Isetshenziselwani i-ferro calcium? 

Uma ubuza nxazonke, uzovame ukuzwa ukuthi nje i-deoxidizer futhi i-desulfurizer ekwenzeni insimbi. Lokho kuyiqiniso, kodwa kufana nokubiza ummese we-Swiss Army nje blade - ugeja i-nuance kanye nobuciko bangempela. Ukwenza lula ngokweqile, ikakhulukazi ku-inthanethi, kucwebezela izinqumo ezibalulekile zokuthi uzosetshenziswa nini, malini, nokuthi yiliphi ibanga, okuyilapho izimpi zezindleko nekhwalithi zinqotshwa noma kulahleke khona.

Beyond Basic Deoxidation: The Practical Nuances

Esitolo sokuncibilika, asigcini nje ngokuphonsa i-calcium eningi ngoba i-spec sheet isho njalo. Isikhathi siyikho konke. Ukuyingeza kusenesikhathi kakhulu, lapho ukugeza kusagcwele umoya-mpilo, kuwukumosha - kudliwa ngaphambi kokuba kwenze umsebenzi wako oncomekayo. Ulinda i-deoxidation yokuqala, ngokuvamile nge-aluminium noma i-ferrosilicon, ukuze uthulise izinto. Khona-ke, i-calcium iyangena. Umlingo wayo wangempela awukona nje ukubamba umoya-mpilo osele; ishintsha okufakiwe. Iphendulela amayunithi ezinhlamvu e-alumina aqinile, abrasive (Al2O3) abe ama-aluminate e-calcium athambile, acwebezelayo. Lona umehluko phakathi kwensimbi ethwalayo ehluleka ngaphambi kwesikhathi kanye nehlala njalo. Ngike ngabona amaqoqo lapho beqile khona ekwelashweni kwe-Ca ukuze bonge amarandi ambalwa, ukuze nje umsebenzi wokudweba ngezintambo ukhungethwe amakhefu - ukonga okumba eqolo.

Isici sefomu le-alloy sibaluleke kakhulu kunalokho abantu abakucabangayo. Sasivame ukusebenzisa izigaxa ngobuningi, kodwa sishintshela ocingweni olunama-cored - lapho i-calcium eningi impushana ipakishwa emgodleni wensimbi - bekuyi-game-changer. Ukujula komjovo kanye nesivuno kube ngcono kakhulu. Uthola i-calcium eningi ekuncibilikeni lapho idingeka khona, hhayi ukushiswa phezulu. Abahlinzeki bayathanda I-Inner Mongolia Xinxin Silicon Industry Co.,Ltd ube nemigqa ephelele yale mikhiqizo, ekutshela ukuthi le ndlela yokulethwa ibe maphakathi kangakanani. Uhlu lwazo, kusukela ku-ferrosilicon evamile kuya ezintanjeni ezikhethekile ezinezintambo, lugqamisa umnyakazo wemboni ekunembeni.

Bese kuba nendaba yesibabule. Yebo, i i-desulfurizer, kodwa ukusebenza kahle kwayo kuhlanganiswe ngokuqinile nesisekelo se-slag kanye nezinga lokushisa. Ku-slag eyisisekelo, ukusebenza kokushisa okuphezulu, ukuhlangana kwe-calcium yesibabule kukhanya ngempela, kwakha i-CaS engena ku-slag. Kodwa uma izimo zakho zivaliwe, awutholi i-desulfurization ejulile oyikhokhele. Kuyithuluzi, hhayi induku yomlingo.

Uxhumano Lokusakaza: I-inoculation kanye ne-Morphology Control

Lapha kulapho i-calcium eningi aphume esitolo sensimbi angene endaweni etholakala kuyo. Ekukhiqizeni i-iron ductile, iyisici esibalulekile ekuhlanganiseni ama-alloys, ngokuvamile nge-magnesium nomhlaba ongavamile. I-calcium isiza ukujova ukuncibilika, ikhuthaze ukwakheka kwe-graphite eyindilinga. Kodwa kuyisenzo sokulinganisa. Kuncane kakhulu, futhi awuwutholi umphumela ogcwele wama-nodularizing; kakhulu, futhi ungakhuphula ukwakheka kwamanyela. Ngikhumbula isilingo esine-inoculant ene-calcium ephezulu eholele ekwakhekeni kwe-slag edabukisayo endaweni ye-ladle kanye ne-crusty ekubunjweni. Siyishayele futhi, ihlanganisa ibanga elihlukile, futhi inkinga yasuswa.

Ama-silicon barium calcium alloys okukhulunywe ngawo abakhiqizi abafana ne-Xinxin Silicon ayisibonelo sakudala salolu hlelo lokusebenza. I-barium kuthiwa yandisa umphumela we-inoculation, ukulwa kuphelile. Ukuthi izindleko ezengeziwe ze-barium ziyafaneleka kuncike ngokuphelele ezikhathini zakho zokubamba kanye nosayizi besigaba sokuphonsa. Okwesigaba esincane, ukulingisa okuthelwa ngokushesha, okujwayelekile i-calcium silicon angenza kahle. Yilolu hlobo lokwahlulela olusebenzayo, oluqaphela izindleko oluhlukanisa i-spec ewusizo kokanjiniyela ngokweqile.

Ngaphandle kwensimbi, ekubunjweni kwe-aluminium, izithasiselo ze-calcium ezihlanzekile zisetshenziselwa ukuguqula i-silicon morphology kuma-al-Si alloys, ukuthuthukisa izakhiwo zemishini. Kuyisilwane esihluke ngokuphelele - izidingo zokuhlanzeka zidlulele - kodwa kukhombisa ukuguquguquka kwento kuyo yonke i-metallurgy.

