Q:Round steel. Wire rod. Is a high wire a kind of thing?
Wire rod (Rod): coil finished products after hot rolling, including round, square, rectangular, six corners, etc.. Because most of them are round, the wire rod is generally referred to as round wire rod. According to the different material mill was divided into high speed wire (wire) and ordinary wire (P line) two.
Q:Can decarburization occur in low carbon and low alloy wire rods? Why?
Therefore, low carbon alloy steel may also be decarburization, the normal production process and good surface quality, there will be no high carbon steel such as all decarburization layer, but local is also possible!
Q:What is a wire rod?
With the development of production technology, there have been square, hexagonal, fan-shaped and other special-shaped wire rods; the upper limit of diameter has been extended to 38 mm; the plate weight has increased from 40-60 kg to 3000 kg. Because of the development of new heat treatment process, the iron oxide sheet on the wire rod has been obviously thinned, and its microstructure and properties have also been greatly improved.
Q:What is the difference between a wire rod and a straight bar?
Wire rod refers to the delivery of goods in the form of plate delivery, usually with a finer steel, diameter less than 12. When used to straighten, has the advantages of convenient transportation, storage, basically no waste material
Q:If the surface shrinkage of wire rod is poor, what will happen to wire drawing?
If the surface shrinkage of the wire rod is poor, the drawing process will break, because the surface shrinkage is the shrinkage of the cross section, and is the plastic index of the wire rod. Because of the low reduction rate of drawing, it is often less likely to occur because of shrinkage during drawing.
Q:What are the differences between wire rod, round bar and thread steel? Respective specifications?
Round wire, including wire rods, refers to a smooth surface, mainly galvanized round steel, generally 10--12 in diameter, but also of larger diameter but rare. Threaded steel refers to the surface of the thread. Commonly used with diameter 10--25. Generally 2 grade steel
Q:Use of high carbon steel wire rods
High carbon steel wire rod is made of high quality carbon structural steel. It is one of the larger varieties of wire rod.
Q:Is there any difference between the steel bar and the wire rod?
The four grade steel material is HRB500, each specification price is: 12-14mm:3450, 16mm:3430, 18-25mm:3380, 28-32mm:3430, 8-10mm (plate thread steel): 3440 yuan.
Q:Round in high wire and ordinary line what is the difference?
P line: refers to the use of "ordinary mill (usually open-train double wire rod rolling mill)". The rolling speed of 20-60 meters per second, per root weight (disc) in 0.4-0.6 tons (market show is generally three root six head is a market), in the rolling process can only be cooled by air cooling or air cooling line to ensure product performance.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. Of which: 5.5-25 mm small round bars are mostly supplied by straight strips. They are used as reinforcing bars, bolts and various mechanical parts. Round bars larger than 25 millimeters are used mainly for making mechanical parts or for seamless steel tubes.
Q:What is a cold drawn steel wire? What does it usually do?
Ordinary carbon steel hot rolled wire coil diameter of 6.5 or 8 mm at room temperature by using wire drawing die drawing and made the diameters of 3, 4 or 5 mm round steel wire.
