Common steel delivery states are hot rolling, control rolling, normalizing, tempering, annealing, quenching, quenching and tempering - quenching: heating to the phase change point temperature above the process of rapid cooling.Increase the hardness of the material, but decrease the toughness. Normalizing: normal cooling (in air) after heating to above phase transition temperature.Annealing: after heating to the temperature above the phase transition point, cool slowly.Eliminate quenching effect, eliminate stress, uniform composition.Tempering: after quenching, reheating to a certain temperature (lower than the quenching temperature), heat preservation, and then cooling.Uniform composition, slightly reduce hardness, greatly improve toughness.Generally speaking: first annealing, normalizing;Eliminate the effect of original heat treatment.Then quench, then temper.- controlled rolling means controlled rolling.
