Precautions for quenching with high frequency umshini wokushisa

1. Indlela yokupholisa

Indlela yokupholisa yokucima umshini wokushisisa imvamisa ephezulu inqunywa ngokucutshungulwa okuphelele kwalezi zici ezilandelayo: ngokwezinto zensimbi, indlela yokushisa okungeniswayo, ukuma nobukhulu bezingxenye, njll. Izindlela zokupholisa ezivame ukusetshenziswa yilezi: fafaza, ukucwiliswa.

Ukupholisa i-Jet: izingxenye ezenziwe ngensimbi ye-alloy;

Ukupholisa Okucwiliswayo: Izingxenye ezenziwe nge-alloy ephansi nezinsimbi ze-carbon.

2. Imvamisa

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. Ukushisa kokushisa

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. Indlela yokushisa nokusebenza kwenqubo

1. Indlela yokushisa ngesikhathi esisodwa

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. Indlela yokushisa eqhubekayo

Lokhu kunenzuzo ekwandiseni uhla lwesicelo somshini wokucisha imvamisa ephezulu, ukukhiqizwa kokushisa okuqhubekayo kuphansi, kodwa indawo yokushisa iyancipha, futhi amandla omshini wokushisa we-high-frequency avunyelwe ukuba ancishiswe (ukupholisa nokushisa kukhona. okuqhubekayo).
