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:What are the main use of threaded steel?
Steel is usually used for reinforced concrete, its role is to increase the friction fringe, the rebar and concrete secant integrally formed together, tic phenomenon can not occur in the role of external force, improve the strength of concrete.
Q:Why can not the finish thread steel be welded?
This is generally superior to alloy steel. Carbon content is relatively high, poor weldability, welding conditions are very demanding, but also produce high temperature welding, it is easy to destroy the original material performance. So, under normal circumstances, on-site welding is not allowed.
Q:When did the 1305 rebar contract become a major contract?
1305 rebar contract is now the main contract.
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 difference between three - grade steel and other grades?
Three rebar is the new standard name for HRB400 steel, three steel for the old, as a kind of hot rolled ribbed bar. In construction, three - grade rebar is called the past.
Q:What is the difference between rebar bolts and steel bars?
This question can only be answered: "material should not be compared to components.". Insist on saying the difference, one is the material, and the other is the component.You may ask the difference between soil nail and anchor bar, but the topic is not. I shall be glad to answer another question!
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.
Q:The difference between rebar and crescent
Rebar -- steel used in concrete structures with a generally rounded cross section and ribbed surface.Longitudinal ribs -- uniform continuous ribs parallel to the axis of the steel bar -- other ribs not parallel to the axis of the reinforcement.The longitudinal section of crescent ribbed bars -- transverse rib reinforced crescent, and does not intersect with longitudinal ribs.
Q:Why is the threaded steel thread?
Steel is usually used for reinforced concrete, its role is to increase the friction of thread, the thread steel and concrete secant integrally formed together, tic phenomenon can not occur in the role of external force, improve the strength of concrete.
