Q:Excuse me, Shagang steel steel, what is the sign of
Steel is known as hot rolled ribbed bar. Ordinary hot rolled steel bars are made up of HRB and the minimum yield point of the brand. H, R, and B are the first letters in English for hot-rolled (Hotrolled), ribbed (Ribbed) and reinforced (Bars) three words. Hot rolled ribbed bar is divided into two levels, HRB335 (old No. 20MnSi), three HRB400 (20MnSiV, 20MnSiNb, old No. 20Mnti), four grade HRB500 three grade
Q:High strength thread steel hrb400e 32 in diameter, is it special steel?
According to the use of special steel, can be divided into high quality carbon steel, alloy steel, carbon tool steel, alloy tool (die) with steel, high-speed tool steel, bearing steel, spring steel (carbon spring steel and alloy spring steel), stainless steel (heat, acid) eight.
Q:What are the different uses of wire rod and thread steel?
The wire is widely used, in addition to the direct reinforcement for building, and also can be processed into various kinds of special wire, such as spring steel wire and wire, galvanized wire, communication wire, steel cord, steel strand, etc.; it can also be processed into other metal products, such as rivets, screws, nails, etc.. According to data statistics, the general national wire output accounted for 5-15% of total steel output. China is now in the period of economic development, and a large number of wire rods are still needed for urban construction and settlement of residents' living conditions. In addition, the domestic demand for metal products increased, and the export volume of international trade continued to expand. China's wire output accounted for about 15% of the total output of steel.
Q:How to judge the quality of thread steel?
Appearance check the necking fracture, peeling, oil pollution, damage, deformation, diameter error, third is the best for the test, according to the provisions of the current "reinforced concrete hot-rolled ribbed bar" GB1499 current national sample sent to the laboratory test, the sample collected for tests of mechanical properties, such as more than three are qualified, steel is good the!
Q:Why is the difference between left and right threads? What's the difference?
Generally, the right-hand thread is in accordance with people's habits, just as the pointer of a clock is right. Compared with the less threaded but is indispensable, it has certain effect, more commonly used threaded on the rotating shaft with a more general rotation shaft are turning to the right, as some pump, motor, fan in the shaft as a tightening wheel for all kinds of leaves threaded, when the impeller rotation relative to the tightening nut, it has a different rotation inertia force, if it is the right-hand thread words will lead to a tightening mother increasingly loose causing impeller loose damaged equipment. This force in the switch machine or a great change in speed when the performance is particularly prominent, so the choice of left-handed thread more and more tight.
Q:Is the theoretical weight of threaded steel and round steel the same?
The rebar is a kind of small section steel, mainly used for the skeleton of reinforced concrete construction members. 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.
Q:What does "4EDT6" mean on thread steel?
It is a long strip of steel with a hollow cross section. It can be divided into round tube, square tube, hexagonal tube and all kinds of special-shaped section steel tube according to its sectional shape. According to the different processing technology, seamless steel pipe and welded pipe can be divided into two categories.
Q:Why does the steel thread have longitudinal ribs?
Thread steel is inaccurate, commonly known as standard "deformed steel bars"". Hot rolled ribbed steel production in China, the surface usually with two longitudinal ribs and transverse ribs along the length direction of the uniform distribution, when the longitudinal section transverse rib crescent, and does not intersect with the longitudinal ribs, called crescent rib reinforced; when the longitudinal section is equal to the height, and with the intersection of longitudinal ribs, said for high ribbed bar. The second and third grade ribbed bars commonly used in engineering usually adopt the crescent rib surface shape.Similar to the screw thread, our country did not produce, it is said that there is such a shape abroad.If it is necessary to say that it is possible to strengthen the tensile and shear strength, because after all, the longitudinal rib expands a little of the cross section of the steel bar. But this is not the purpose of rolling longitudinal rib, the purpose of longitudinal rib is to improve the mechanical performance of the transverse rib.
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:How many patterns are there in threaded steel?
Rebar is ribbed steel, ribbed steel, including rebar. A ribbed steel bar with 2 longitudinal ribs and uniformly distributed ribs along the length. The transverse rib shape is helical, herringbone, crescent 3. Because of the function of rib, it has better bonding ability with concrete, so it can bear the effect of external force better.
