IsiKhokelo seFerro Calcium Silicon: Ukuqulunqwa, usetyenziso kunye neeNgcali zeNgcali 

Ferro calcium silicon sisisidididi esibalulekileyo esidityanisiweyo kunye ne-agent edibeneyo esetyenziswa kakhulu kumashishini anamhlanje okwenza intsimbi kunye ne-Foundry. Idityaniswe ngokuyinhloko ngentsimbi, i-calcium, kunye ne-silicon, le ferroalloy isebenza ngenjongo ezimbini: isusa i-oksijini enobungozi kunye nesulfure kwintsimbi etyhidiweyo ngelixa kwangaxeshanye iguqula i-morphology ye-non-metallic inclusions. Ngokuzisa i-calcium kwi-matrix yensimbi, abavelisi bafezekisa intsimbi ecocekileyo kunye neempawu eziphuculweyo zomatshini, ukuphosa, kunye nomgangatho ophezulu. Esi sikhokelo sinika uhlalutyo olunzulu lokubunjwa kwalo, iinkqubo zokuvelisa, izicelo ezahlukeneyo, kunye nokuqonda kweengcali ekuphuculeni ukusetyenziswa kwayo kwiziphumo eziphezulu ze-metallurgical.

Yintoni i-Ferro Calcium Silicon?

I-Ferro calcium silicon yi-ferroalloy eyinkimbinkimbi edibanisa amandla e-deoxidizing ye-silicon kunye ne-desulfurization ekhethekileyo kunye ne-inclusion-modification ye-calcium. Ngokungafaniyo ne-ferrosilicon eqhelekileyo, ukongezwa kwe-calcium kuguqula kakhulu ukuziphatha kweekhemikhali zokunyibilika. Icandelo le-calcium linobudlelwane obuphezulu be-oksijini kunye nesulfure, zenza iikhompawundi ezizinzile ezinokuthi zihlulwe ngokulula kwintsimbi etyhidiweyo okanye ziguqulwe zibe zingenabungozi, iimilo ze-spherical.

Ukuveliswa kwale ngxubevange ngokuqhelekileyo kubandakanya ukucuthwa kwe-quartz, ikalika, kunye necoke kwisithando somlilo se-arc esingaphantsi kwamanzi, rhoqo kunye nokongezwa kwe-ferrosilicon okanye isinyithi sesilicon njengesiseko. Imveliso ephumayo ayingomxube nje kuphela kodwa i-alloy edityaniswe ngamachiza apho i-calcium izinzile ngaphakathi kwe-silicon-iron matrix. Oku kuzinziswa kubalulekile kuba ikhalsiyam esulungekileyo inendawo yokubila esezantsi kwaye inokuthi ivuthe ngoko nangoko xa idibana nentsimbi enyibilikisiweyo, iyenze ingasebenzi.

Kumxholo we ukucoceka kwentsimbi, isilicon ye-ferro calcium iyimfuneko. Iququzelela ukuguqulwa kwe-alumina inclusions emide, esebenza njengezigxina zoxinzelelo kunye nokunciphisa intsimbi, ibe yi-globular calcium aluminates.

Ngelixa ikhemikhali iyafana, "i-ferro calcium silicon" ibhekisa ngokukodwa kwi-ferroalloy equlethe i-iron matrix ebalulekileyo, esetyenziswa ikakhulu ekwenzeni intsimbi. "I-Calcium silicide" ihlala ibhekisa kwikhompawundi yokubini enentsimbi encinci, ngamanye amaxesha isetyenziswa kwiimeko ezahlukeneyo zeshishini. Kwi-metallurgy, igama elithi ferro calcium silicon libonisa i-deoxidizer edibeneyo edibeneyo.

Ngaba i-ferro calcium silicon ingathatha indawo ye-aluminiyam ukuze ikhutshwe kwi-deoxidation?
Ayilotshintsho oluthe ngqo kodwa liyinto ehambelanayo. I-aluminiyam yi-deoxidizer eyomeleleyo kwaye idla ngokufakwa kuqala. I-silicon ye-Ferro calcium isetyenziselwa ukuguqula i-alumina inclusions eyenziwe yi-aluminiyam kunye nokususa isulfure, i-aluminiyam engenakwenza ngokufanelekileyo.

