Sharaxaada
baararka garaacawaa bir dhumuc weyn leh, sida caadiga ah xoogaa isku dar ah oo chrome ah, kuwaas oo loo sameeyay ujeedada si wax ku ool ah loo jebiyo walxaha sida asphalt, shubka, dhagaxa nuuradda, iwm.
Afuufta baarkawaa qayb muhiim ah inta lagu jiro habka burburintasaameyn toosan usheeda dhexe.Alaabta baararka dharbaaxada waxaa badanaa lagu doortaa iyadoo loo eegayo shaqada burburiyaha saamaynta.
Marka lagu dhejiyo burburiyaha saamaynta toosan, baararka garaaca ayaa la geliyaa meesharotoroo ku wareegay xawaare sare, taasoo ka dhigaysa dhammaan isku-xidhka rotor-ka oo si isdaba joog ah u garaacaya walxaha.Inta lagu jiro hawshan,dharbaaxojabay alaabta ilaa ay ka buuxinayso cabbirka ku habboon si ay uga soo baxdoqolka burburiyaha saamaynta.
Qaybaha Hadhaaga Badelka Dhabta ah - Saamaynta Burburiyaha Burburka Baararka Uu Sameeyay SHANVIM
SHANVIM® waxay bixisaa nashqado kala duwan waxayna soo saartaa xalal kala duwan oo dharbaaxo ah oo loogu talagalay noocyo kala duwan oo OEM ah noocyada burburinta saamaynta tooska ah oo ay ku jiraan: Hazemag, Mesto, Kleemann, Rockster, Master Rubble, Powerscreen, Striker, Keestrack, McClosky, Eagle, Tesab, Finlay iyo kuwa kale. . SHANVIM®"Beddelka Dhabta ah"baararka dharbaaxada waxaa loogu talagalay inay dheereeyaan nolosha xirashada, siinaya ku habboon beddelka saxda ah ee saameynahaaga, iyo kordhinta heerarka wax soo saarka intahoos u dhaca qiimaha-kii-ton.
SHANVIM® Baararka Beedka Beddelka ah ee Loo Heli karo Qaababka Hoos Ku Dhaca
Dhimashada daanka taagan iyo midka dhaqaaqi karo labaduba waxay noqon karaan kuwo fidsan ama jiingado.Guud ahaan, taarikada daanka waxay ka samaysan yihiin bir manganese sare leh taas oo ah qalabka ugu badan ee xidhashada.Birta manganese sare waxa kale oo loo yaqaanaaHadfield manganese birta, bir ka kooban manganese-ku aad u sarreeyo oo lehhantida austenitic.Taarikada noocaan oo kale ah kaliya ma aha kuwo aad u adag laakiin sidoo kale aad bay u dhuuban yihiin oo way ku adag yihiin isticmaalka.
Waxaan bixinaa taarikada daanka ee 13%, 18% iyo 22% darajooyinka manganese oo leh chromium u dhexeeya 2%-3%.Fiiri shaxda hoose ee guryahayaga dhimanaya manganese sare:
Metallurgy of Blow Baars
SHANVIM crusher bir baararka ayaa lagu heli karaa noocyo kala duwan oo biraha ah si ay u daboolaan baahidaada burburin ee gaarka ah.Noocyada kala duwan ee biraha waxaa ka mid ah Manganese, Chrome hooseeya, Chrome dhexdhexaad ah, Chrome sare, Martensitic iyo Ceramic Composite.
Sida ku cad shaxanka, korodhka caabbinta xidhashada birta (adkeydka) waxaa badanaa la socda hoos u dhigista adkaanta (caabbinta saamaynta) ee walxaha.
BIRTA MANGANESE
Iska caabbinta xirashada birta manganese oo leh qaab dhismeed austenitic ayaa loo aaneynayaa ifafaalaha adkeynta shaqada.Saamaynta iyo culeyska cadaadiska ayaa keena adkeynta qaabka austenitic ee dusha sare.Adkeydka bilowga ah ee birta manganese waa qiyaastii.20 HRC.Xoogga saameyntu waa qiyaastii.250J/cm².
