The Purpose And Principle Of Heating Cold Rolled Ribbed Steel Bars
What is the purpose and principle of heating cold rolled ribbed steel bars? This is questions that a lot of customers who want to invest in cold rolled ribbed steel heating projects are eager to understand. Gongyi Jindi Metallurgical Equipment Co., Ltd is a professional manufacturer of cold rolled ribbed steel machine and cold rolled ribbed steel production line. The technical staff will explain the purpose and principle of heating cold rolled ribbed steel in the following.
The purpose of heating cold rolled ribbed steel bars is to control the various transformations in the internal structure of the steel bars to achieve the desired structure and properties. The internal structure of the ribbed steel bar is an intrinsic factor in determining the performance of the ribbed bar. The performance is only the appearance behavior of the ribbed bar. Heating is an important method to make a significant change in the microstructure and properties of the cold rolled bar.
The principle of heating cold rolled ribbed steel bar is plastic deformation during the cold rolling process. During the plastic deformation, except the mechanical work is used to change the shape of the steel bar, and the rest becomes heating and is lost. About 1% to 10% of the energy is stored in the ribbed steel in the form of various strain energy (such as lattice distortion, dislocation, etc.), so that the internal energy of the metal rises and is in a thermodynamically unstable state. There is a tendency to spontaneously transition to a steady state, which is an internal cause of the change of the cold rolled ribbed steel bar which is heated subsequently. However, at room temperature, the ribbed steel is slow in atomic diffusion. Actually, this change is not observed. Only when the ribbed steel bar is heated to a certain temperature to allow the atom to diffuse, the distortion can be eliminated, so that the deformation is caused by the deformation previously. The elongated and flattened grains - fibrous and other structures and properties return to the state before deformation.
The purpose and principle of heating cold rolled ribbed steel bar is the above. As a manufacturer with experience in the production of cold rolled ribbed steel equipment for years, Gongyi Jindi Metallurgical Equipment Co., Ltd can develop and produce cold rolled ribbed steel bar production lines that meet the requirements of customers with different needs.
