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. Miscellaneous scabShtep, It is the trend of the development of steel bar industry to take the road of steel bar welding mesh in steel bar construction. Small longitudinal crackBotshabelo,When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size.The 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.What are the uses of I-beam?

What is nitriding of alloy pipeWire sleeve: it is also a general carbon steel welded steel pipe. It is used in concrete and various structural power distribution projects. The commonly used nominal diameter is from -mm. The wall of wire sleeve is thin, and cold bending test is required.As shown in the name I-beam is an I-shaped section steel. The inner surface of the upper and lower flanges has an inclination, generally :, the section characteristics of I-beam in the two main planes are very different, and it is difficult to give full play to the strength characteristics in application. Although the thickened I-beam has also appeared in the I-beam market, the structure of the I-beam has determined its torsional performance.Application process,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.After determining the reasonable pickling agent and polishing solution,ShtepHow much is a meter of stainless steel welded pipe, it is very easy to carry out hot galvanizing for relevant alloy pipes. Use 'phosphating treatment' to degrease the pipes of electrolytic machine equipment, put them into the aqueous solution with zinc salt after pickling and passivation, connect the negative level of electrolytic machine equipment, put them into the cold-rolled steel plate in the direction corresponding to the pipes,ShtepHow many kilograms per meter of 80 welded pipe, and connect the switching power supply, If the current flows from the positive stage to the negative stage a layer of zinc is deposited in the pipe. 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 can only be used for beam, while H-beam can be used for load-bearing column of structure.Welcome to inquire,ShtepWill reinforced concrete rise or fall in 2021,GB No. I-beam is in height, in leg width and in waist thickness. According to the diameter of the pipe, which can be formed by welding two on one side. Through the steel ball test, it can ensure that the cross-sectional area passing capacity and weld formation meet the design requirements.Last week, the billet in North China market showed a slight rebound trend. The billet quotation in Tangshan, rose first and then stabilized in four trading days, with a strong wait-and-see atmosphere in the market. Affected by the almost stagnation of festival procurement, Tangshan billet fell by yuan during the Dragon Boat Festival holiday. On the first day after the festival, although the phase snail is still running at a low level, due to the small billet resources in the market, the steel mills unexpectedly rose, and the billet market rebounded. However, due to the continuous increase of capital pressure and the downturn in the transaction of downstream finished materials, the steel plant has always maintained a cautious wait-and-see attitude to maintain stability.Shtep,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.Generally, the process of pickling and passivation will be carried out for alloy pipes, but the alloy pipes after pickling and passivation are very easy to rust. Therefore, the way to find a solution to wiredrawing corrosion is 'grinding and polishing'. Due to grinding and polishing, there is no harm to carry out hot galvanizing in the middle and later stage.I-beam is mainly divided into ordinary I-beam, light I-beam and wide flange I-beam. According to the height ratio of flange to web, it is divided into wide medium and narrow flange I-beams. The specifications of the first two are -, that is, the corresponding height is -. At the same height, the light I-beam has narrow flange, thin web and light weight. Wide flange I-beam, also known as H-beam, is characterized by two parallel legs and no inclination on the inner side of the legs. It belongs to economic section steel and is rolled on four high universal mill, so it is also called 'universal I-beam'. Ordinary I-beam and light I-beam have formed national standards.
