Q:What is hot rolling? What is called forging?
Forging is a method of processing wool embryos by plastic deformation. They are also classified as cold forging and hot forging
Q:What is the difference between a circle and round steel continuous casting
The first two density is not the same, the round billet continuous casting billet is molten steel into round billet crystallizer, after two cold water cooling, solidification formation, density is small; bar is formed by the billet or round billet rolled steel products, good density, better mechanical properties than the same size of billet. Second, round billet is the raw material for steel rolling, and the bar is the final product sold as steel.
Q:The difference between galvanized round bar and galvanized flat steel?
Galvanized round bar and galvanized flat steel are of different shapes and different uses.
Q:Will the theoretical weight of thread steel and round steel be the same?
The difference between such rebar and round bars with longitudinal ribs and transverse rib surface, usually with two longitudinal ribs and transverse ribs along the length direction of the uniform distribution.
Q:What are the differences between the products made of wrought round steel and hot rolled round steel and tested by mechanical testing after heat treatment?
Hot rolled round steel products made in forging round steel, this is because of forged steel ingot is as equivalent to the blooming state of the existing semi finished steel. Its structure, properties and impurity content are far below the quality level of hot rolled round steel.
Q:On the market, 8mm Round Bar is not 9 meters a root? How much does it weigh about 300 meters? How much does it cost?
Method of calculating reinforcement weight, unit length, weightD*d*0.00617= (6 in 7)For example, 8mm steel 8*8*0.00617=0.39488 take 0.395Round steel and rib are calculated the same wayRound bar 8 is rolled up, usually between 2~4 tonsYou'll have to straighten it up, straighten it up, and straighten it up
Q:What are the main differences between wrought round steel, hot rolled round steel and cold drawn round steel? Where are they used separately?
Cold drawn round steel (don't know, you mean can not cold dial round bar). But I understand by the cold dial round bar Also mainly used in hardware parts processing and production. Such as hinge shaft core or other surface and diameter requirements of production and processing occasions.
Q:Difference between forging and round steel
A forging is a process in which a metal is heated and shaped by plastic deformation or a desired compressive force is applied. This force is typically achieved by using a hammer or pressure. The casting process constructed a fine grain structure and improved the physical properties of the metal. In the practical use of parts, a correct design allows the particles to flow in the direction of the main pressure.
Q:Special steel bar steel products used to do what
Carbon tool steel is high carbon steel basically contains alloy elements, the carbon content in the range of 0.65% ~ 1.35%, the production of low cost, easy to obtain raw materials, good machinability, after treatment can obtain high hardness and high wear resistance, so it is widely used in steel, used to manufacture all kinds of cutting tools, mold, measuring.
Q:Could you tell me what is the difference between steel pipe and round steel?
Steel tube or conventional weapons indispensable materials, barrel, barrel to steel pipe manufacturing. The steel pipe can be divided into round tube and special-shaped pipe according to the cross sectional area and shape. Because of the condition of equal circumference, the circle surfaceThe product is the largest and uses round tubes to hold more fluids. In addition, the ring section is subjected to an average force when it is subjected to internal or external radial pressure, so most steel tubes are round tubes.