I-alloying nangaphezulu: Izindima Ezaziwa Kancane

Nakuba kungewona umsebenzi wayo oyinhloko, i-calcium iyingxenye ye-alloying yamabomu kwezinye izinsimbi, njengamamakinadi athile angenawo umthofu. Lapha, i-calcium yenza ama-oxide ayinkimbinkimbi nama-sulfide (njenge-CaO-Al2O3 noma i-CaS) asebenza njengezendlalelo zokugcoba kusixhumi esibonakalayo se-tool-chip ngesikhathi somshini. Kungumphumela ocashile, kodwa emisebenzini yokwenza imishini enevolumu ephezulu, ukuphila kwamathuluzi okunwetshiwe kanye nokukhokha okuthuthukisiwe kokuqedwa kwangaphezulu kokuhlanganisa ingxubevange izikhathi eziningi.

Kukhona nendima yayo ekuhlanzeni insimbi. Ukuguqulwa kokufakwa engikushilo ekuqaleni kumayelana nenhlanzeko. Ukufakwa kwe-globular mancane amathuba okuthi kuvale imibhobho yakho ye-tundish ngesikhathi sokusakaza okuqhubekayo. Inqubo yokulingisa ebushelelezi ifanele isisindo sayo ngegolide, igwema ukuqhuma nesikhathi sokuphumula. Ngakho, ngenkathi sikhuluma i-deoxidizer futhi i-desulfurizer, sikhuluma ngempela ngokuzinza kwenqubo kanye nesivuno.

Ngike ngayibona isetshenziswa kuma-batches okuhlola ukuthola i-titanium noma njengengxenye eyinkimbinkimbi i-deoxidizer ehlanganisiwe ama-blends ahloselwe izinsimbi zomoya-mpilo eziphansi kakhulu ezisetshenziswa ezibucayi. Kulezi zimo, kuyingxenye ye-cocktail eyinkimbinkimbi, hhayi i-ejenti ezimele.

Phansi: Ukuthola, Ikhwalithi, Nokuhlukahluka

Hhayi bonke i-calcium eningi idalwe yalingana. Okuqukethwe kwe-Ca, okuqukethwe kwe-Si, amazinga okungcola (ikakhulukazi u-Al no-C) - konke kusebenza kahle. Inqwaba enosayizi ongahambisani izokunikeza isivuno esingahambisani. Sake saba nomphakeli omsebenzi wakhe wawuhluka kakhulu ngosayizi wezigaxa kangangokuthi amanani ethu okuphakelayo ngezintambo ayegcwele yonke indawo. Sishintshele kumkhiqizi onezicaciso eziqinile zomzimba namakhemikhali, futhi amashadi ethu okulawula inqubo abukeka enempilo kakhulu.

Lapha yilapho ingqalasizinda yenkampani ibalulekile. Umkhiqizi onesethi ephelele yemishini yokuhlola ukunemba, njengoba kuphawulwe encazelweni ka-Xinxin Silicon, akagcini nje ngokuqhosha. Kusho ukuthi bangakwazi (noma kufanele bakwazi) ukuhlinzeka ngokuhlaziywa okuqinisekisiwe, ukuvumelana kwe-lot-to-lot, kanye nokulandeleka. Kumshini wensimbi, lokho kwethembeka kuvame ukuba yigugu kakhulu kunenani eliphansi kancane ngethani ngalinye. Ukushisa okuhlulekile ngenxa yezithasiselo ezingacacisiwe kuyindleko enkulu.

Indawo yokukhiqiza nayo ibalulekile. I-Inner Mongolia iyihabhu le-ferrosilicon nama-alloys ahlobene ngenxa yamandla nokufinyelela kwempahla eluhlaza. Ukuthola okuvela lapho, okuvela kubadlali asebekhulile, kuvame ukusho uchungechunge lokunikezela oluzinzile. Kodwa kusafanele uqinisekise. Uhlelo lokuphatha oluphelele ephepheni aluqinisekisi izinto eziphelele endaweni yesitolo sakho. Hlala uhlola, hlola njalo imithwalo engenayo.

Ukugoqa: Kuyithuluzi Lenqubo, Hhayi Impahla

Ngakho, yini i-calcium eningi usetshenziselwe? Kuyithuluzi lenqubo ye-multifunctional metallurgy. Ukusetshenziswa kwayo okuyinhloko kusekucwengisiseni insimbi ewuketshezi nensimbi, kodwa inani layo lisemininingwane yohlelo lokusebenza ngokuphelele. Imayelana nobunjiniyela bokufakwayo, ukwethembeka kwenqubo, kanye nokusebenza komkhiqizo kokugcina.

Ukucabanga ngakho njengesithasiselo esilula kuyiphutha elikhulu. Udinga ukuqonda amapharamitha enqubo yakho, i-base chemistry, nemigomo yakho yokugcina yomkhiqizo ukuze ukhethe ifomu nebanga elilungile. Ngezinye izikhathi, ingxubevange eshibhile, ene-calcium ephansi yenza umsebenzi. Kwesinye isikhathi, udinga ukuhlanzeka okuphezulu, umkhiqizo opakishwe kahle.

Ekugcineni, kwehlela kulokhu: kuyisihluthulelo esivula imiphumela ethile ye-metallurgical. Futhi njenganoma yimuphi ukhiye, isebenza kuphela uma wazi ukuthi yisiphi isikhiya ongasisebenzisa nokuthi usivula kanjani. Imininingwane evela enkampanini efana I-Inner Mongolia Xinxin Silicon Industry Co.,Ltd ngikunike ukhiye ongahluziwe; umsebenzi we-metallurgist noma unjiniyela we-Foundry usekujikeni.
