Usage and Applications of Chinese Standard Round Bar

1. Chinese standard steel bar is often used where large amounts of steel need to be formed, for example as structural steel.

2. And we can use this kind of product on the performance of the mechanical parts if the demand is not very high.

3. Steel round bar is used in construction and a large number of architectural and engineering structures.


Packaging & Delivery of Chinese Standard Round Bar

Packaging Detail: All goods are packed in bundle with steel strips and shipped by break bulk vessel or container (depend on target market and different ports)

Delivery Detail: 45 days

Trade terms: FOB, CFR, CIF

MOQ: 25 tons per specification; we can negotiate the quantity if the specification is normal or we have stock of one specification.

Weight: The price invoicing on theoretical weight basis or actual weight basis depends on customer’s request.

Shipment: The shipment of bulk break or container is depends on customer’s request and the situation of the port of destination.

Documents given: Full set of original clean on board bill of lading; Original signed commercial invoice; Original packing list; Policy of insurance; Certificate of origin and what the target market needs.


Production Flow of Chinese Standard Round Bar

1. 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.

2. Material prepare (billet) — heat up — rough rolling — precision rolling — cooling — packing — storage and transportation


Characteristics of Chinese Standard Round Bar

1. The steel in which the main interstitial alloying constituent is carbon in the range of 0.12–2.0%.

2. As the carbon percentage content rises, steel has the ability to become harder and stronger through heat treating; however it becomes less ductile.

3. Quality should be in conformity with the specification of the manufacturer. Quantity and packing conditions should be in conformity with the term in the contract.

4. Regardless of the heat treatment, higher carbon content reduces weld ability. In carbon steels, the higher carbon content lowers the melting point.

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?
8 there is no regular reinforced steel bars are straight, round, there is straight, as you said 9 M 1, but that's rolling, if their home, can also, engineering is prohibited
Q:The diameter of 20 solid round steel bend into a circle, what machine bending?
Worm and worm type steel bar benderStructure: worm and worm type steel bending machine, mainly each family, motor, transmission system, work mechanism (work disk, insert seat, gripper, shaft, etc.) and control system. A walking wheel is arranged under the frame for easy movement.Working principle: the power of the motor is rotated by the V belt pulley, the two straight gear and the worm gear rod, and then drives the working disk to rotate. The working disk usually has 9 shafts, the center hole is used to insert the central shaft, and the 8 hole seats around each have 6 holes, which are used to insert the retaining shaft. In order to move the reinforcing steel bar, two times of each work table is also provided with a feeding roller. When working, according to the bending shape of the steel bar, the square of the reinforcing steel bar is arranged between the central axis of the work disc and the corresponding forming shaft, and the inner side of the iron block is blocked. When the working disc is rotated, one end of the reinforcing bar is prevented from rotating by the iron blocking shaft, the central shaft position is fixed, and the forming shaft is rotated in an arc direction around the central shaft, and the reinforcing bar is bent.As a result of the specification, the bending diameter of the steel bar shall be no less than 2.5 times of the diameter of the steel bar when it is taken as a 180 degree bending hook. Therefore, the center shaft is also made into 16~100mm in 9 different specifications to meet the requirements of bending different diameter steel bars.
Q:Requirements for groove welding of grade 22mm round steel and manual arc welding
If not on the lathe, in the groove on the round bar with gouging or cutting gun, docking form X type double sided bilateral docking, blunt edge 2mm root gap 2mm welding, welding side sincere one or two seam, flip the workpiece on the other side of a full weld groove, flip weld residual,
Q:Are steel and round steel the same thing?
Round steel is a solid strip of steel whose cross section is round. Its specifications are expressed in diameter, in units of millimeters (mm), such as "50mm", which means a diameter of 50 millimeters of round steel.
Q:Will the theoretical weight of thread steel and round steel be the same?
The theoretical weight of threaded steel and round steel is the same. The middle part of the steel bar size ratio is small, the design time actually unit weight are the same, just screw steel crescent and transverse ribs prominent, resulting in heavy steel should be better than the illusion of formula is 0.00617 multiplied by the square of the diameter / m.
Q:What are the main differences between wrought round steel, hot rolled round steel and cold drawn round steel? Where are they used separately?
The main differences are in mechanical properties. I don't know very well how to make round steel, I can't compare it. Forged round steel is expected to be used in the processing of some special performance requirements.
Q:What's the difference between a round tube and a round tube?
Round steel is generally refers to steel, the surface is not threaded, different from round steel pipe, round tube is round tube.
Q:Is round steel bar round steel?
NoRound steel bars refer to hot rolled round steel bars for reinforced concrete. Round bars include high-quality carbon structural steel, round steel, ordinary carbon structural steel round bars, steel bars for prestressed concrete, etc.. Although the shape is round, but the material is different, so steel and round bar is two yards.
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?
In comparison, the general longitudinal performance of hot rolled round bar is better than that of transverse or tangential direction, and the difference between the two values is obvious. The banded structure is more obvious in the longitudinal microstructure, and the deformation of non-metallic plastic inclusions is more obvious
Q:Is there any technique for welding round steel?
Welding skills:2.1, to determine the best welding position, the group of good welding flat, easy to rotate welding, the weld pool is always in flat position, note the rod angle at 70 degrees.2.2, the welding workpiece in continuous continuous rotation, to control the size of the weld pool at the end of each lap weld slag, cleaned, and then welding together, the thickness of each layer is about 2mm, until the full fill slope has so far.
