Indlela Yokunciphisa Ukufakwa Kwe-oxide Ekuthweleni Insimbi

Ukufakwa ensimbi kungenye yezinto ezibalulekile ezithinta impilo yokukhathala yokuthwala insimbi. Ukhiye wokulawula ukufakwa kwensimbi ukulawula okuqukethwe kwe-oxygen nama-oxide ensimbi. Imibono esemqoka yokunciphisa ukufakwa kwe-oxide ensimbi imi kanje.

1, Ukulawulwa kokuqukethwe kwekhabhoni ngokuthepha ukuphela kwesithando somlilo sokuqala

Lapho okuqukethwe kwekhabhoni ekugcineni kokuthepha kuphansi kakhulu, umoya-mpilo oncibilikisiwe ensimbi uphezulu, okuholela ekusetshenzisweni kwenani elikhulu le-aluminium ngesikhathi sokuxoshwa okulandelayo, futhi inani eliphelele lokufakwa lizokwanda, okuletha ubunzima ku ukucwengisisa kamuva; Ngaphezu kwalokho, i-oxidizability ye-slag izokwanda ngokusobala, ngakho-ke kunzima ukulungisa nokulawula ukwakheka kwe-slag ekucwengweni kamuva. Kepha okuqukethwe kwekhabhoni okuphezulu kakhulu ekuthepheni ekugcineni kuzoletha ingcindezi ekuqhubekeni kokulawula isithando somlilo sokuqala. Ku-EAF smelting, okuqukethwe kwekhabhoni yokuphela kokuphela kuvame ukulawulwa cishe ngo-0.2%.

2, Ukukhethwa kwe-deoxidizer efanelekayo

Enqubeni yokukhiqiza yensimbi, okuqukethwe oksijini okusensimbi kungancishiswa futhi inani elifanele le-asidi elincibilika i-asidi lingatholwa nge-deoxidation yokugcina ene-aluminium. Lapho okuqukethwe kwe-acid aluminium encibilikayo kuphezulu kakhulu, ukuvikelwa kwensimbi encibilikisiwe akukuhle, okulula ukuholela ku-oxidation yesibili, ngaleyo ndlela kwandise okuqukethwe kwe-brittle Al2O3 inclusions; Lapho okuqukethwe i-asidi ye-asidi encibilikayo iphansi, i-oxidation yesibili ye-silicon nokwehla kwezinga lokushisa lensimbi elincibilikisiwe kuholela ekzikeni komoya-mpilo oncibilikisiwe, okuholela ekwakhekeni kwama-coarse silicate inclusions acebile ku-SiO2. Ngokuya ngocwaningo, lapho okuqukethwe i-asidi e-aluminium encibilikayo ensimbi ilawulwa ku-0.02% ~ 0.04%, usayizi wokusanhlamvu wensimbi ungacolisiswa, ukuze kutholakale amandla nokuqina okuphezulu.

I-Barium isilungisi esihle sokususa i-deoxidizing. Ingxubevange ye-Barium ayinayo kuphela ikhono eliqinile le-deoxidizing, kepha futhi ingakhomba ukufakwa okusalile kwensimbi. Ngokusho kocwaningo, ngemuva kokukhipha insimbi ethwala i-Si Al Ba alloy, ingqikithi yomoya-mpilo osensimbi wehla ngokushesha ube yinani elizinzile. Ekugcineni, ayikho i-barium equkethe ukufakwa kwe-spheroidal ensimbi, futhi okufakwayo okusalile ensimbi kukhonjiswe kahle. Ukufakwa kuhle, kuhlakazekile futhi kwasatshalaliswa ngokulinganayo.

I-Magnesium inomthelela omkhulu ekuguqulweni kokufakwa kwe-Al2O3 ekuthweleni insimbi. Ngokuya ngocwaningo, lapho okuqukethwe i-asidi aluminium encibilikayo ingu-0.03%, kune-210-4% magnesium ensimbi, okungukuthi, ukufakwa kwe-Al 2O 3 kungashintshwa kube yi-MgO · Al 2O 3, kanye Okuqukethwe kweMg ensimbi kungaphezu kuka-10% μ Imiphumela ikhombisa ukuthi i-Al 2O 3 inclusions ene-m iguqulwa yaba yinhle futhi eyindilinga mg Al spinel inclusions, engaphansi kuka-5 μ 46%, eminye ingu-5 ~ 10 μ UM.

