1. Normalizing is a method of metal heat treatment. It heats steel to a certain temperature and keeps it warm, and then cools it in the air to obtain a heat treatment process that is close to a balanced structure. Its function is to improve the mechanical properties of steel.
2. The normalizing heat treatment of Q345R steel plate is to heat the steel plate to a temperature slightly higher than the Ac3 transformation point (usually 890℃~950℃) after the steel plate is rolled, and then stay at this temperature for a short time and then cool in still air .Normalizing rolling of Q345R steel plate is a rolling method of rolling at normalizing temperature (generally, rolling starts at 1100℃~1200℃, and the final deformation is controlled above 850℃), which can make the state of the material and the specified value of mechanical properties. Same as normalizing heat treatment.
3. Therefore, normalizing rolling actually obtains the microstructure and mechanical properties of normalizing heat treatment through precise temperature-controlled rolling (including final rolling deformation).
