Precautions for quenching with hoëfrekwensie verwarming masjien

1. Verkoelingsmetode

Die verkoelingsmetode van hoëfrekwensie-verhittingsmasjien-blus word bepaal deur omvattende oorweging van die volgende faktore: volgens die staalmateriaal, die metode van induksieverhitting, die vorm en grootte van die dele, ens. Algemene verkoelingsmetodes is: spuit, onderdompeling.

Straalverkoeling: dele gemaak van legeringstaal;

Dompelverkoeling: Onderdele gemaak van lae-legerings- en koolstofstaal.

2. Frekwensie

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. Verhittingstemperatuur

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. Verhittingsmetode en proseswerking

1. Gelyktydige verhittingsmetode

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. Deurlopende verhittingsmetode

Dit is voordelig om die toepassingsreeks van die hoëfrekwensie-blusmasjien uit te brei, die deurlopende verhittingsproduktiwiteit is laag, maar die verhittingsarea word verminder, en die krag van die hoëfrekwensie-verhittingsmasjien word toegelaat om verminder te word (verkoeling en verhitting is deurlopend).
