Ukuba ukwi-metal casting, uyazi ukuba iziphene ezibiza kakhulu ezifana ne-porosity, inclusions, okanye iintanda.Izihluzi zeCeramic Foam (CFF) ayizo “izihluzi” kuphela—zisisixhobo esibalulekileyo sokucoca isinyithi esinyibilikisiweyo, ukuphucula ukuthembeka kokuphosa, kunye nokusika inkunkuma yemveliso. Kodwa zisetyenziselwa ntoni kanye kanye? Masicalule izicelo zabo eziphambili ngoshishino kunye nohlobo lwentsimbi, ukuze ubone ukuba zingena njani na ukuhamba kwakho komsebenzi
1. Ukuphoswa kweMetal okungeyoNyoro: Yenza iAluminiyam, iCopper, iZinc Castings zingenasiphako.
Iinsimbi ezingenayo i-ferrous (i-aluminium, ithusi, i-zinc, i-magnesium) isetyenziswa ngokubanzi kwi-auto, i-electronics, kunye ne-plumbing-kodwa i-melts yazo ixhomekeke kwi-oxide inclusions kunye ne-bubbles yegesi. Izihluzi zeCeramic Foam zilungisa oku ngokubambisa ukungcola ngaphambi kokuba zifike kubumba
Ukusetyenziswa Okungundoqo Apha:
Ukusalwa kweAluminiyam (eyona meko yokusetyenziswa enkulu engeyontsimbi):
Izihluzi zisusa i-Al₂O₃ oxides kunye nobutyobo obuncinci kwi-aluminiyam etyhidiweyo, iqinisekisa ukuphosa okugudileyo, okuqinileyo. Igqibelele:
Amalungu omatshini:Amavili, iibhloko zenjini, izindlu zothumelo (iziphene ezimbalwa zithetha ubomi obude).
Amalungu e-Aerospace:I-alloys ye-aluminiyam ekhaphukhaphu kwiifreyimu zenqwelomoya (ifuna intsimbi esulungekileyo kakhulu).
Impahla zomthengi:I-aluminiyam yokupheka, ii-laptop casings (akukho mabala angaphezulu).
Ubhedu kunye neBrass Casting:
Ibambisa ukubandakanywa kwe-sulfide kunye namaqhekeza e-refractory, ukuthintela ukuvuza kwi:
Amalungu emibhobho:Iivalvu, izifakelo, imibhobho (ibaluleke kakhulu ekusebenzeni kokuqina kwamanzi).
Amalungu ombane:Izihlanganisi zobhedu, iitheminali (ubhedu olusulungekileyo luqinisekisa ukuqhuba kakuhle).
IZinc kunye neMagnesium Casting:
Izihluzi zilawula ukwakhiwa kweoksidi kuxinzelelo oluphezulu lokufa (HPDC) lwe:
I-Electronics:Iikesi zeefowuni ze-Zinc alloy, iifreyimu zelaptop ye-magnesium (iindonga ezibhityileyo azidingi ziphene).
Hardware:Izibambo zomnyango weZinc, izixhobo zamandla e-magnesium (umgangatho ongaguqukiyo).
2. Ukuphoswa kweNtsimbi yeFrerous: Lungisa intsimbi, iintsimbi zokuphosa ukuze uSetyenzise umsebenzi onzima
Izinyithi ze-ferrous (intsimbi, intsimbi) zibamba uxinzelelo oluphezulu-kodwa ubushushu bazo obuphezulu bunyibilika (1500 ° C +) zifuna izihluzi ezinzima. Izihluzi zeCeramic Foam apha zibhloka i-slag, amaqhekeza egraphite, kunye neeoksidi eziwonakalisa amandla.
Ukusetyenziswa Okungundoqo Apha:
Intsimbi kunye nokuSasa ngeNtsimbi:
Imelana nentsimbi eshushu inyibilika ukuvelisa iindawo ezithembekileyo ze:
Oomatshini bemizi-mveliso:Iivalvu zentsimbi, imizimba yempompo, iibhokisi zegiya (akukho zintanda zangaphakathi = ixesha lokuphumla elingaphantsi).
