Izizathu zokuba kutheni ubulukhuni be ukwenziwa lukhuni iinxalenye azihlangabezani neemfuno zobugcisa

1. Ubushushu bokucima akwanele

Okokuthi, ukufudumeza akwanelanga kwaye imfuneko yokushisa kwe-austenitizing ayifikeleleki. Kwintsimbi yesakhiwo sekhabhoni ephakathi, kukho i-ferrite enganyibilikiyo kwi-austenite, kwaye kukho i-ferrite enganyibilikiyo kwisakhiwo esicinyiweyo ngaphandle kwe-martensite, kunye nomphezulu ocinyiweyo we-workpiece uhlala uluhlaza okwesibhakabhaka. Inokubonwa kwakhona kwimbonakalo ye-induction yamacandelo aqiniweyo ukuba indawo eqhelekileyo ecinyiweyo yi-beige, kwaye i-overheated surface imhlophe.

2. Ukupholisa okungonelanga

Oko kukuthi, isantya sokupholisa sisezantsi kunomlinganiselo obalulekileyo wokupholisa. Kwisakhiwo esicinyiweyo, ngaphezu kwenxalenye ye-martensite, kukho i-tortenite, kwaye ubuninzi be-tortenite, buphantsi ubunzima. Ngokuqhelekileyo kwenzeka xa ukugxininiswa kwendawo yokucima, ubushushu, utshintsho loxinzelelo kunye nomngxuma wenaliti yolwelo uvaliwe.

3. Ubushushu bokuzibamba buphezulu kakhulu

Ingxaki yobushushu bokuzibamba ngokugqithisileyo kwenzeka kwi-shaft scanning quenching, eyenzeka ngokubanzi ngexesha lokucinywa kweshafti ethe tye okanye ukucinywa kweshaft ethe nkqo. Xa ububanzi bejethi yolwelo bufutshane, indawo yokufudumeza idlula ngokukhawuleza ijethi yolwelo kwaye ayipholisi icandelo lokucima ngokwaneleyo, kwaye ukuhamba kwamanzi kuvaliwe ngamanyathelo (icandelo elikhulu le-diameter liphezulu, icandelo elincinci le-diameter. isezantsi), kwaye icandelo elicinyiweyo alinakuqhubeka nokupholiswa. Ngenxa yoko, ubushushu obubonakalayo bokuzibamba buhlala bubonwa kwaye bubonwa kwindawo ecinyiweyo.

4. Indawo ethambileyo okanye ibhanti elimnyama elijingo

Iindawo ezithambileyo kunye neebhloko kumphezulu ocinyiweyo zihlala zimnyama, kwaye ibhanti elimnyama elijikelezayo lisisiphene esiqhelekileyo sokuskena iindawo ezicinyiweyo. Eli bhanti limnyama likwabizwa ngokuba yi-soft band, kwaye lihlala lisisakhiwo se-tortite. Isisombululo kukutshiza i-liquid ngokulinganayo, kwaye ukwandisa isantya sokujikeleza kwendawo yokusebenza kunokunciphisa i-pitch yebhanti elimnyama, kodwa eyona nto isisiseko kukuba isakhiwo se-sprayer yamanzi kufuneka senze indawo yokufudumala ipholile ngokulinganayo. Imingxuma yejethi evalekileyo idla ngokuba yenye yezizathu zamachokoza athambileyo.

5. Impembelelo yezinto eziphathekayo zekhemikhali

Ukunciphisa ukubunjwa kwezinto eziphathekayo, ngokukodwa umxholo wekhabhoni, yenye yezinto zokunciphisa ubunzima. Ukuba kuyimfuneko, umxholo wekhabhoni okhethiweyo ungasetyenziselwa iindawo ezibalulekileyo, ukwenzela ukuba imida ephezulu kunye nesezantsi ye-w (C) inokucuthwa ukuya kwi-0.05%.

6. Ukulungiselela unyango lobushushu

Utshintsho kwinkqubo yokucima kunye nokufudumala, kunye nesikhumba esimnyama sezinto eziqengqelekayo sihlala kwindawo yokucima kwakhona zizathu zokuba ubunzima be-induction lukhuni iindawo azihambelani neemfuno zobugcisa.

7. I-surface decarburization kunye ne-decarbonization

Ihlala isenzeka kumphezulu wezinto ezitsalwa ngokubanda. Ngoko ke, emva kokucima le mivalo, umaleko wangaphandle unokucolwa ngo-0.5mm ngaphambi kokuqina. Ukuba ubunzima bomhlaba buphantsi, ubulukhuni bangaphakathi buphezulu kunomgangatho, okubonisa ukuba kukho i-carbon-depleted or decarburized layer. (ngaphandle kweejometri ezikhethekileyo ezifana ne-cam lobes, i-gear top).

8. Iribhoni yethishu yamandulo

Isakhiwo esibhantiweyo kwisakhiwo sokuqala senxalenye ecinyiweyo siya kukhokelela ekuqineni okwaneleyo emva kokucima. Kukho i-ferrite enganyibilikiyo kwisakhiwo esidibeneyo, esingenakuchithwa ngexesha lenkqubo ye-austenitization, kwaye ubunzima emva kokucima kufuneka bunganelanga, kwaye isakhiwo esidibeneyo sinzima ukuphelisa nangona ukushisa kokufudumala kwanda.
