Precautions for quenching with mašina za visokofrekventno grejanje

1. Metoda hlađenja

Metoda hlađenja visokofrekventnog grijanja mašinskog gašenja određuje se sveobuhvatnim razmatranjem sljedećih faktora: prema materijalu čelika, načinu indukcijskog grijanja, obliku i veličini dijelova, itd. Najčešće korištene metode hlađenja su: raspršivanje, uranjanje.

Mlazno hlađenje: dijelovi od legiranog čelika;

Hlađenje potapanjem: dijelovi izrađeni od niskolegiranih i ugljičnih čelika.

2. Učestalost

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. Temperatura grijanja

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. Način grijanja i rad procesa

1. Metoda istovremenog grijanja

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. Metoda kontinuiranog grijanja

Ovo je korisno za proširenje opsega primjene visokofrekventne mašine za gašenje, kontinuirana produktivnost grijanja je niska, ali je područje grijanja smanjeno, a snaga visokofrekventne grijaće mašine je dozvoljeno (hlađenje i grijanje su kontinuirano).
