Current frequency commonly used in high frequency quenching equipment

The current frequencies commonly used in izixhobo ezikhawulezayo zokucima izixhobo zezi:

1. Ukufudumeza okuphakamileyo okuphezulu: 100~500KHZ, esetyenziswa ngokuqhelekileyo i-200~300KHZ, luhlobo lwetyhubhu ye-elektroniki yohlobo oluphezulu lokufudumeza, ukuqina kobunzulu be-0.5~2.5mm, ifanelekile kwiindawo ezincinci kunye neziphakathi.

2. 2. Intermediate frequency heating: The current frequency is 500~10000HZ, usually 2500~8000HZ. The power supply equipment is a mechanical intermediate frequency heating device or a silicon controlled intermediate frequency generator. The depth of the hardened layer is 2-10 mm. Suitable for large diameter shafts, medium and large gears, etc. 3. Power frequency heating: The current frequency is 50HZ. Using mechanical power frequency heating power equipment, the depth of the hardened layer can reach 10-20mm, which is suitable for surface quenching of large-diameter workpieces.
