Information

        The normalizing process of the normalizing furnace is essentially a special case of annealing. the difference between the two is mainly that the cooling rate is faster and the degree of under cooling is faster, so a pseudo-eutectic transformation occurs, which increases the amount of pearlescent in the tissue and the interlamellar spacing of pearlescent pearls becomes smaller. It should be pointed out that some high alloy steel is air-cooled, the bainite or martensite structure can be obtained. This is because the supercooled austenite of the high alloy steel is very stable, and the C curve.

        Normalizing furnace heat treatment is a heat treatment method in which steel is heated to above the critical temperature to transform the steel into uniform austenite, and then naturally cooled in the air. It can eliminate the network cementite of hypereutectoid steel. It can refine the crystal lattice of hypoeutectoid steel and improve the comprehensive mechanical properties. It is more economical to replace the annealing process with normalizing for less demanding parts.

 
 
   Due to the structural characteristics of the normalizing furnace, the strength, hardness and toughness after normalizing are higher than those after annealing, and the plasticity is not reduced. Compared with annealing, normalizing steel has high mechanical properties, simple price increase, short production cycle and low energy consumption. Therefore, when possible, normalizing furnace heat treatment technology should be given priority
