Ubuchwepheshe bokukhiqiza ama-graphite ama-braptibles for smelting wethusi uguqulwa. Le nqubo isebenzisa indlela yokucindezela ebandayo ethuthuke kakhulu emhlabeni futhi yakhiwa ngaphansi kwengcindezi ephezulu ye-600MPA ukuqinisekisa ukuthi ukwakheka kwangaphakathi kwe-ebethelwe kufana nomfaniswano kanye nokungaphezulu kakhulu. Lokhu okusha akugcini nje ngokuthuthukisa ukusebenza kwecala lokucacisa, kodwa futhi kwenza impumelelo enkulu ngokulondolozwa kwamandla nokuvikelwa kwemvelo.
Izinzuzo zokucindezela okubandayo okukhona
Isakhiwo sangaphakathi sifana futhi singenacala
Ngaphansi kokubumba kwengcindezi ephezulu, ukwakheka kwangaphakathi kwe-graphible ye-Copper-i-braphible kuyunifomu kakhulu ngaphandle kwezici. Lokhu kuhluke ngokuphelele ezindleleni zokusika zendabuko. Ngenxa yengcindezi ephansi, izindlela zendabuko ziholela ekutheni izinkinga zangaphakathi ezihlekisayo ezithinta amandla alo nokusebenza okushisayo.
Amandla aphezulu, udonga oluncane olusebenzayo
Indlela yokucindezela ebandayo enobunzima kakhulu ithuthukisa amandla e-Earcidible ngaphansi kwengcindezi ephezulu. Amandla amakhulu avumela izindonga ezinokwenziwa zenziwe zinciphise, ngaleyo ndlela zikhulise ukuqhutshwa okushisayo kanye nokunciphisa ukusetshenziswa kwamandla. Uma kuqhathaniswa nama-turribles wendabuko, lolu hlobo olusha lwe-Earccible lufanelekile ukukhiqizwa okusebenzayo kanye nezidingo zokonga amandla.
Ukusebenza okuhle kakhulu okushisayo kanye nokusetshenziswa kwamandla okuphansi
Amandla aphezulu kanye nokwakheka odongeni olubi ngodonga lwama-graphite we-graphite we-molten yethusi kuphumela ekusebenzeni okungcono kakhulu okushisayo okuqhathaniswa nama-eartibles. Ukwenza ngcono ukuvumelanisa okushisayo kusho ukuthi ukushisa kungadluliselwa ngokulinganayo futhi ngokushesha ngesikhathi senqubo yokunqwabanisa yama-aluminium alloys, ama-allwoys we-zinc, ngaleyo ndlela anciphise ukusetshenziswa kwamandla kanye nokwenza ngcono ukukhiqiza.
Qhathanisa ngezindlela zokukhiqiza zendabuko
Ukulinganiselwa Kwezindlela Zokusika
Iningi lama-graphite akhiqizwa ngaphambi kwe-graphite akhiqizwa ngokusika abese esona. Le ndlela iphumela ezinhlakeni zangaphakathi ezingenaphutha, ezingenaphutha, ezinamandla ngenxa yokucindezela okuphansi. Ngaphezu kwalokho, kunokuvuselelwa okungekho emthethweni kanye nokusetshenziswa kwamandla okuphezulu, okwenza kube nzima ukubhekana nezidingo zemboni yanamuhla ukusebenza kahle kanye nokulondolozwa kwamandla.
Okubi Kwemilitha
Abanye abakhiqizi balingisa indlela ecindezelayo ebandayo yokukhiqiza ama-turvibles, kepha ngenxa yengcindezi enganele yokukhiqiza, iningi labo likhiqiza ama-sericon carbide ama-rucibles. Lezi zimpukane zinezindonga ezinkulu, ukuqina okungekho emthethweni, nokusetshenziswa kwamandla okuphezulu, okukude kakhulu kusuka kuma-graphible we-graphible we-graphible angempela abunjiwe akhiqizwa ngokucindezela okubandayo okukhona.
Izimiso Zobuchwepheshe kanye Nezicelo
Enqubweni yokunqwabanisa ye-aluminium ne-zinc alloys, ukumelana no-oxidation kanye nokuvuselelwa okushisayo kwababekile yizinto ezibalulekile. Ama-Crucibles akhiqizwa esebenzisa indlela ebandayo yokucindezela ama-Isstatic Beka ukugcizelela okukhethekile ekumelaneni ne-oxidation ngenkathi ugwema imiphumela emibi ye-fluoride fluxes. Lezi zinwele zigcina ukusebenza okuhle kakhulu emazingeni okushisa aphezulu ngaphandle kokungcolisa insimbi, ngcono kakhulu ukuqina.
