temperature of the surface layer is lower than that of the heart and the shrinkage is greater than that of the heart, the heart is pulled. At the end of cooling, because the final cooling volume shrinkage of the heart cannot be carried out freely, the surface layer is compressed and the heart is pulled. That is, under the action of thermal stress, the surface of the workpiece is finally compressed and the center is pulled. This phenomenon is affected by factors such as cooling rate, material composition and heat treatment process. The faster the cooling rate, the higher the carbon content and alloy composition, the greater the uneven plastic deformation caused by thermal stress during cooling, and the greater the final residual stress. On the other hand, due to the change of microstructure during heat treatment, i.e. the transformation from austenite to martensite, the increase of specific volume will be accompanied by the expansion of workpiece volume and each part of workpiece will undergo phase transformation successively, resulting in inconsistent volume growth and structural stress. The final result of the change of tissue stress is the tensile stress on the surface and the compressive stress in the center, which is just opposite to the thermal stress. The microstructure stress is related to the cooling rate, shape and chemical composition of the workpiece in the martensitic transformation zone.The finished product has smooth surface, low friction coefficient, flatness error + / - mm / m length, wear resistance and maximum temperature of ℃It is often asked that the shape of I-beam is similar to that of H-beam. What is the difference between them? Many people can&#;t explain it in detail. Here is a detailed answer for you: many people think that I-beam is a domestic name and H-beam is a foreign name. In fact, this cognition is wrong. H-beam and I-beam are different in shape!
