Production Flow of Steel Round Bar Products

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

 

Characteristics of Steel Round Bar Products

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

4. 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.

 FAQ:

Q1: What makes stainless steel stainless?

A1: Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material.

Q2: Can stainless steel rust?

A2: Stainless does not "rust" as you think of regular steel rusting with a red oxide on the surface that flakes off. If you see red rust it is probably due to some iron particles that have contaminated the surface of the stainless steel and it is these iron particles that are rusting. Look at the source of the rusting and see if you can remove it from the surface.

Q:What is the tensile strength of round steel bars of diameter 28?
The tensile strength of round steel bars of diameter 28 is 27079.36~33849.2 kg. It is explained as follows: the material of rebar is generally Q235-A carbon structural steel, its yield strength is 235 MPa, tensile strength is 441~550 MPa, and it is 44~55 kg / mm2. The cross-sectional area of 28 mm in diameter is about 615.44 mm2, and its tensile strength is about 27079.36~33849.2 kg.
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:How to determine the welding seam height of steel plate and steel bar?
If the end of the vertical plane and the steel plate welding, welding angle as the bar diameter and the general welding height is 0.7 times the diameter of the arc can be reinforced; if the length direction of the surface of steel plate and steel welding, 2 side fillet weld cracks in the welded steel plate and steel between the full and round steel weldment the maximum diameter of arc phase can be flat.
Q:How many tons of pressure can the round steel of 70 inches bear?
If the steel will generally approximate compressive strength considering tensile strength, even if is only 4 tons / square centimeters, each round cross section of 26 mm diameter is 5.3 cm, maximum 5.3*4 about 20 tons of pressure, the actual use should take into account the safety factor;
Q:Is yuan steel round steel?
Yes.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:12 of the diameter of the round steel can be M12 out of the thread is not
It depends on your material straight straight, generally should be right, you check the metric thread specification table, there is large size can be much, I think you are a little round a little better, so that you may get the car, do not appear to have a side material shortage phenomenon
Q:How is the copper wire and galvanized round steel connected during the construction of the lightning protection device?
Grounding device is an important component of lightning protection device. The earthing device releases the lightning current to the earth, and limits the lightning protection device to the ground voltage not too high. In addition to the independent lightning rod, the grounding device can be shared with other grounding devices on the premise that the grounding resistance meets the requirements.
Q:What is the tensile strength of Q235 round steel?
According to the national standard of GB 13013-1991 reinforced hot rolled round steel bars,Q235 reinforcement
Q:How about the difference between round steel and shaped steel? Where are they mainly used?
Low carbon steel structure steel Q235, Q345 rolled out section is I-shaped, C shape, L shape, flat strip, plate shape... Etc.... Called into "type", as used in steel structure component.
Q:1, three, two, steel, wire rod, round steel what is the difference?
Steel is commonly known as hot rolled ribbed bar, belonging to the small steel steel, mainly used for steel reinforced concrete structure frame. In use, some mechanical strength, bending deformation property and welding performance are required. The raw steel billet for the production of threaded steel is carbon structural steel or low alloy structural steel which is treated by calm melting, and the finished steel bar is delivered in hot rolling forming, normalizing or hot rolling state.
