Q:What is the specific concept of thread steel through water and what is the difference?
Water cooling technology is used in the production of rebar, and the temperature of controlled cooling termination is higher than the recrystallization temperature of the material. If the temperature is obviously lower than the recrystallization temperature, the surface of the reinforcing steel is easy to form a thin layer of quenching and tempering structure. Quenching and tempering organization once formed, will undermine the strong cuby rebar and welding performance.
Q:What are the listed companies that produce wire rod and thread steel?
The wire in iron and steel usually refers to a coil of wire material with a diameter of 5.5-14. Most of the use of wire coil machine rolled coil supply, it is also known as wire rod or coil. Wire rod is one of the varieties of steel with great dosage. After rolling, it can be directly used for reinforcement and welding structure of reinforced soil, and can also be used again and again. For example, by drawing into a variety of specifications of steel wire, steel wire rope, and then twisted into woven steel wire and winding and heat treatment to the spring; hot and cold forged into cold forging and rolling into rivets and bolts, screws and so on; by cutting into the heat treatment made of mechanical parts or tools; a common wire made of quality carbon steel and carbon steel.
Q:Is cold-rolled ribbed steel bar thread steel?
I haven't heard of cold-rolled steel. Cold rolling is called thin plate
Q:14 screw steel 1 meters multiple?
The performance of classification (class), for example, China's current implementation of standards, (G B1499.2-2007) for steel wire for 1499.1-2008), according to the strength (tensile strength yield point / steel) will be divided into 3 levels; the Japanese industrial standard (JI SG3112), according to the comprehensive performance will be divided into thread steel 5 species; the British Standard (BS4461), also provides some level of performance test of thread steel. In addition, the thread steel can be classified according to the use, such as reinforced concrete, ordinary steel bars and reinforced concrete bars for heat treatment.
Q:8 mm thread steel, how much is a bundle?
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.
Q:What are the marking of the steel bars on the mills? Which factory is the 2LG16 thread?
In the steel mills logo is a symbol to a combination of numbers and letters, according to the strength of steel grade (with digital sign) + mills (referred to as letters marked) + bar diameter (with digital sign) according to the order of size at a certain spacing bar on one side of the uniform by Mark steel the strength grade of the number 2 (two steel), 3 (three steel), 4 (four steel) and other steel label; referred to in letters, such as LG (Lai Gang), JG (Ji Gang), KG (Kunming); diameter of steel bar by the number 12, 14, 16... 25, 28... Etc.. For example, the steel produced by Jigang has a diameter of 22 and the strength grade is 3 grade. The steel mark is 3JG22.
Q:In the concrete floor, how big can the steel bar be replaced by the big screw steel? How to convert?
The strength of the reinforcement to be replaced must be greater than or equal to the original strength of the reinforcement. The tensile strength of the original reinforcement, the square of the diameter * the tensile design strength / the diameter of the reinforcement to be replaced by the square *, the tensile design strength.
Q:What is the quality difference between round bar and screw steel?
Different shape. The outer surface of the round steel is smooth; the outer surface of the spiral steel has a spiral rib. 2. different production standards. In the current standard, round bar that HPB235 grade steel, and its production standards are "hot-rolled smooth steel reinforced concrete" (GB13013); rebar generally refers to HRB335 and HRB400 grade steel, its production standard is "the reinforcement of concrete hot rolled ribbed bar" (GB1499). 3. different strength. The design strength of round steel (HPB235) is 210MPa; the strength of thread steel is higher than that of round bar; the design strength of HRB335 is 300MPa; the design strength of HRB400 is 360MPa.
Q:Do l 8, three grade steel have discs?
If small specifications or hot rolled straight line, the cost is high, not to say, production is still low, the general steel mills in order to produce the production of discoid small threads, and then according to the needs of the use of mechanical processing into a straight bar shape
Q:Laiwu steel thread steel trademark color blue and red Qu Qu
It is suggested that the users must obtain the certificate of quality of steel when they buy the thread steel, and check and accept it. For quality problems, the quality inspection and inspection can be carried out at the professional inspection organization.
