Production Flow of 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

Q3: How soon can we receive the product after purchase?

A3: Within three days of placing an order, we will begin production. The specific shipping date is dependent upon international and government factors, but is typically 7 to 10 workdays.

Q4: What makes stainless steel stainless?

A4: 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.

Q:How to distinguish between cold plating and hot rolled round steel?
First of all, the difference between the process is: hot-dip galvanizing is to remove the workpiece, oil, pickling, dipping, drying, immersed in dissolved zinc liquid, a certain time, can be put forward.
Q:The difference between round steel and screw steel
Round steel is a solid strip of steel whose cross section is round. The specifications are expressed in millimeters of diameter, such as "50", which means a round bar of 50 millimeters in diameter.
Q:What is the difference between a circle and round steel continuous casting
Round steel drawn from a continuous casting is called a round billet; the rolled round steel is called a bar.
Q:How many roots are there in a standard ton of steel and how many meters are there in a steel bar?
See more big steel bar, there is theoretical weight. After all, rebar is threaded, and round steel is also used.
Q:What is the mechanical properties of No. 40 round bar?
40# stands for steel grades, round bars for steel profiles, mechanical properties for steels, tensile strength, yield point, (cattle / mm, 2) elongation, shrinkage (%), impact energy, Ak (coke), state, hardness, HB<
Q:What are the main differences between wrought round steel, hot rolled round steel and cold drawn round steel? Where are they used separately?
Round steel three processing methods are more common, should be very wide surface. Hot rolled round steel, used in construction and general hardware parts processing is very common.
Q:The two project is to use rebar or rebar?
Of course, depends on what steel is used for components, such as the two structure of the structure column, and other minor parts, it does not matter. Suggest a slightly larger span of the floor, do not use round steel bar, or the use of thread steel bar, and then with anti crack steel.
Q:How can stainless steel rounds occur? Is it a quality problem?
By the skin bubbles, surface cracks and so on. Crack and steel surface vertical, about 0.8 ~ 1.5mm, no decarburization on both sides, this is caused by the bubble caused by the subcutaneous bubble. The molten steel contains a large amount of gas. When the liquid steel is solidified, the gas is discharged to form bubbles. The outer layer of the slab near the bubble called the subcutaneous bubbles, honeycomb shaped perpendicular to the surface of the billet, billet after rolling, the bubbles inside most welding. But if the subcutaneous bubbles near the slab surface is too close, while heating because of billet surface oxidation or burning of the bubble exposed, the bubble surface is oxidized, thus it is not possible to make the steel welding, surface cracks.
Q:The 8 thread can replace the beam stirrups by steel
Fixed beam and beam is set in the stirrups stirrups, stirrup stirrup is higher than that of the non quota subheadings subheadings, because all trouble making and binding stirrups. In addition, need to see which parts of the ring beam.
Q:How can a round steel weld on a flat steel plate be 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,
