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: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:What kind of steel is carbon steel in threaded steel?
Carbon steel. Carbon content of 0.06-0.22%, less than 0.25% is the most common. Of low carbon steel, each of which indicates the minimum yield point of the steel at a thickness of less than 16mm. Compared with high quality carbon steel, carbon content, range of performance, and content of phosphorus, sulfur and other residual elements are wider.
Q:What is the carbon content of thread steel?
It is understood that carbon is the main element determining the performance of steel, because changes in carbon content directly lead to changes in crystal structure. With the increase of carbon content, the strength and hardness of the threaded steel increase, while the plasticity and toughness decrease. When the carbon content is more than 1%, the strength of the rebar decreases. The increase of carbon content also reduces the weldability and corrosion resistance of steel, and increases the cold brittleness and aging tendency of steel.
Q:10 less than three rebar refers to the rebar?
A grade steel is round, without ribs, elongation is the advantage, of course, it also determines its strength is lower than grade three steel.
Q:How is thread steel made?
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). Product specifications are generally phi 10-40mm, Phi Phi 6-32mm or 12-50mm. The steel grades produced are low, medium and high carbon steels and low-alloy steels, which are widely needed in the market. The maximum rolling speed is 18m/s. The production process is as follows:Reheating furnace, roughing mill, rolling mill, rolling mill, water cooling device, cooling bed, cold shear, automatic counting device, bundling machine, unloading bench is calculated from the Shanghai kuanli Steel Co. Ltd. to provide thread steel weight: diameter * * outer diameter theory 0.00617=kg/m theory and 6.50.260 steel manufacturers specifications Jiuzheng 8.00.395 Jiuzheng steel 100.617 steel 120.888 steel 141.21 nine nine nine nine nine steel 161.58 steel 182 steel 202.47 steel 222.98 steel 253.85 nine nine nine nine nine steel 284.83 steel 326.31 steel.
Q:What's the difference between rebar and thread steel?
Physical and mechanical properties are different. Because of the different chemical composition and strength of reinforcing steel, they are different in physical and mechanical properties. The cold bending property of steel is good, can make the hook 180, screw steel can only make straight hook 90 degrees; steel weldability is good, with ordinary carbon steel electrode can be used to low alloy electrode; anti fatigue performance and toughness in steel bar is good.
Q:How to calculate the theoretical elongation of finishing thread steel?
Rebar is a kind of special bar with discontinuous external thread. The steel bar can be connected or anchored at any section with a connector or anchor with internal thread.
Q:12 of the threaded steel can replace 16 of the screw steel? But the same proportion. Thanks
Now Tianjin Tiantai into 12 of the price is 3900 yuan a ton, 16 tons of steel a price is 3850 yuan. 12 of thread steel is 50 yuan more expensive than 16 thread steel.
Q:Why can't grounding steel be used?
When the thread steel is grounded, the contact with the soil is not dense, and the grounding resistance value is increased
