Current frequency commonly used in high frequency quenching equipment
The current frequencies commonly used in معدات تبريد عالية التردد هي:
1. تسخين عالي التردد: 100 500 كيلو هرتز ، شائع الاستخدام 200 ~ 300 كيلو هرتز ، إنه تسخين عالي التردد من نوع الأنبوب الإلكتروني ، عمق طبقة التصلب 0.5 ~ 2.5 مم ، مناسب للأجزاء الصغيرة والمتوسطة الحجم.
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.
