Q:Cold drawn steel wire is a round bar or thread steel in Construction Engineering
Cold drawn steel wire belongs to round bar in building engineering, and it is thread steel after coining. But the material of steel is not good. Who knows what material he made?.
Q:How to recognize high quality thread steel
Inferior steel due to poor production conditions, bulk, no metal signs, no quality guarantee. For safety reasons, we should not buy the inferior steel bars, or go to the direct agents of some famous brand manufacturers, so that the quality is guaranteed. Shandong hundred fertile Steel Pipe Co., Ltd. here recommends that users in the purchase of thread steel, must go to the formal steel business units to purchase, request steel quality certificate, and acceptance.
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:What is the difference between plate and steel?
Steel is commonly known as hot rolled ribbed bar, belonging to the small steel steel, mainly used for steel reinforced concrete structure frame. 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 is the relationship between the price and the hot coil steel prices?
The rebar prices are more special, in addition to energy-saving emission reduction, I personally think that the relationship between market supply and demand. In previous years, coil prices relatively high prices and price, usually in the coil as a goal. I think the price is not reasonable, but I don't understand, because I'm not an expert. Of course, the experts don't understand.
Q:What is the manufacturing process of the hot rolled thread steel production line?
The billets used in continuous small mills are generally continuous billets, the length of which is usually 130~160mm, the length is about 6~12 meters, and the billets are 1.5~3 tons in weight. The rolling line is mostly flat interchange arrangement to realize all round rolling without torsion. According to different billet specifications and finished sizes, there are 18, 20, 22 and 24 small mills, 18 of which are mainstream. The use of bar rolling reheating furnace, high pressure water descaling, in addition to the new technology of low-temperature rolling, endless rolling, rolling, rolling development to adapt and improve the precision of rolling billet, rolling mill is mainly to improve the accuracy and speed (up to 18m/s).
Q:What is the maximum tensile force of 25 thread steel?
The specific parameters of common thread steel are:HRB335: yield strength: 335Mpa, tensile strength 445Mpa, elongation: 17%HRB400: yield strength: 400Mpa, tensile strength 540Mpa, elongation: 16%HRB500: yield strength: 500Mpa, tensile strength 630Mpa, elongation: 15%Ji'nan permanent thread steel tensile strength testing machine, Ji'nan permanent thread steel tensile test machine,
Q:What is thread steel for?
1. nominal diameter range and recommended diameterThe nominal diameter of the thread steel is from 6 to 25mm, and the nominal diameter of the standard steel is 6, 8, 10, 12, 14, 16, 20, 25,, 32, 40 and 50mm.Allowable deviation of surface shape and dimension of 2. ribbed steel discThe ribbed steel bars with ribbed threads shall meet the following basic requirements:The angle between the transverse ribs and the axis of the steel disc should not be less than 45 degrees. When the angle is not greater than 70 degrees, the direction of the cross section of the thread steel is opposite to that of the upper rib on both sides;The transverse rib and the spacing l shall not be greater than 0.7 times the nominal diameter of the steel;The angle between the sides of the transverse rib and the surface of the threaded steel shall not be less than 45 degrees;The sum of the gap (including the width of longitudinal ribs) between the ends of the cross bar and the end of the cross bar of the threaded steel shall not be greater than 20% of the nominal circumference of the thread steel;When the rebar nominal diameter less than 12mm, the relative rib area should not be less than 0.055; the nominal diameter of 14mm and 16mm, the relative rib area should not be less than 0.060; the nominal diameter is more than 16mm, the relative rib area should not be less than 0.065.
Q:Why is thread steel thinner than crude?
Reduce the quality of the project, and the use of low carbon steel instead of rebar. For large engineering projects, often appear to "project inspector", to replace the steel rib steel "Choulianghuanzhu", reduce the construction cost. In the design, because the members allowed to provide "stirrup stress support", the main role is to keep the shape and location of longitudinal reinforcement, steel strapping has a smooth surface, accurate positioning, therefore, in addition to longitudinal reinforcement, licensing round steel stirrups. The longitudinal reinforcement must be made of rib steel.
Q:Does the grade three thread steel with "E" have the same information price as the ordinary three grade thread steel? Is there a big difference?
As far as I know, the price of information may not be divided into "E" and "E", but there are mandatory requirements on the standard. It is estimated that the price will not be much different.
