Hot  rolled steel coil for construction GB Q345B

 

Q:What are the differences between wire rod, round bar and thread steel? Respective specifications?
Wire rods are round, like wire balls. They should be adjusted when they are used. There are usually 6.5 and 8 millimeters in diameter
Q:What is a steel wire rod?
The delivery of long wood is divided into two pieces: fixed gauge and coilYou refer to the wire rod, refers to the coil delivery of steel, under normal circumstances, according to commonly used, refers to the coil delivery of round steel, also known as smooth steel,
Q:If the surface shrinkage of wire rod is poor, what will happen to wire drawing?
In the process of using No. steel, it is mainly broken line, which is caused by surface quality, internal structure, mould, lubrication and so on. Specific reasons for specific analysis.
Q:What is a wire rod?
Wire rods, also known as wire rods, steel, wire, rod (s), usually refer to small diameter round steel discs. The diameter of the wire rod is in the range of 5-19 millimeters (usually 6-9 mm), and its lower limit is the minimum size of the hot-rolled steel section.
Q:How can steel bars and bars be differentiated from each other in different uses?
Round, also known as wire, is round steel with small diameter, the commodity form is rolled into plate supply, on the site in common with diameters of 6, 8, 10, 12 mm, with low carbon steel are generally not used for reinforcement of reinforced concrete structure, much used for steel sleeve, and small diameter for the brick reinforcement of brick concrete structure "".
Q:Use of high carbon steel wire rods
High carbon steel wire rod called hard wire rod, referred to as the hard line, refers to the carbon content of high quality carbon steel wire rod, mainly for the production of carbon structural steel wire, bead wire, steel wire rope, spring, ACSR, prestressed steel wire and steel nail etc.. 60#, 65# and 70# are used to make all kinds of steel nail, steel wire rope, steel strand, hose steel wire, bead steel wire, spring steel wire and so on.
Q:8 wire rods, one meter, how many kilograms?
According to pure theory, the specific gravity of iron is 7.8 grams /cm3, which is about 392 meters long when it is transferred to 8 discs
Q:Is there any difference between the steel bar and the wire rod?
The straight thread steel is divided into three grades, steel material is HRB400, each specification price is: 12-14mm:3270 yuan, 16mm:3220 yuan, 18mm:3140 yuan, 20-32mm:3110 yuan, 36-40mm:3650 yuan. 8-10mm (rolled thread steel): 3210 yuan
Q:What is the diameter of steel wire and the diameter of wire rod, and what's their difference?
The diameter of the steel wire is the diameter of the steel itself, and the diameter of the wire rod is how big it isFor example, you use a 5 mm diameter steel wire coil laps after a large diameter of 1 meters (of course, the middle is hollow)
Q:Can decarburization occur in low carbon and low alloy wire rods? Why?
In addition, when there is surface defect in the continuous casting billet, the decarburization layer of the slab is deformed because of the existence of the defect, so that a small amount of decarburization layer can be preserved in a small amount.However, in the physical and chemical examination, the low carbon steel is not tested by the decarburization layer, and the decarburization occurring in the normal production process is also a small amount of decarburization.
