Matambudziko emhando yakajairika uye zvikonzero zvekupisa kupisa kurapwa

Induction heat treatment inzira yekupisa iyo induction current inogadzirwa pamusoro pechikamu kuti ikurumidze kupisa pamusoro pechikamu. Mabhenefiti makuru ekuita uku: kuomarara kwepamusoro kwezvikamu zvakagadziriswa, kumira kwakanaka kwekupfeka uye kuramba kuneta, kuderera kudiki, kubereka kwakanyanya, kuchengetedza simba, uye pasina kusvibiswa. Induction yekupisa kupisa kurapwa kazhinji inosanganisira simbi yakatenderedza (chubhu) kudzima uye kupisa, kudzima kwepamusoro mavhiri ekutungamira, mavhiri ekutyaira, rollers, piston tsvimbo kudzimwa uye kudzikisira, kudzima pini uye kudziya, kureba π danda kudzima uye kudzikamisa, inofambiswa mbiru inodzima uye kupisa, etc.

Matambudziko akajairwa emhando yekurapa kwekupisa kwekupisa ndeaya: kutsemuka, kuomarara zvakanyanya kana kuderera, kuomarara kusina kuenzana, kudzika zvakanyanya kana kudzika zvakanyanya kuomarara layer, nezvimwe. Zvikonzero zvinopfupikiswa sezvizvi:

1. Kutsemuka: kupisa tembiricha yakanyanya, tembiricha isina kuenzana; kutonhora kwakanyanya uye kusina kuenzana; kusarudzwa kwakashata kwekudzima svikiro uye tembiricha; kutsamwa kusingatarisirwi uye kusakwana kushatirwa; zvinhu permeability zvakanyanyisa, zvikamu zvakapatsanurwa, zvakakanganisika, uye zvakawandisa Inclusions; zvisinganzwisisike chikamu dhizaini.

2. Mutambo wakaomeswa wakadzika zvakanyanya kana kudzika: simba rekupisa rakakura kana rakaderera; frequency yesimba yakadzikira zvakanyanya kana yakanyanya; nguva yekudziya yakarebesa kana kupfupika; zvinhu permeability yakaderera kana yakakwirira kwazvo; kudzima tembiricha yepakati, kudzvanywa, Zvisizvo zvisina kunaka.

3. Kuoma kwepamusoro kwakanyanyisa kana kuderera: iyo kabhoni yezvinyorwa zvakanyanyisa kana kuti yakaderera, nzvimbo yacho yakasvibiswa, uye kupisa kwekushisa kwakaderera; kupisa kwekupisa kana nguva yekubata haina kunaka; iyo yekudzima yepakati kuumbwa, kudzvanywa, uye tembiricha hazvina kunaka.

4. Kusaenzana kwepamusoro kuoma: kusinganzwisisiki sensor structure; kusaenzana kupisa; kusaenzana kutonhora; sangano rakashata rezvinhu (banded structure segregation, local decarburization)

5. Kunyungudika kwepamusoro: Chimiro che sensor hachina musoro; zvikamu zvine makona akapinza, maburi, grooves, nezvimwewo; nguva yekupisa yakanyanya kureba; pane kuputika pamusoro pezvinhu.
