The working principle of flat steel finishing machine in I-beam production process is to pre level and finally level the cold flat steel with two groups of leveling wheel sets staggered up and down in the thickness direction; A pair of finishing wheels arranged relatively are used to extrude the width direction, so that the width is compressed to achieve the expected parameters, and the compression amount is adjustable; Straighten the width with staggered straightening wheels.Because alloy pipe is a very unique pipe fitting, we must use appropriate methods to carry out installation in the case of installation, so as to ensure the performance index of the data. Generally, when installing alloy pipes, we will use some flanges and elbows to fix them, so as to ensure that the raw materials can be fixed very well. Therefore, when we carry out use, we must ensure the quality of flanges and elbows, . the straight length of the hook of the surface mesh reinforcement at the grid support shall not be less than mm, and the bending diameter shall not be less than D (D is the reinforcement diameter).Application characteristics of I-beam:Ellinikón AirportWhat should we pay attention to in the production of alloy pipeThe import and export order of I-beam is generally based on the specifications required in use after determining the corresponding carbon structure steel (or low alloy steel) steel grade. Except for the specification number, I-beam has no specific composition and performance series.So why is the alloy pipe easy to rust after being pickled and passivated by the software?
I-beam: national standard * what is the wall thickness of I-beamThe two ends of the steel produced by the seamless pipe manufacturer shall be cut into right angles, and the burrs on the surface shall be removed, which is the raw material used by the seamless pipe manufacturer. The embryo prototube embryo needs to be cut by a cutting machine to form an embryo material with a length of about one meter, which is sent to the furnace for heating through the conveyor belt. The billet is sent to the furnace. After internal heating, the temperature is about degrees, and the fuel used is often ethyne. Temperature control in the furnace is a very key factor.→ compared with the concrete structure, the I-steel structure can increase the service area by %, reduce the self weight of the structure by % - %,BlumenoHow much is muhdpe alloy tube, and reduce the structural design internal force.Sales Department,C-section steel has uniform zinc layer,BlumenoIncoloy800H alloy pipe, smooth surface, strong adhesion, no zinc scar no zinc leakage and high dimensional accuracy. All surfaces are wrapped by zinc layer, and the zinc content on the surface is usually -g /? It has long service life, corrosion resistance and durability. It is a kind of stronger protection.Dry processing technology: after passivation treatment, parts shall be dried with air compression or hot gas, or drying treatment or air drying can be selected.I-beam, also known as universal 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.
Some applications of I-beam:Customer first,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. Phosphorus: it can significantly reduce the plasticity and toughness of steel, especially at low temperature. This phenomenon is called cold brittleness. In high-quality steel, sulfur and phosphorus should be strictly controlled. On the other hand, low carbon steel contains high sulfur and phosphorus, which can make it easy to cut,BlumenoHow many inches is the 180 welded pipe, which is beneficial to improve the machinability of steela. In the forming process, 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.BlumenoDehydrogenation solution: the alloy pipe shall be dehydrogenated after passivation treatment to avoid alkali embrittlementThe 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.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.