Adkeynta shaqada ka dib, adkaanta bilowga ah waxay markaa gaari kartaa ilaa qiyaas ahaan.50 HRC.Lakabyada qotodheer, ee aan weli adkayn ayaa markaa bixiya adkaanta weyn ee birtan.Qoto dheer iyo qallafsanaanta sagxadaha adag ee shaqada waxay ku xiran tahay codsiga iyo nooca birta manganese.
Birta Manganese waxay leedahay taariikh dheer.Maanta, birtan waxaa loo isticmaalaa inta badan daanka burburiya, koollada la jajabiyo iyo qolofyada la burburiyo (mantles & maddiibado).Burburiyaha saamaynta leh, waxa kaliya oo lagu talinayaa in la isticmaalo baararka dharbaaxada manganese marka la burburinayo walxo quudin yar oo aad u weyn (tusaale dhagax nuurad).
chrome birta
Birta chrome-ka ah, kaarboonku waxa uu kiimiko ahaan ugu xidhan yahay qaab karbidhid chromium ah.Iska caabbinta xirashada birta chrome waxay ku saleysan tahay carbides-ka adag ee matrix adag, taas oo dhaqdhaqaaqa ay caqabad ku tahay offsets, taas oo bixisa heer sare oo xoog ah laakiin isla markaaba adag.
Si looga hortago in walxuhu noqdaan kuwo jajaban, baararka dharbaaxada waa in lagu daaweeyaa kulayl.Sidaas awgeed waa in la ogaadaa in heerkulka iyo cabbiraadaha wakhtiga luminaya ay si sax ah ugu dheggan yihiin.Birta chrome waxay caadi ahaan leedahay engegnaanta 60 ilaa 64 HRC iyo awood saameyneed oo aad u yar oo ah 10 J/cm².
Si looga hortago jebinta birta birta ah ee chrome-ka ah, waxaa laga yaabaa inaysan ku jirin wax aan la jabin karin oo ku jira walxaha quudinta.

BIRTA MARTENSITIC
Martensite waa nooc kaarboon-buunsan oo bir ah oo lagu sameeyo qaboojin degdeg ah.Kaliya waxay ku jirtaa daaweynta kulaylka dambe ee kaarboonka laga saaro martensite, taas oo hagaajinaysa xoogga iyo xirashada guryaha.Adag ee birtani waxay u dhaxaysaa 44 ilaa 57 HRC iyo awooda saamaynta inta u dhaxaysa 100 iyo 300 J/cm².
Sidaa darteed, marka la eego adkaanta iyo adkaanta, birta martensitic waxay u dhexeeyaan birta manganese iyo birta chrome.Waxaa loo isticmaalaa haddii culeyska saameyntu uu aad u yar yahay si loo adkeeyo birta manganese, iyo/ama caabbinta xirashada wanaagsan ayaa loo baahan yahay oo ay weheliso iska caabin wanaagsan oo cadaadis ah.
BIRTA BIRTA OO KA MID AH SHEEKADA
Metal Matrix Composites, waxay isku daraan caabbinta sare ee matrixka birta iyo dhoobada aadka u adag.Foomamka daloolka leh ee ka samaysan walxaha dhoobada ayaa lagu soo saaray habka.Baaxadda dhalaalaysa ee macdantu waxay dhex gashaa shabakada dhoobada leh.Waayo-aragnimada iyo aqoontu waxay si gaar ah u tahay habka loo shubo oo la isku daro laba walxood oo kala duwan - bir leh dhumucdiisu tahay 7.85 g/cm³ iyo dhoobada dhumucdeedu tahay 1-3 g/cm³ - oo la isku daray si qotodheer.
Isku dhafkan ayaa ka dhigaya baararka dharbaaxada gaar ahaan xirashada-iska caabinta laakiin isla mar ahaantaana aad u saameyn leh.Iyada oo baararka dharbaaxada laga sameeyay isku-dhafka laga sameeyay beerta ceramics, nolosha adeegga oo ah saddex ilaa shan jeer inta ka mid ah birta martensitic waa la gaari karaa.
