Хомӯшкунии басомади баланд equipment process method

Rapid heating combined with immediate quench cooling.

Through rapid heating, the surface of the steel to be processed reaches the quenching temperature, and the heat will be rapidly cooled without waiting for the heat to reach the center, so that only the surface layer is quenched into martensite, and the center is still annealed (or positive) with the original unquenched plasticity and good toughness. fire and tempering) tissue.
