Yintoni iCalcium Silicon?

I-silicon ye-calcium, edla ngokubizwa ngokuba yi-CaSi, i-alloy eyenziwe ngokudibanisa i-calcium kunye ne-silicon kunye nesiseko sentsimbi. Isebenza njengento ebalulekileyo ephakathi kwimveliso yensimbi ephezulu kunye nentsimbi. Ngokungafaniyo ne-calcium ecocekileyo, esebenza kakhulu kwaye kunzima ukuyiphatha, i-silicon ye-calcium inikeza ifom ezinzileyo enokuthi ifakwe ngokukhuselekileyo kwiibhafu zetsimbi ezityhidiweyo.

Umsebenzi ophambili wale alloy kukususa ioksijini engafunekiyo kunye nesulfure kwintsimbi engamanzi. Ngokwenza njalo, kuthintela ukubunjwa kwezinto ezinobungozi ezingenayo i-metallic ezinokuthi zinciphise ingqibelelo yesakhiwo sesinyithi. Ubukho bekhalsiyam bukwaguqula ubume bokufakwa okuseleyo, ukuziguqula ukusuka kwimitya emide ukuya kwiifom ezingqukuva ezingenabungozi.

Amashishini athembele i-silicon ye-calcium hayi nje ukucoca inyibilika kodwa ukuphucula ukugalelwa. Kwimisebenzi eqhubekayo yokuphosa, inceda ukuthintela ukuvala umlomo, ukuqinisekisa ukuhamba kakuhle kwentsimbi. Oku kuthembeka kwenza kube lukhetho oluqhelekileyo kubenzi abajolise kumgangatho wemveliso ongaguqukiyo kunye nokusebenza kakuhle.

Ukubunjwa kweMichiza kunye namaBanga

Ukwenziwa kweekhemikhali ze-silicon ye-calcium kuyahluka ngokuxhomekeke kwiimfuno ezithile zenkqubo yokwenza intsimbi. Nangona umlinganiselo we-calcium kwi-silicon unokulungiswa, amabakala orhwebo aqhelekileyo aqulethe phakathi kwe-30% ukuya kwi-60% ye-silicon kunye ne-15% ukuya kwi-30% ye-calcium. Intsalela iqulathe ubukhulu becala intsimbi kunye nezixa-mkhondo ze-aluminiyam, ikhabhoni, kunye nezinye izinto.

• Amabanga aneCalcium ephezulu: Ezi ziqulethe iipesenti eziphezulu ze-calcium, ezinikezela ngezakhono eziphezulu ze-desulfurization. Zihlala zisetyenziswa xa zivelisa i-ultra-low sulfure steels.
• Amabanga asemgangathweni: Ulungelelwaniso olulinganisiweyo olufanelekileyo kwi-deoxidation ngokubanzi kunye nokuguqulwa kokufakwa kwikhabhoni kunye neentsimbi eziphantsi kwe-alloy.
• Ukwahluka kweAluminiyam ephantsi: Icutshungulwe ngokuthe ngqo ukunciphisa umxholo we-aluminium, ukuthintela imiba kwimigangatho yentsimbi e-aluminium-sensitive.

Ukukhetha ibakala elichanekileyo kubalulekile ekwandiseni iindleko kunye nokusebenza.

Isebenza njani iCalcium Silicon ekwenzeni isinyithi

Ukuqonda indlela esemva i-silicon ye-calcium ifuna ukujonga i-chemistry yentsimbi etyhidiweyo. Xa ifakwe kwi-melt, i-alloy iyancibilika ngokukhawuleza, ikhuphe umphunga we-calcium kunye ne-silicon kwi-liquid. Le mpendulo idala imeko-bume ephazamisayo ekhuthaza ukungqubana kunye nokudibana kwe-oxide inclusions.

I-calcium iphendula nge-alumina (Al2O3) inclusions, eqinile kwaye ilungele ukuvala imibhobho. Ngokuguqulwa kweekhemikhali, la masuntswana aqinileyo aguqulwa abe yi-aluminates ye-calcium engamanzi. Ezi zinto zibandakanya ulwelo zidada ukuya kwi-slag layer ngokulula kwaye zisuswe kwindawo yokuhlambela yentsimbi, okukhokelela kwintsimbi ecocekileyo.

Ukongezelela, i-calcium inobudlelwane obuphezulu besulfure. Yenza i-calcium sulfide (CaS), ezinzileyo kwaye ihlale ihlakazekile kwintsimbi okanye idada kwi-slag. Esi senzo se-desulfurization sibalulekile ekuveliseni iintsimbi ezifuna ukuqina okuphezulu kunye nokumelana nokuqhekeka, ngakumbi kwiipleyiti ezishinyeneyo kunye nemibhobho.

