I-beam is a long strip steel with groove section, which belongs to carbon structural steel for construction and machinery. It is a section steel with complex section, and its section shape is groove shape. China&#;s imports of I-beams are greater than its exports. The main producing areas are Tangshan Iron and steel, Baotou Iron and steel, Shangang, Maanshan Iron and steel, Xuanhua Iron and steel, Japan iron and steel, etc.The utility model has the advantages that the axial force of the roll is small, the axial movement is small, the working inclined plane is not required, the pass occupies a small length of the roll body, and more passes can be matched under the condition of a certain length of the roll body.Sallow, Spiral seam submerged arc welded steel pipe for general low-pressure fluid transportation (SY / t- is a submerged arc welded steel pipe for general low-pressure fluid transportation such as water, gas, air and steam, which is made of hot-rolled steel strip coil as pipe blank, often warm spiral forming and double-sided active submerged arc welding or single-sided welding. Frame line crackLabe,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.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.With the development of steel structure buildings, only I-beam is not enough, that is, thickened I-beam which is easy to lose stability for load-bearing columns.

Cross rolling pass system. This pass system refers to that the two open legs of the I-beam pass are not on the same side of the waist at the same time, when the billet section is narrow and wide I-beam is required to be rolled 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 is wide and small I-beam is required to be rolled,SallowCold drawn welded pipe manufacturer, the negative rolling method can be used Spread rolling etc.market,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. Frame line crackThe specification of pass design I-beam is expressed in cm of waist width. For example,SallowQuotation of No. 10 I-beam, 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 ~,SallowHow much is 6 meters of one inch galvanized pipe, 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.

Stages needing attention in the production and manufacture of alloy tubestechnological innovation,I-beam is widely used in buildings or other metal structures. Because the combination is strong, 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.Sallow,Alloy pipes are widely used in building materials, and the test standards of alloy pipes are also different. Alloy pipe has high hardness and can be used at many levels, most of which is prestressed reinforcement. Where plastic deformation is not specified but compressive strength is specified, such stainless steel plate can be applied.At the same height, light I-beam has narrower legs, thinner waist and lighter weight than ordinary I-beam. No. - is large I-beam, and No. - is medium I-beam. Imported I-beam shall be marked with actual specifications, dimensions and relevant standards.What are the requirements for alloy pipe construction accessories