Ulwakhiwo:Izibiyeli zolwakhiwo lwentsimbi engatyiwayo, iziqhagamshelo zerebar (zixhathisa ukubola).
Izixhobo zonyango:Izixhobo zotyando zentsimbi, iisinki zasesibhedlele (intsimbi esulungekileyo = ukusetyenziswa ngokukhuselekileyo).
Ukuphosa intsimbi:
Ukuphucula ulwakhiwo oluncinci lwe:
Iimoto:Iidiski zeziqhoboshi zentsimbi ezingwevu, ii-crankshafts ze-iron ductile (izibambo zokukhuhlana kunye netorque).
Izixhobo ezinzima:Iinxalenye zetrektara yentsimbi, imihlathi yesityuyi (ifuna ukuxhathisa).
Imibhobho:Imibhobho yamanzi yentsimbi engwevu (akukho kuvuza kubandakanywayo).
3. I-Special High-Temp Casting: Ukulwa ne-Titanium, i-Refractory Alloys
Ukusetyenziswa okugqithisileyo (i-aerospace, inyukliya), apho iintsimbi zishushu kakhulu (1800°C+) okanye ziyasebenza (i-titanium), izihluzi eziqhelekileyo ziyasilela. Izihluzi zeCeramic Foam (ngokukodwa esekwe kwi-ZrO₂) kuphela kwesisombululo.
Ukusetyenziswa Okungundoqo Apha:
I-Titanium Alloy Casting:
I-Titanium iyanyibilika isabela ngezinto ezininzi-kodwa izihluzi ze-ZrO₂ zihlala zingasebenzi, zenza:
Iindawo ze-Aerospace:Amagqabi enjini ye-Titanium, izixhobo zokumisa inqwelo-moya (ifuna intsimbi esulungekileyo ukuze iphakame).
Ufakelo lwezonyango:Ukutshintshwa kwe-Titanium hip, ukukhutshwa kwamazinyo (akukho ngcoliseko = iyahambelana ne-biocompatible).
I-Refractory Alloy Casting:
Izihluzo ze-non-ferrous superalloys (i-nickel-based, i-cobalt-based) ye:
Ukuvelisa amandla:Iindawo ze-nickel-alloy gas turbine (izibambo ze-1000 ° C + exhaust).
Ishishini leNyukliya:I-Zirconium alloy fuel cladding (ixhathisa i-radiation kunye nokushisa okuphezulu).
Kutheni izihluzi zeCeramic Foam zibetha ezinye iinketho?
Ngokungafaniyo nomnatha wocingo okanye izihluzi zesanti, iiCFFs:
Yiba nesakhiwo se-3D se-porous (ukubambisa ukungcola okungaphezulu, nokuba kuncinci).
Ukumelana neqondo lokushisa eligqithisileyo (1200-2200 ° C, ngokuxhomekeke kwizinto eziphathekayo).
Sebenza ngazo zonke iintsimbi ezinkulu (i-aluminiyam ukuya kwi-titanium).
Nciphisa amaxabiso okulahlwa ngama-30–50% (yonga ixesha nemali).
Fumana iCFF eLungileyo kwityala lakho lokuSebenzisa
Nokuba uphosa iintsimbi zealuminiyam, iivalvu zentsimbi, okanye izifakelo zetitanium, sinezihluzo zeCeramic Foam ezenzelwe iimfuno zakho. Izihluzi zethu zihlangabezana nemigangatho ye-ISO/ASTM, kwaye iqela lethu likunceda ukuba ukhethe izinto ezifanelekileyo (i-Al₂O₃ ye-aluminium, i-SiC yentsimbi, i-ZrO₂ ye-titanium).
Qhagamshelana nathi namhlanje ngesampuli yasimahla kunye nesicatshulwa esiqhelekileyo. Yeka ukulwa nokuphosa iziphene-qalisa ukwenza iindawo ezingenasiphako ngeCFF!
