Chii chinonzi ferro calcium inoshandiswa? 

Kana iwe ukabvunza uchitenderedza, iwe kazhinji unonzwa kuti ingori deoxidizer uye desulfurizer mukugadzira simbi. Icho ichokwadi, asi zvakafanana nekudaidza banga reSwiss Army chete blade - rinopotsa nuance uye hunyanzvi chaihwo. Kuwedzeredza, kunyanya pamhepo, kunonamira pamusoro pesarudzo dzakakosha dzekuti riini, ingani, uye giredhi rei rekushandisa, kunova ndiko kunohwinwa kana kurasika mutengo nemhando dzehondo.

Beyond Basic Deoxidation: Iwo Anoshanda Nuances

Muchitoro chekunyungudika, isu hatingokanda mukati ferro calcium nekuti spec sheet inodaro. Nguva ndiyo zvese. Kuiwedzera kare, kana kugeza kuchiri kusango neokisijeni, imarara - inopedzwa isati yaita basa rayo rakanaka. Iwe unomirira yekutanga deoxidation, kazhinji nealuminium kana ferrosilicon, kudzikamisa zvinhu. Zvadaro, calcium inopinda. Mashiripiti ayo chaiwo haasi kungobata okisijeni yakasara; iri kushandura inclusions. Inoshandura yakaoma, abrasive alumina (Al2O3) tambo dzakapfava, globular calcium aluminates. Uyu ndiwo mutsauko pakati pesimbi inotakura inotadza nguva isati yakwana uye inogara. Ndakaona mabhechi kwavakasvetuka pakurapa kweCa kuchengetedza mari shoma, kungove nekuita kwewaya kudhirowa kutambudzwa nemabreak - kuchengetedza kunodhura.

Iyo alloy's form factor inonyanya kukosha kupfuura kufunga kwevanhu. Taishandisa mapundu akawanda, asi kuchinja kune cored waya - uko iyo ferro calcium hupfu hwakazara musheath yesimbi - yaive shanduko-mutambo. Kudzika kwejekiseni uye goho zvakavandudzika zvakanyanya. Iwe unowana yakawanda calcium mukunyunguduka painoda, kwete kupiswa kumusoro. Suppliers vanoda Inner Mongolia Xinxin Silicon Industry Co., Ltd iva nemitsara yese yezvigadzirwa izvi, iyo inokuudza kuti nzira iyi yekuburitsa yave pakati pei. Rudzi rwazvo, kubva kune yakajairwa ferrosilicon kusvika kune yakasarudzika cored waya, inotaridza mafambiro eindastiri kuenda kune chaiyo.

Ipapo pane nyaya yesarufa. Hongu, ndizvo a desulfurizer, asi kushanda kwayo kwakanyatsobatanidzwa ne slag basicity uye tembiricha. Mune yekutanga slag, kupisa kwakanyanya kushanda, kushamwaridzana kwecalcium kune sulfur inopenya chaizvo, ichigadzira CaS inopinda mu slag. Asi kana mamiriro ako akadzimwa, hausi kuwana yakadzika desulfurization yawakabhadhara. Icho chishandiso, kwete chemashiripiti wand.

The Casting Connection: Inoculation uye Morphology Control

Apa ndipo ferro calcium anobuda muchitoro chesimbi opinda muwarika. Mukugadzirwa kwesimbi ye ductile, chinhu chakakosha mukusimbisa ma alloys, kazhinji ane magnesium uye isingawanzo pasi. Iyo calcium inobatsira kuisa inoculate kunyunguduka, kukurudzira kuumbwa kwe spherical graphite. Asi chiito chekuenzanisa. Zvishoma, uye hauwane iyo yakazara nodularizing mhedzisiro; yakawandisa, uye unogona kuwedzera kuumbwa kwemarara. Ndinoyeuka muedzo une high-calcium inoculant iyo yakatungamirira kune zvinosuruvarisa slag buildup mu ladle uye crusty nzvimbo pamusoro castings. Takaifonera zvakare, tichibatanidza mune imwe giredhi, uye dambudziko rakagadziriswa.

Iyo silicon barium calcium alloys inotaurwa nevagadziri vakaita seXinxin Silicon muenzaniso wakasarudzika wechishandiso ichi. Iyo barium inonzi inowedzera inoculation effect, kurwisana kunopera. Kana iyo mari yakawedzerwa yebarium inoruramiswa zvinoenderana zvachose nenguva yako yekubata uye saizi yechikamu chekukanda. Kune yakaonda-chikamu, kukurumidza-kudururwa castings, mwero calcium nesilicon zvinogona kuita zvakanaka. Irwo rudzi urwu rwekutonga, kudhura-kuziva kunopatsanura chinhu chinobatsira kubva kune yakawedzera-injiniya.

Kupfuura simbi, mukukanda kwealuminium, yakakwirira-kuchena calcium additives inoshandiswa kugadzirisa silicon morphology muAl-Si alloys, kuvandudza ma mechanical properties. Icho chikara chakasiyana zvachose - kuchena zvinodiwa zvakanyanyisa - asi inoratidza kuita kwakasiyana-siyana kwechinhu pane simbi.

