Production Flow of High Quality Round Bar

The common processes are preheated forging quenching, dual refinement solution process, cooling quenching and isothermal quenching. We use heat treatment for dual refinement solution process. The main measures process is high temperature solution and refinement cycle. High temperature solution can improve the carbide morphology and particle size. The aim is to make the loop refinement ultrafine austenite grains.

Q:What is the difference between common wire and high-speed wire?
The universal wire and high speed wire are the wire rods (bars) of the rolling mechanism.High wire: refers to the use of high-speed torsion mill rolling wire rod. The rolling speed of 80-160 M / s, each weight (disc) in 1.8-2.5 tons, tolerance of high precision (up to 0.02mm), in the rolling process by adjusting the process parameters (especially in the cooling line) to ensure the different requirements for the product.
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:How to make the round welds on flat steel flat and qualified?
If it is full weld, for strong, don't groove. There must be no problem with the welding. If you hit the groove, it will deform. When welding, you should do spot welding and diagonal welding. I think you should be able to understand this, but I don't know what you are using for it,
Q:Are the bolts for the round bar or round steel?
If in some large-scale concrete component under the condition of some units to prevent run mode is used, the bar, the bar is the best quality, and the tensile strength is great, because the price advantage is not, it is generally not recommended to use the bar as a pull screw.
Q:How do you know the diameter and weight of a round bar?
The weight divided by the length is the bottom area of 2, Wu R - is the bottom area. The diameter is equal to 2R
Q:What is the difference between strip steel and round steel? Where are they mainly used?
Strip steel is a kind of narrow and long steel plate produced by various rolling mills to meet the needs of industrial production of various metal or mechanical products in different industrial sectors. Strip steel, also known as steel strip, is within 1300mm in width, and the length varies slightly according to the size of each roll. The strip is supplied in general, and has the advantages of high dimensional accuracy, good surface quality, easy processing and material saving. Same as steel plate, strip steel is divided into two kinds of ordinary strip steel and high quality strip steel according to the material used, and two kinds of hot-rolled strip steel and cold rolled strip steel according to processing method.Strip steel is widely used in the production of welded steel pipe, made of cold formed steel billet, manufacturing bicycle frame, rim, clamp, gasket, spring, saw blades, hardware and blades.
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:The diameter of 20 solid round steel bend into a circle, what machine bending?
Steel hoop benderConstruction: steel bending machine is suitable for bending stirrups, the bending angle can be adjusted arbitrarily, the structure is similar to the bending machine.Working principle: motor powered by a pair of wheels and two straight gear reducer, the eccentric disc rotates. The eccentric disc drives two connecting rods through an eccentric hinge, each connecting rod is hinged with a rack, so the rack moves reciprocally along the slideway. The rack also drives the gear to make the working disc reciprocate in a certain angle. The work disc has two axle holes, the central hole is inserted into the central shaft, and the other jack is arranged on the shaft. When the work disc is rotated, the central shaft and the forming shaft rotate together. The same principle of the steel bending machine can bend the steel bar into the required stirrups.
Q:Weight algorithm of round steel
Round bar is divided into three parts: hot rolling, forging and cold drawing. Standard Specification for hot rolled round steel is 5.5-250 mm. Where: 5.5-25 mm small round steel mostly straight bundles of supply, used for steel, bolts and various mechanical parts; greater than 25 mm round steel, seamless steel pipe is mainly used for the manufacture of mechanical parts of the tube, etc..
Q:Can the same grade steel instead of round bar be ok?
Physical and mechanical properties are different. Because of the different chemical composition and strength of reinforcing steel, they are different in physical and mechanical properties. The cold bending property of steel is good, can make the hook 180, screw steel can only make straight hook 90 degrees; steel weldability is good, with ordinary carbon steel electrode can be used to low alloy electrode; anti fatigue performance and toughness in steel bar is good.
