Advantages and Disadvantages of Hot Rolled Steel and Cold Rolled Steel
Cold Rolled Steel and Hot Rolling Advantages and Disadvantages
In general, the tensile strength, yield strength, plasticity, and toughness of hot rolled steel after overheating treatment will be improved. In addition, heat treatment can eliminate residual stress, while cold rolling may produce residual stress due to the uneven yield deformation of steel during processing, which has a great impact on stability.
Both hot rolling and cold rolling are forming processes of section steel or steel plate, which have a great influence on the structure and properties of steel.
The second disadvantage is the residual stress caused by uneven cooling. The residual stress is the internal self-equilibrium stress without external force, which exists in types of hot rolled steel sections. The larger the section size of the general section, the greater the residual stress. Although the residual stress is self-equilibrium, it has a certain influence on the performance of steel members under external force. Such as hot rolled steel hardness, deformation, stability, anti-fatigue, and other aspects that may have adverse effects.
Cold rolling refers to cold drawing, cold bending, cold drawing, and other cold processing to process steel plates or strips into various types of steel at room temperature. It has the advantages of fast forming speed, high output, and no damage to the coating. It can be made into a variety of cross-section forms to meet the needs of the use conditions; cold rolling can make the steel produce great plastic deformation, thus improving the yield point of the steel.
The first disadvantage is that although there is no hot plastic compression in the forming process, there is still residual stress in the section, which will inevitably affect the overall and local buckling characteristics of the steel.
The second is that the cold rolled section is a generally open section, which makes the free torsional stiffness of the section low. In bending, it is easy to twist, while in compression, it is easy to bend and twist, and its torsional performance is poor.
The third is that the wall thickness of cold rolled steel is small, and there is no thickening at the corner where the plate connects, so the ability to bear a local concentrated load is weak.
