Introduction


1. Cold-rolled ribbed steel bars are made of hot rolled rod by cold rolling, wire diameter-reducing, a steel bar having one of two or three crescent-shaped face by pressuring ribs and elimination of internal stress. Cold-rolled ribbed steel bar as the prestressed concrete members, it is the new choose instead of cold drawn low carbon steel wire, in-situ concrete structure, you can use grade steel, in order to save steel, it is better one from the common steel material.


 2. Cold-drawn steel refers to a pulling force at both ends of the metal material. The hot-rolled steel cold-drawn equipment with afterburner be tensioned to more than the original steel tensile yield strength stress points, forced tension steel, reinforced plastic deformation so as to improve the yield point strength of reinforced steel and conservation purposes. Cold-drawn steel production process requires two cold-drawn process finished. After cold-drawn yield strength can be increased by 20% -25%, can save 10% -20% of steel, cold-drawn steel is ribbed.


3. Drawing means pulling force is applied at one end of the material, the material through a die hole and pull out the method, the die aperture to be smaller than the diameter of the material. Cold drawing the material in addition to tensile deformation as well as outside extrusion, cold drawing generally carried out in a special drawing machine.

By material than the cold cold drawing process of pulling the material properties can be better cold-drawn steel ribbed or not ribbed