Indima yeSilicon kwi-alloy

Ngelixa i-calcium ibamba i-desulfurization kunye nokuguqulwa kokufakwa, i-silicon idlala indima ehambelanayo njenge-deoxidizer eyomeleleyo. Isabela ngeoksijini enyibilikileyo ukwenza i-silica, ethi emva koko idibanise ne-calcium ukwenza iisiliti ezintsonkothileyo. Esi siphumo se-synergistic siqinisekisa ukuba zombini i-oksijini kunye ne-sulfure amanqanaba ayancipha ngaxeshanye.

Umxholo we-silicon nawo uchaphazela ukuxinana kunye nendawo yokunyibilika kwe-alloy. Isiqulatho esiphezulu se-silicon ngokubanzi sehlisa indawo yokunyibilika, sivumela i-alloy ukuba inyibilike ngokukhawuleza kwintsimbi etyhidiweyo. Oku kunyibilika ngokukhawuleza kubalulekile ekuqinisekiseni ukuba umphunga wekhalsiyam unexesha elaneleyo lokusabela phambi kokuba ubaleke kwindawo enyibilikayo.

Ukongeza, i-silicon inegalelo kumandla onke emveliso yentsimbi yokugqibela. Nangona injongo ephambili yokongeza i-CaSi kukucoceka, i-silicon eshiyekileyo isebenza njenge-ejenti yokomeleza, ngobuchule iphucula iimpawu zemishini yezinto ezigqityiweyo ngaphandle kokunciphisa i-ductility.

Inkqubo yokwenziwa kweCalcium Silicon

I-Ferrosilicon ayinayo i-calcium kwaye ayikwazi ukwenza le misebenzi, iyenza ingasebenzi kakuhle ekuveliseni intsimbi ecocekileyo, ekumgangatho ophezulu.

Ngaba i-calcium silicon inokugcinwa ngaphandle?

Hayi, akufanele igcinwe ngaphandle. Isilicon yekhalsiyam idibana nokufuma ukukhupha irhasi yehidrojeni, idale ingozi yomlilo kunye nogqabhuko-dubulo. Kufuneka igcinwe kwindawo eyomileyo, yangaphakathi kunye nendawo yokuphefumla efanelekileyo ukuqinisekisa ukhuseleko kunye nokugcina umgangatho wemveliso.

Ziziphi iintlobo ze-calcium silicon ezikhoyo?

Ifumaneka ngeendlela ezininzi, kubandakanywa amaqhuma, iigranules, umgubo, kunye nocingo olunamaqabunga. Ukukhethwa kwefom kuxhomekeke kwisicelo esithile kunye nesixhobo sokutofa esisetyenziswe sisityalo sensimbi. I-Cored wire iya idume ngokuchaneka kunye nokusebenza kakuhle.

Ngaba i-silicon ye-calcium ikhuselekile ukuphatha?

Ikhuselekile xa iphathwa ngononophelo olufanelekileyo. Abasebenzisi kufuneka bakuphephe ukudibana namanzi kwaye banxibe izixhobo zokukhusela ukuthintela ukuphefumla uthuli. Ukulandela izikhokelo zokhuseleko ezisekiweyo kunye neeprothokholi zokugcina kunciphisa umngcipheko ohambelana nokusebenza kwakhona.

Isiphelo kunye neeNgcebiso zeNgcali

I-silicon ye-calcium imi njengesiseko semathiriyeli yentsimbi yale mihla, ivala umsantsa phakathi kwentsimbi ekrwada etyhidiweyo kunye neemveliso zentsimbi ezisebenza kakhulu. Ubuchule bayo obukhethekileyo bokwenza i-deoxidize ngaxeshanye, i-desulfurize, kunye nokuguqula izinto ezifakiweyo zenza ukuba ingabinandawo ekufuneni ukucoceka kwentsimbi kunye nokusebenza kakuhle.

Kubenzi bentsimbi kunye neziseko, ukusetyenziswa kobuchule kwale alloy kuguqulela ngokuthe ngqo kumgangatho ophuculweyo wemveliso, ukunciphisa ixesha lokuphumla, kunye neendleko eziphantsi zokuvelisa. Nokuba isetyenziswe kwifomu yeqhuma kunyango lweleyidi yesiNtu okanye njengocingo olunabileyo lwenaliti echanekileyo, ixabiso elongezayo kwinkqubo yokwenziwa ayinakuphikiswa.

Ukuba ujonge ukwandisa imisebenzi yakho yokwenza intsimbi, ukuvavanya isicwangciso sakho sokongeza linyathelo lokuqala. Cinga ngokutshintshela kucoceko oluphezulu i-silicon ye-calcium amabanga okanye ukwamkela itekhnoloji yokondla ngocingo ukwandisa amaxabiso okubuyisela. Ukusebenzisana nabanikezeli abathembekileyo ababambelela kwimigangatho engqongqo yomgangatho kuqinisekisa ukusebenza okuhambelanayo kunye nokuxhasa iinjongo zakho zokuvelisa ixesha elide.
