I-beam, also known as steel 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.I-beam can be divided into four types according to shape: cold-formed equal edge I-beam, cold-formed unequal edge I-beam,ProsekHow much will I-beam cost per ton in 2021,ProsekQ345B longitudinal welded pipe factory, cold-formed inner crimping I-beam and cold-formed outer crimping I-beam.Prosek,Classification by production methodI-beam is a kind of economical section steel with better section mechanical properties. Its characteristics are as follows:Osasco,I-beam is an economic section high-efficiency profile with more optimized section area distribution and more reasonable strength weight ratio. It is named because its section is the same as the English letter 'H'. Mixed pass system. According to the characteristics of rolling mills and products, in order to give full play to the advantages of their respective systems and overcome their disadvantages, mixed pass system is often adopted, that is, the combination of more than two systems. For example, straight leg cross rolling pass system is adopted for finished hole and front hole of finished product, and bent leg cross rolling system is adopted for other passes; or direct rolling system is adopted for rough rolling hole and straight rolling system is adopted for the last ~ finish rolling holes Leg oblique tie hole, etc.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, 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.

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.Recently, the price of zinc has been falling continuously. The key reason lies in the soft skin of galvanized pipe consumption and the slow start of production and marketing rate of manufacturing industries in the middle and lower reaches after the Spring Festival. The disadvantage of zinc price has long been far beyond the level of cyclical factors. The main performance of no prosperity in the hot season is whether the market situation in the off peak season will become a more worried problem in the galvanized pipe sales market.When we carry out different projects, we must use different raw materials, which can ensure the quality of the project. In many kinds of data, alloy pipe is widely used. In many projects we will apply it, so it is very popular in the field. When people carry out the construction of alloy pipe project, there are many things that must be paid special attention to. Let&#;s take you to know:Information recommendation,Patented manufacturing process of I-beam: I-beam has become a new industrial standard for wear-resistant materialsI-beam, also known as steel 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.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.

C - section steel is reliable and stable in stress, can be accurately positioned, and is resistant to impact and vibration Moreover,Prosek16Mn alloy pipe, it has good versatility and combination, and has a variety of C-section steel and size selection to ensure its flexibilitysafety requirements ,Last week the billet in North China market showed a slight rebound trend. The billet quotation in Tangshan, the leading city, rose first and then stabilized in four trading days, 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 temperature difference will be formed, resulting in uneven volume expansion and contraction resulting in stress, the starting temperature of the surface layer is lower than that of the core layer namely thermal stress. Under the action of thermal stress, and the shrinkage is greater than that of the core layer, making the core layer stretch. At the end of cooling, the surface layer is compressed and the core is stretched because the cooling volume contraction of the core cannot be carried out freely. That is, under the action of thermal stress, the surface of the workpiece is compressed and the core is pulled.Precision cold rolling of small and medium-sized bearing sleeves with alloy tubes can greatly improve material utilization, bearing performance and service life. This paper systematically introduces the development of high quality cold drawn bearing steel pipe and its application in bearing. Precision cold rolling of small and medium-sized bearing sleeves with bearing steel pipes can greatly improve material utilization, bearing performance and service life. This paper systematically introduces the service life of high quality cold drawn bearings.Prosek,Plan scheme : high carbon steel with carbon content exceeding .% and alloy pipe with chromium content not less than %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!I-beam can be divided into four types according to shape: cold-formed equal edge I-beam, cold-formed unequal edge I-beam, cold-formed inner crimping I-beam and cold-formed outer crimping I-beam.