Alloying uye Kupfuura: Iwo Madiki-Anozivikanwa Mabasa

Nepo risiri iro basa rayo rekutanga, calcium chinhu chine chekuita nemaune mune mamwe masimbi, semamwe magiredhi emahara-emahara machining mamakisi. Pano, calcium inoumba yakaoma oxides uye sulfides (seCaO-Al2O3 kana CaS) iyo inoshanda semafuta ekuzora pane chishandiso-chip interface panguva yekugadzira. Iyo inonyengera mhedzisiro, asi mune yakakwira-vhoriyamu machining mashandiro, iyo yakawedzerwa hupenyu hwechishandiso uye yakagadziridzwa yepamusoro pekupedzisira kubhadhara kweiyo alloy yekuwedzera kakawanda.

Panewo basa rayo pakuchenesa simbi. Kugadziriswa kwekubatanidza kwandambotaura kune chikamu chehutsanana. Globular inclusions kashoma kuvhara tundish nozzles yako panguva yekuramba ichikanda. Iyo yakatsetseka yekukanda maitiro yakakosha huremu hwayo mugoridhe, kudzivirira kuputika uye kuderera. Saka, tichiri kutaura nezvazvo deoxidizer uye desulfurizer, tiri kutaura chaizvo nezvekugadzikana kwemaitiro uye goho.

Ndakatoiona ichishandiswa mumabheji ekuyedza ekutora titanium kana sechikamu mune yakaoma composite deoxidizer misanganiswa yakanangwa kune ekupedzisira-yakaderera okisijeni simbi yeakakosha maapplication. Muzviitiko izvi, chikamu che cocktail yakaoma, kwete mumiriri akazvimirira.

Panyika: Sourcing, Quality, uye Variability

Kwete zvose ferro calcium inosikwa yakaenzana. Izvo zvirimo zveCa, zvirimo zveSi, mazinga ekusachena (kunyanya Al uye C) - vese vanozunguza kuita. Batch ine saizi isingaenderane inokupa goho risingawirirane. Taive nemutengesi kamwechete ane zvinhu zvakasiyana-siyana muhukuru hwebundu zvekuti mafidhiro edu ewaya aive pese pese. Yakachinjirwa kumugadziri ane akaomesesa emuviri uye makemikari specs, uye yedu maitiro ekudzora machati aitaridzika ane hutano.

Apa ndipo panodiwa zvivakwa zvekambani. Mugadziri ane seti yakakwana yemidziyo yekuyedza, sezvakacherechedzwa mune tsananguro yeXinxin Silicon, haasi kungozvitutumadza. Zvinoreva kuti vanogona (kana kuti vanofanirwa kukwanisa) kupa ongororo yakasimbiswa, mijenya-ku-mijenya kuenderana, uye kuteedzera. Kune mugadziri wesimbi, kuvimbika ikoko kunowanzokosha kupfuura mutengo wakaderera patani patani. Kupisa kwakakundikana nekuda kwe-off-spec additives mutengo unotyisa.

Nzvimbo yekugadzira ine basa zvakare. Inner Mongolia inzvimbo yeferrosilicon uye ane hukama alloys nekuda kwesimba uye mbishi kuwana. Kutsvaga kubva ipapo, kubva kune vakasimbiswa vatambi, kazhinji kunoreva yakagadzikana yekugovera cheni. Asi iwe uchiri kufanira kuongorora. Iyo yakakwana manejimendi system pabepa haivimbisi zvinhu zvakakwana pane yako shopu pasi. Gara uchiongorora, gara uchiyedza mitoro inouya.

Kupeta-Up: Icho Chishandiso Chishandiso, Kwete Chigadzirwa

Saka, chii ferro calcium kushandiswa? Icho chinhu chemaitiro akawanda ekugadzira metallurgy. Iko kushandiswa kwayo kwepakati kuri mukunatsa simbi yemvura uye simbi, asi kukosha kwayo kuri mumashoko ekushandisa. Izvo ndezvekusanganisa engineering, kuvimbika kwemaitiro, uye yekupedzisira chigadzirwa kuita.

Kuzvifunga sechinhu chinowedzera chiri nyore ndicho chikanganiso chikuru. Iwe unofanirwa kunzwisisa maitiro ako maparamendi, yako base chemistry, uye yako yekupedzisira chigadzirwa zvinangwa kuti usarudze fomu rakakodzera uye giredhi. Dzimwe nguva, yakachipa, yakaderera-calcium alloy inoita basa racho. Dzimwe nguva, iwe unoda iyo yakakwirira-kuchena, yakanyatsorongedzwa chigadzirwa.

Mukupedzisira, zvinouya kune izvi: kiyi inovhura yakananga mhedzisiro yesimbi. Uye sekiyi chero ipi zvayo, inoshanda chete kana iwe uchiziva kuti ndeipi kiyi yekuishandisa uye nekuibatidza. Izvo zvakatemwa kubva kune kambani yakadai Inner Mongolia Xinxin Silicon Industry Co., Ltd kukupa kiyi mbishi; hunyanzvi hwemetallurgist kana injinjiniya yekuvamba iri mukutendeuka.
