Bamka Centrifugal wuxuu furay impeller ahama birta iyadoo la maalgelinayo,Mashiinka CNCiyo dheellitirka firfircoon.
Tillaabooyinka Habka Qaadista Maalgelinta:
Inta lagu jiro habka shubista maalgashiga, qaabka wax-soo-saarka ayaa lagu dahaadhay walxo dhoobo ah, kaas oo, marka la adkeeyo, qaata joomatari gudaha ah ee tuurista la rabo. Xaaladaha intooda badan, qaybo badan ayaa la isku daraa si ay waxtar sare u yeeshaan iyada oo lagu dhejiyo qaababka shayga gaarka ah ul dhexe ee loo yaqaan sprue. Dhuka ayaa ka dhalaalay qaabka - waana sababta loo yaqaan habka dhunka lumay - iyo biraha dhalaalay ayaa lagu shubaa godka. Marka birta ay adkaato, caaryada dhoobada waa la ruxayaa, taasoo ka tagaysa qaabka saafiga ah ee u dhow ee tuurista la rabo, oo ay ku xigto dhamaystirka, tijaabinta iyo baakadaha.
CF8M waa bir bir ah oo kabka austenitic ah kaas oo daboolaya ASTM A351, ASTM A743 iyo ASTM A744 standard. CF8M oo la mid ah SS 316/F 316 iyo Heerka Shiinaha 0Cr17Ni12Mo2. CF8M waa wax ka beddelka molybdenum sidda ee CF8 daawaha waana kabka u dhigma sameeyay AISI 316 bir aan bir lahayn. Joogitaanka molybdenum waxay kordhisaa caabbinta guud ee daxalka iyo caabbinta u yeelashada chlorides. Daawaha waxaa loo isticmaalaa xaaladaha aashitada khafiifka ah iyo alkaline-ka iyo maaraynta asiidhyada liinta, oxalic iyo fosfooraska. Birta aan daahin CF8M inta badan waxay la mid tahay SS 316, F 316 iyo TP 316. Laakiin waxay ku qeexan yihiin heerar kala duwan, kiimikooyinkooda iyo qalabkooda makaanigana way ka yara duwan yihiin. CF8M waxaa lagu qeexay ASMT A351, ASMT A743 iyo ASTM A744, taas oo loogu talagalay ujeedo kaliya. SS 316 waxa lagu qeexaa ASTM A240 iyo ASTM A276, waxa loogu talo galay saxan, xaashi, xariijin ama baararka birta ah. Fasalka kale waxaa lagu magacaabaa F316, kaas oo ka yimid ASTM A182 qaybo been abuur ah oo kaliya. TP316 waxaa laga heli doonaa ATSTM A376 oo keliya tuubada. Codsiyada ugu muhiimsan ee CF8M waxay tuurayaan daboolka birta ah: impellors, propellers, bamgareynta bamka, weelka waalka iyo taarikada saxaafadda. Daawaynta kulaylka caadiga ah ee CF8M waa Xalka adag iyadoo lagu kululeynayo in ka badan 1900 °F (1040 °C), oo lagu hayo waqti ku filan ka dibna lagu demiyo biyo ama si degdeg ah u qabooji si kale.

Maxaa Loogu Yeedhay CF8M?
Marka loo eego qeexitaanka, xarafka ugu horreeya C macnaheedu waa adeegga loogu talagalay in loogu isticmaalo adeegga u adkaysta daxalka, laakiin mararka qaarkood waxay ka dhigan tahay isticmaalka CASTING sababtoo ah waxaad ka heli doontaa F 316 ASTM A 350 (F = FORGE). Xarafka labaad F waxa uu tilmaamayaa meesha ugu dhow ee daawaha ee jaantuska ternary iron-chromium-nickel (FeCrNi). Isticmaalayaasha garanaya jaantuska, xarafka labaad waxa uu bixiyaa tilmaame ku saabsan birta, nikkel, iyo chromium ka kooban yahay, laakiin dadka intooda badan waa in ay ka helaan macluumaadka alloying ee sifaynta alaabta. Xarfaha saddexaad iyo afraad 8M waxay matalaan inta ugu badan ee kaarboonka la oggol yahay ee cutubyada 0.01% (tusaale, CF8M waxay leedahay ugu badnaan 0.08% kaarboon)
Dulqaadka Qaadashada waxa lagu gaadhi karaa Maalgelinta Qaadista:
Marka loo eego agabka wax-ku-xidhaha ee kala duwan ee loo isticmaalo samaynta qolofka, shubista maalgelinta waxa loo qaybin karaa shubka silica iyo shubista dhalada biyaha. Habka shubista silica sol ayaa leh dulqaadka Cabbiraadda Cabbiraadda (DCT) iyo Dulqaadyada Qaadashada Joomatari (GCT) ka wanaagsan habka dhalada biyaha. Si kastaba ha ahaatee, xittaa iyadoo la raacayo habka wax- shubista, Darajada Dulqaadku waxa ay ka duwanaan doontaa wax kasta oo kabka ah sababtoo ah awooddooda kala duwan. Aasaaskayagu wuxuu jeclaan lahaa inuu kula hadlo haddii aad hayso codsi gaar ah oo ku saabsan dulqaadka loo baahan yahay. Halkan kuwan soo socda ayaa ah darajada dulqaadka guud ee aynu ku gaadhi karno labadaba silica sol iyo hababka shubista dhalada biyaha si gooni gooni ah:
✔ Darajada DCT ee Silica Sol Lost Wax tuurista: DCTG4 ~ DCTG6
✔ Darajada DCT ee Dhalada Biyaha ee Dhuxul Tuuray: DCTG5 ~ DCTG9
✔ GCT Grade by Silica Sol Lost Wax tuurista: GCTG3 ~ GCTG5
✔ Darajada GCT ee Dhalada Biyaha Dhuxul tuurista: GCTG3 ~ GCTG5
