Sare -chromium Alloy Composite Hammerhead Cr26

 

Madaxa dubbaha sare ee {{0}chromium alloy hammer Cr26 waa qayb muhiim ah oo ka mid ah qalabka wax lagu burburiyo ee mishiinada macdanta. Waxaa inta badan loo adeegsadaa warshadaha qalabka dhismaha sida meelaha dhagaxa laga sameeyo, dhirta sibidhka, iyo miinooyinka, waxaana loo shaqeeyaa in lagu burburiyo agabka adag sida limestone, granite, iyo gangue dhuxusha.

Habka Deminta: Kuleyl ilaa 950 - 1100 darajo, qabo in muddo ah ka dibna si tartiib ah u qabooji si aad u gaadho deminta (tusaale, madaxa dubbaha Cr26 waxa la hayaa 2.5 - 3 saacadood).
Habka kulaylka: Heerkulka hoose- Heerkulka 200 - 260 si meesha looga saaro walbahaarka gudaha
Daawaynta khaaska ah: daawaynta heerkul sare - daawaynta spheroidization heerkul ah 1140 - 1180 darajo 16 saacadood si loo baabi'iyo carbides reticular oo kor loogu qaado adkaanta saamaynta.

 

 

 

Faa'iidooyinka madaxa sare -chromium alloy hammerhead badiyaa waxaa ka mid ah iska caabin aad u fiican, engegnaantiisa sare, adkaanta cas ee sare iyo waxqabadka burburinta heer sare ah. Faahfaahinta waa sida soo socota:

Xiro iska caabin iyo adayg: adkaanta dubbayaasha daawaha chromium sare waxay gaari karaan HRC 58-65. Ka dib daawaynta deminta dusha sare, caabbinta xidhashada si weyn ayaa loo hagaajiyaa. Waxay si gaar ah ugu habboon tahay burburinta alaabta adag sida quartzite iyo granite. Qaab-dhismeedka yar-yar ee maaddadu waxa ay ka kooban tahay carbides eutectic (sida Cr₇C₃), kaas oo sameeya qaab-dhismeed aad u sarreeya oo iska caabin kara xirashada saamaynta ay sababaan walxaha adag. Nolosha adeeggu waa 3-5 jeer ka badan birta manganese ee caadiga ah.
‌
Iska caabbinta saamaynta: Marka lagu daro curiyeyaasha sida molybdenum (Mo) iyo nikkel (Ni) iyo iyada oo loo marayo habka deminta + heerkulka, adkaanta walxaha saldhigga ah ayaa la hagaajiyaa (saameyn adag oo ka weyn ama la mid ah 8 J/cm²), yaraynta khatarta jabka. Intaa waxaa dheer, qaab-dhismeedka isku dhafan (sida birta chromium ee sareeysa + saldhigga birta kaarboon) miisaanno dheeraad ah waxay xirtaan iska caabin iyo iska caabin saameyn leh.

Xasiloonida heerkulka sare -: Curiyaha chromium waxa uu wanaajiyaa adkaanta walaxda heerkul sare (heerka yarayn adayga ee 600 digrii waxa uu ka yar yahay 10%), taas oo ka dhigaysa mid ku haboon jawiga sare ee-ee heerkulku sareeyo- hawlgalada burburinta xawaaraha.
Xaaladaha Codsiga: Inta badan waxaa loo isticmaalaa qalabka sida burburinta saamaynta iyo jabiyayaasha saamaynta, habaynta dhexdhexaadka{0}}alaabta adag (sida limestone iyo quartzite). Marka lagu taageero qaabka dubbe, way yar tahay inuu jabo.
