Product Description
Hot rolling refers to rolling performed above the metal recrystallization temperature.
Recrystallization means that when the annealing temperature is high enough and the time is long enough, strain-free new grains (recrystallization cores) are produced in the fiber structure of the deformed metal or alloy, and the new grains continue to grow until the original deformed structure is completely disappear, and the properties of the metal or alloy also change significantly. This process is called recrystallization. The temperature at which new grains begin to be generated is called the starting recrystallization temperature. The temperature at which the microstructure is completely occupied by new grains is called Final recrystallization temperature, generally what we call recrystallization temperature is the arithmetic mean of the starting recrystallization temperature and the final recrystallization temperature. Generally, the recrystallization temperature is mainly affected by factors such as alloy composition, deformation degree, original grain size, and annealing temperature. Influence.