Isicelo e-Aluminium Alloy Smoreng
I-graphite enyathelwa idlala indima ebalulekile ekuncibilikiseni kwama-aluminium alloys, ikakhulukazi ekukhiqizweni kokuphonswa nokukhokhwa kwentela. Ukushisa okuncibilikayo kwe-Aluminium Alloy kuphakathi kuka-700 ° C no-750 ° C, okubuye kube yibanga lokushisa lapho i-graphite isebenza kalula. Ngakho-ke, ama-graphite ama-brucIbles akhiqizwa yindawo ecindezelayo ebandayo egcizelele ukugcizelelwa okukhethekile kokumelana ne-oxidation ukuqinisekisa ukusebenza okuhle kakhulu emazingeni okushisa aphezulu.
Yakhelwe izindlela ezahlukahlukene zokuncibilika
I-graphite egqoke kahle ilungele izindlela ezahlukahlukene zokubhema, kufaka phakathi ukunyibilika okuphelele okuphelele nokukhala okuhlanganiswe nokulondolozwa kokushisa. Okwezinkomba ze-aluminium alloy, ukwakheka okusebenzayo kudinga ukufeza izidingo zokuvimbela ukutholwa kwe-H2 kanye ne-oxide ukuxuba, ngakho-ke kusetshenziswe okubekiwe noma okubunjiwe okubunjiwe komlomo. Emaceleni emaphakathi amancanyana, ukuthambisa izimpande ezisebenzayo kuvame ukusetshenziselwa ukuguqula imfucuza yokunqwabelana.
Ukuqhathaniswa kwezici zokusebenza
Ubuningi obuphakeme kanye nokuvuselelwa okushisayo
Ubuningi bama-graphite ama-brucibles akhiqizwa ngokucindezela okukhankasweni okubandayo kuphakathi kuka-2.2 no-2.3, okungukuthi ubukhulu obuphakeme kakhulu phakathi kwe-tucibles emhlabeni. Lokhu kubulwa okuphezulu kunikeza i-arfectivity enobuhlakani obuhle kakhulu, engcono kakhulu kunezinye izinhlobo zezinhlobo ze-rucibles.
Ukumelana nokugqwala nokugqwala
Ingaphezulu le-graphin ye-aluminium ebilisiwe limbozwe ngezendlalelo ezine ze-glaze coating ekhethekile, okuhlangene, okuhlanganiswe nezinto eziningi zokubumba, kuthuthukisa kakhulu ukumelana nokuphikiswa kwempilo yayo. Ngokuphambene nalokho, ama-crucibles asekhaya anesendlalelo sokwenza usimende oqinisiwe kuphela ebusweni, okulinyazwa kalula futhi kubangela kalula i-opidation yangaphambi kwesikhathi sokubaleka.
Ukwakheka kanye nokuvuselelwa okushisayo
I-graphite ebiwe ye-molten isebenzisa i-graphite yemvelo, enobuhlakani obuhle kakhulu obushisayo. Ngokuphambene, ama-graphite ama-graphite asekhaya asebenzisa i-graphite yokwenziwa, anciphise okuqukethwe kwe-graphite ukunciphisa izindleko, bese wengeza inani elikhulu lobumba lokubumba, ngakho-ke ukuthuthuka okushisayo kuncishiswa kakhulu.
Izindawo zokupakisha nezicelo
Ukufaka ndawonye
Igrafu ye-molten yethusi enobuthi ivame ukuhlanganiswa futhi ifakwe ngentambo yotshani, okuyindlela elula futhi engokoqobo.
Ukunwetshwa kwezinkambu zohlelo lokusebenza
Ngokuthuthuka okuqhubekayo kobuchwepheshe, izinkambu zohlelo lokusebenza lwe-graphite ama-brucibles ziyaqhubeka zikhula. Ikakhulu ekukhiqizweni kwe-aluminium alloy die castings kanye nokukhokhiswa, ama-graphite ama-grupibles athatha indawo yezimbiza zensimbi yendabuko ukuze ahlangabezane nezidingo zokukhiqiza zezimoto ezisezingeni eliphakeme.
Ekuphetheni
Ukusetshenziswa kwendlela yokucindezela ebandayo ebabandayo kulethe ukusebenza kanye nokusebenza kahle kwe-Copper-graphite scariable smelling ezingeni elisha. Noma ngabe kungukufani, amandla noma ukuthuthuka okushisayo kwesakhiwo sangaphakathi, kungcono kakhulu kunezindlela zokukhiqiza zendabuko. Ngohlelo lokusebenza olusakazekile lwalobu buchwepheshe obuthuthukisiwe, isidingo semakethe se-graphite ama-trucibles sizoqhubeka ukwandisa, ukushayela imboni yonke ngekusasa elisebenzayo nelinemvelo.
