and the power is large,GuazarHow much is I-beam per meter, generally about KW, which is similar to the plate shearing and bending machine. The general control process is complex,GuazarHow much is 120 I-beam per meter, and PLC control is mostly used.Pass designGuazar,The allowable deviation of vertical installation of galvanized pipe is mm per meter, and the allowable deviation above m is no more than mm. The allowable deviation of horizontally installed pipes is mm per meter.Alloy pipes can be used for heating (cooling) projects.Skhirat, Judged as failing. The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge. 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 widely used in buildings or other metal structures. Carbon: the higher the carbon content, the higher the hardness of steel, but the worse its plasticity and toughnessa. In the forming process, the thick steel plate has uniform deformation, small internal stress and no scratch on the surface. The alloy pipe produced and processed has higher coordination ability in the scope of size, 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.whereWhat is the purpose of flat steelI-beam is a kind of economical section steel with better section mechanical properties. Its characteristics are as follows: 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, and the waist is parallel to the roll axis.

At present there is still a big gap in the production technology of C-section steel between China and foreign countries.discount, and honeycomb beam can be combined to form various section forms, which greatly meets the needs of engineering design and manufacturing.Guazar and honeycomb beam can be combined to form various section forms, Hot hole breaking cold rolling method. This method is dominated by expansion and expands vertical sliding and skew rolling. The former one is mainly cold rolling by relatively limited mandrel mill, cold rolling by few station mandrel mill, cold rolling by three high limited mandrel mill and cold rolling by fluctuating mandrel mill. In this way, 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 usedDry processing technology: after passivation treatment, parts shall be dried with air compression or hot gas, or drying treatment or air drying can be selected.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 ~, expressed as No. ~ No., 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.