3, Ukusebenziswa kokucwenga ukwakheka kwe-slag

Kutholakala ukuthi lapho ubukhulu obunambambili bokucwengwa kwe-slag bukhuphuka busuka ku-2.0 kuye ku-4.5, ingqikithi yomoya-mpilo ekugcineni kwensimbi encibilikile iyancipha isuka ku-20 10-6 kuye ku-11 10-6, futhi inani nenani lendawo yokufakwa inclusions yehla. Ukufakwa okujwayelekile kwensimbi encibilikisiwe eyenziwe nge-slag ephezulu kungukufakwa okufana ne-Al2O3 ne-Al Mg spinel, osayizi wayo ungaphansi kuka-5 μ m. kanye nekhono lokucwenga i-slag kuma-adsorb inclusions.

4, Ukuthuthukisa inqubo yokuncibilikisa

Ukuze uthole insimbi esezingeni eliphakeme, ukwandisa inani lensimbi encibilikisiwe nokukhetha udoti osezingeni eliphezulu wokuncibilikisa izindlela ezisetshenziswa kakhulu. Enkambeni yensimbi yensimbi, ukulawula ngokunembile okuqukethwe kwe-Al, Si noma Ca ngensimbi ukukhuthaza ukususwa kwe-deoxidation kanye ne-desulfurization, kusetshenziswa ukulingisa okuvikelayo kuyo yonke inqubo, okuqukethwe okufakiwe kuzoncishiswa kakhulu. Ukuncibilika komoya kuyindlela ebalulekile yokunciphisa okuqukethwe kokufakwa. Kumshini ophakeme, okuqukethwe komoya-mpilo okwensimbi kungancishiselwa kuye ngaphansi kuka-10-6. Ukuhlanjululwa kwe-Electroslag kungathola ukusebenza kangcono kokuncibilikisa kunokuncibilikisa i-vacuum. Ukucwenga kwe-Electroslag akugcini nje ngokunciphisa okuqukethwe oksijini okusensimbi, kodwa futhi kunciphisa nosayizi wokufakwa kwensimbi, ukuze ukusatshalaliswa kokufakwa kufane kakhulu. Ngemuva kokulungisa kabusha, kunikeza ngamathuba wokufakwa okukhulu kokuntanta phezulu.

Njengamanje, ukufakwa kokuhlanza kanye nokuncibilikisa okusetshenziswayo kusetshenziswa kakhulu ukuthwala insimbi ngezinjongo ezibalulekile ekhaya nakwamanye amazwe. Ukuhlanzeka kwensimbi entsha engenazinsimbi i-6Cr14Mo eyenziwe yile nqubo ithuthukiswe kakhulu, okuqukethwe komoya-mpilo kungu-510-4 kuphela, futhi ukufakwa kwe-oxide kuncane ngobuningi, kuncane ngosayizi futhi kusatshalaliswa ngokulinganayo.

Sicela ugcine umthombo nekheli lale ndatshana ukuze uphinde uprintwe: Indlela Yokunciphisa Ukufakwa Kwe-oxide Ekuthweleni Insimbi

UMinghe Inkampani yeDie Casting anikezelwe ekukhiqizeni nasekuhlinzekeni ikhwalithi nokusebenza okuphezulu Izingxenye Zokulingisa (izingxenye zensimbi zensimbi zokufa zisebenza ikakhulukazi zibandakanya I-Thin-Wall Die Casting,I-Hot Chamber Die Casting,Cold Chamber die Casting), Insizakalo Eyindilinga (Insiza Yokulingisa,ICnc Machining,Ukwenza Okubandayo, Surface Treatment) .Noma ikuphi ukusakazwa kwe-Aluminium die, i-magnesium noma i-Zamak / zinc die casting nezinye izidingo zokuphosa zamukelekile ukuxhumana nathi.
