Advantages of Cold Drawn Steel Bar
Convenient construction: The cold drawing connection method is easy to operate in actual construction. Workers only need to prepare the appropriate equipment to connect cold drawn steel bar. There is no need for flame heat treatment and electric welding.
High reliability: The connection formed by the cold-draw connection method is strong and tight. Its strength exceeds the strength of the original steel bar material to a certain extent, thus ensuring the reliability of the connection.
Saving steel: Compared with traditional connection methods, the amount of steel required for cold drawing connection methods is significantly reduced. During the connection process, it is only necessary to leave a short length at each end of the bar to complete the connection. This effectively reduces construction costs.
Low technical difficulty: the equipment and process required for cold drawing are relatively simple, and the technical difficulty is relatively low. The operator only needs to follow the corresponding steps to complete the connection, and the technical requirements are not high.
Performance improvement: The quality and mechanical properties of the rebar are very good, including strength, hardness and wear resistance. At the same time, the factory will further improve the performance of the steel through appropriate heat treatment.
Operation Process of Cold drawn Steel Bar
Material selection: According to the required mechanical properties and size requirements, choose the appropriate steel as the raw material.
Pre-treatment: Necessary inspection and pre-treatment of steel, such as rolling head and rust removal. This ensures its quality and suitability for cold drawing.
Drawing: Workers place the pre-treated steel into a wire drawing machine and stretch it to the required specifications and dimensions through strong drawing.
Rolling: The steel bar after cold drawing is rolled to improve its surface quality.
Heat treatment (optional) : According to the need, the steel bar after cold drawing is properly heat treated to improve its strength and hardness.
