Precautions for quenching with 高頻加熱機

1.冷卻方式

高頻加熱機淬火的冷卻方式是綜合考慮以下因素確定的：根據鋼材材質、感應加熱的方式、零件的形狀和尺寸等。常用的冷卻方式有：噴淋、浸沒。

射流冷卻：零件由合金鋼製成；

浸沒冷卻：由低合金和碳鋼製成的零件。

2。 頻率

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.加熱溫度

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.

五、加熱方式及工藝操作

1、同時加熱方式

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、連​​續加熱法

這有利於擴大高頻淬火機的應用範圍，連續加熱生產率低，但加熱面積減少，允許降低高頻加熱機的功率（冷卻和加熱是連續的）。
