Precautions for quenching with mesin pemanas frekuensi tinggi

1. Metode pendinginan

Metode pendinginan pendinginan mesin pemanas frekuensi tinggi ditentukan oleh pertimbangan komprehensif dari faktor-faktor berikut: sesuai dengan bahan baja, metode pemanasan induksi, bentuk dan ukuran bagian, dll. Metode pendinginan yang umum digunakan adalah: semprot, pencelupan.

Pendinginan jet: bagian yang terbuat dari baja paduan;

Pendinginan Perendaman: Bagian yang terbuat dari paduan rendah dan baja karbon.

2. Frekuensi

The frequency of the high-frequency quenching machine required by different heating processes is also different, but if the frequency we choose is not enough to meet the heating requirements, such as uneven heating, slow heating time, low work efficiency, and the temperature fails to meet the requirements, then It is easy to cause damage to the workpiece.

3. Suhu pemanasan

The suitable heating temperature of the high frequency quenching machine is related to the heating rate, chemical composition and original microstructure of the steel.

Fourth, the technical requirements of parts

The technical requirements of surface quenched parts include: hardened zone distribution, quenched layer structure, quenched layer depth, surface hardness, etc.

5. Metode pemanasan dan operasi proses

1. Metode pemanasan simultan

The advantages of the simultaneous heating method: In order to improve the production efficiency when mass-producing products, this method can be used. Reason: The heated surfaces are co-heated at the same time, and the entire part of the part that needs to be heated is surrounded by the inductor.

2. Metode pemanasan terus menerus

Ini bermanfaat untuk memperluas jangkauan aplikasi mesin pendinginan frekuensi tinggi, produktivitas pemanasan terus menerus rendah, tetapi area pemanasan berkurang, dan kekuatan mesin pemanas frekuensi tinggi dibiarkan berkurang (pendinginan dan pemanasan kontinu).
