¿Cuáles son los métodos de recocido comunes para máquinas de recocido de alta frecuencia

1. Incomplete annealing: Incomplete annealing is to heat the iron-carbon alloy to the intermediate temperature of Ac1-Ac3 to achieve incomplete martensitization. With the annealing process of slow cooling. The key to incomplete annealing is suitable for medium and medium carbon steel and high alloy steel forgings, etc.;

2. Spheroidizing annealing: heating the steel to a temperature slightly less than or slightly higher than Ac1 or changing the temperature around A1 for a period of time, and then slowly cooling down. Spheroidizing annealing is used to reduce the high toughness of alloy steel and 45 steel after casting;

3. Isothermal annealing: used to reduce the high toughness of some alloy tool steels with higher nickel and chromium components to carry out drilling production and processing;

4. Recocido completo: mecanismo de sobrecalentamiento grueso con malas propiedades físicas después de la forja, fundición y soldadura eléctrica de acero con alto contenido de carbono;

5. Recocido de alivio de tensión in situ: se utiliza para eliminar la tensión térmica de piezas de fundición y soldaduras de acero;

6. External diffusion annealing: used to equalize the composition of aluminum alloy castings and improve their performance indicators;

7. Work hardening annealing: used to remove the hard bottoming of metal wires and metal sheets during the whole process of cold drawing and cold rolling, and to remove cold work hardening effects to make metal materials soft.

8. Graphitization annealing: high-frequency annealing machine is used to transform pig iron with a lot of cementite into malleable cast iron with excellent plastic deformation. After being heated to a certain temperature, heat insulation and heat preservation for a certain period of time and then moderate cooling, so that the cementite is dissolved to produce high-purity graphite floccules.

Con todo, la máquina de recocido de alta frecuencia puede reducir la resistencia, mejorar el rendimiento del proceso de perforación, calentar lentamente el material metálico a una cierta temperatura, mantenerlo durante un buen tiempo y luego enfriarlo a una velocidad moderada para reducir el fuerza.
