Current frequency commonly used in high frequency quenching equipment

The current frequencies commonly used in تجهیزات خاموش کننده فرکانس بالا هستند:

1. گرمایش با فرکانس بالا: 100 ~ 500KHZ، معمولاً 200 ~ 300KHZ استفاده می شود، گرمایش با فرکانس بالا از نوع لوله الکترونیکی است، عمق لایه سخت شدن 0.5 ~ 2.5 میلی متر است، مناسب برای قطعات کوچک و متوسط.

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.
