Precautions for quenching with yuqori chastotali isitish mashinasi

1. Sovutish usuli

Yuqori chastotali isitish mashinasini so’ndirishning sovutish usuli quyidagi omillarni har tomonlama hisobga olgan holda aniqlanadi: po’latdan yasalgan materialga ko’ra, indüksiyon isitish usuli, qismlarning shakli va o’lchami va boshqalar Ko’pincha ishlatiladigan sovutish usullari: buzadigan amallar, suvga cho’mish.

Jet sovutish: qotishma po’latdan yasalgan qismlar;

Immersion sovutish: past qotishma va karbonli po’latlardan tayyorlangan qismlar.

2. Chastotani

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. Isitish harorati

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. Isitish usuli va jarayonning ishlashi

1. Bir vaqtning o’zida isitish usuli

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. Uzluksiz isitish usuli

Bu yuqori chastotali söndürme mashinasini qo’llash doirasini kengaytirish uchun foydalidir, uzluksiz isitish unumdorligi past, lekin isitish maydoni kamayadi va yuqori chastotali isitish mashinasining quvvatini kamaytirishga ruxsat beriladi (sovutish va isitish davomiy).
