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. Small longitudinal crackZabrzeh,Galvanized pipe has excellent corrosion resistance. Compared with traditional steel its application life is longer. Secondly, it will not lead to the collapse of building structure in a short time. In addition, this kind of pipe also has a practical advantage, that is, it is more convenient and lighter when carrying out the construction and installation. The operators save time and labor when carrying out the construction, it is not difficult to understand why the galvanized pipe is so favored by various construction units.At present, there is still a big gap in the production technology of C-section steel between China and foreign countries.Modena,According to the national standard of hot rolled H-section steel in China (GB / t-, H-section steel is divided into narrow flange, wide flange and steel pile, whose codes are Hz, 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,ZabrzehHow much is welded pipe 219, W, IX and iy are not as good as H-section steel under the premise of equal weight.The production process can be summarized as follows: pre leveling → finishing → straightening → post leveling. Flat steel / A / B steel with width of -, thickness of -, and the waist is parallel to the roll axis.

In order to make the welded pipe have the required mechanical or it can be used as blank for welded pipe and thin slab for laminated thin plate. Direct rolling pass system. The direct rolling pass system refers to the pass system in which the two open legs of the I-beam pass are on the same side of the roll axis at the same time, physical and chemical properties in addition to the reasonable selection of materials and forming process, heat treatment process is often necessary. In addition, the mechanical, physical and chemical properties of aluminum, copper, magnesium, titanium and their alloys can be changed by heat treatment to obtain different service properties. Silicon; it can improve the hardness of steel, but the plasticity and toughness decrease. Electrical steel contains a certain amount of silicon, which can improve the soft magnetic propertiesAlloy pipe is a spiral seam seamless steel pipe, which is made of hot-rolled strip steel coil, often processed by warm extrusion and welded by automatic double wire double side arc welding process. The alloy pipe sends the hot-rolled strip steel to the welded pipe unit, and the hot-rolled strip steel is extruded through multiple passes. The hot-rolled strip steel is rolled slowly to produce annular pipe material with open mouth gap. Adjust the reduction amount of the extrusion roll to control the welding gap at ~ mm and make both sides of the weld flush.Affordable price,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.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.Greatly reduce the environmental pollution caused by abrasion, damage and blanking, and increase the labor cost of material cleaning

→ the two surfaces of the flange are parallel to each other, making it easy to connect, process and install.Affordable price,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,ZabrzehAlloy pipe gh2747, 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. Application of galvanized pipeGreatly reduce the environmental pollution caused by abrasion, damage and blanking, and increase the labor cost of material cleaningZabrzeh, H-section steel is an economic section steel with better mechanical properties than I-section steel. It is named because its section shape is the same as the English letter 'H'. The flange of hot rolled H-beam is wider than that of I-beam, with large lateral stiffness and strong bending resistance. Under the same specification, H-beam is lighter than I-beam.Aiming at the connective tissue and texture produced in stainless steel plate Position and other crystal defects are generally removed by heat treatment processes such as quenching or quenching. The effect of quenching is to optimize the crystal eliminate structural defects, reduce strength, improve plastic deformation, and also conducive to cold drawing. In the production and manufacture of cold drawn alloy pipe, quenching machinery and equipment cannot be lacked. Therefore, the formulation of appropriate annealing process is a necessary condition to ensure that the alloy pipe mechanism meets the standard and the commodity does not crack. If the manufacturer in order to better one sidedness, reduce the product cost and reduce the quenching process, it will eventually lead to bad harm to the product quality.The key purpose of grinding and polishing alloy pipe is to moisten the surface, and the relevant limit accuracy or appearance change is not easy to change.
