Definition and difference of hot rolling, control rolling and normalizing plate
A, hot rolledAfter a billet is heated, it passes through several passes of rolling, and then the edge is cut and straightened into a steel plate. This is called hot rolling.Hot rolling can destroy the casting structure of steel ingot, refine the grain of steel bar and eliminate the defect of microstructure, so as to improve the microstructure and mechanical properties of steel.This improvement is mainly reflected in the rolling direction, so that the steel is no longer isotropic to a certain extent;Bubbles, cracks and porosity formed during pouring can also be welded under high temperature and pressure.
Second, the controlled rollingThe full name of controlled rolling steel plate is controlled rolling and controlled cooling, referred to as controlled rolling and controlled cooling.Controlled rolling is mainly used for rolling fine grain structural steel, the main principle is that after the final rolling, when the steel plate in the mill running to the "recrystallization" completed parts, water or other media quenching, recrystallization of fine grain size, at room temperature to retain good comprehensive performance.
Third, normalizingNormalizing is a kind of heat treatment process, heat the steel to the phase transition point (AC3 or Acm) more than 40 ℃ ~ 60 ℃ or higher temperature, the heat preservation after reaching complete austenitizing, easy cooled in the air, the heat treatment process of the economy.