Ubungakanani bamasuntswana buchaphazela njani izinga lokubuyisela?
Ubungakanani besuntswana bubalulekile. Ukuba iinqununu zincinci kakhulu, zinokuthi i-oxidize kwi-slag okanye ilahleke kwiinkqubo zokuqokelela uthuli. Ukuba zinkulu kakhulu, zisenokunganyibiliki ngokupheleleyo phambi kokuba intsimbi yomelele okanye iphoswe. Ubungakanani obufanelekileyo bobukhulu buqinisekisa ukuba i-alloy ifikelela kubunzulu be-melt kwaye inyibilika ngokufanelekileyo.

Ngaba i-ferro calcium silicon ikhuselekile ukuphatha?
Njengeeferroalloys ezininzi, ivelisa uthuli olunokucaphukisa inkqubo yokuphefumla kunye namehlo. Isenokusabela ngokufuma ukukhupha iigesi ezinokutsha. I-PPE efanelekileyo, ukungena komoya, kunye nokugcinwa okomileyo kunyanzelekile ukuphatha ngokukhuselekileyo.

Ngawaphi amabakala entsimbi azuza kakhulu kule alloy?
I-high-high-high-high-alloy low-alloy (HSLA) iintsimbi, iintsimbi zepayipi, iintsimbi ze-automotive sheet steels, kunye neentsimbi zikaloliwe zizuza kakhulu. Naliphi na ibakala elidinga isulfure ephantsi, ukuqina okuphezulu, kunye nomgangatho obalaseleyo womphezulu uya kubona uphuculo olubonakalayo kunyango lwe-calcium.

Isiphelo kunye neeNgcebiso zeNgcali

I-Ferro calcium silicon imi njengesiseko semathiriyeli ekusukeleni umgangatho ophezulu wentsimbi kunye neemveliso zentsimbi. Isakhono saso esikhethekileyo sokwenza i-deoxidize ngaxeshanye, desulfurize, kunye nokuguqula izinto eziqukiweyo ziyenza ingenakuphinda ithathelwe indawo kwimisebenzi yesinyithi yanamhlanje. Ngokuguqula ukungcola okunobungozi kube ziifom ezintle okanye eziluncedo, kuphucula ukusebenza koomatshini, ukuqina, kunye nokuveliswa koluhlu olukhulu lwamacandelo amashishini.

Kubenzi bensimbi kunye nabaqhubi be-Foundry, isitshixo sokuvula amandla apheleleyo ale ngxubevange kulawulo lwenkqubo echanekileyo. Ukuqonda intsebenziswano phakathi kobushushu, ikhemistri ye-slag, kunye nexesha elongezelelweyo kubalulekile. Abo baziphethe kakuhle ezi zinto ziguquguqukayo banokufikelela ukucoceka kwentsimbi ephezulu, ukunciphisa iindleko zemveliso, kunye nokuhambisa iimveliso ezihlangabezana neyona migangatho ingqongqo yamazwe ngamazwe.

Ngubani ofanele asebenzise le mveliso? Le alloy ilungele abavelisi be-HSLA steels, izinto zombhobho, amaphepha eemoto, kunye ne-high-integrity castings. Ixabiseke kakhulu kumaziko afuna ukuphucula umgangatho wemveliso ngaphandle kokutyala imali kwiziseko ezingundoqo zokutofa ngocingo. Ukusebenzisana nomvelisi onamava afana I-Inner Mongolia Xinxin Silicon Industry Co., Ltd. iqinisekisa ukufikelela kwiimveliso eziphumelele uhlolo olungqongqo ngomgangatho kunye namaziko olongamelo lobugcisa, exhaswa kukuzinikela kwimfezeko kunye nokusebenza kakuhle kobuchwepheshe.

Amanyathelo Alandelayo: Ukuba ujonge ukukhulisa inkqubo yakho yokwenza intsimbi, vavanya amanqanaba akho angoku okubandakanya kunye neethagethi zesulfure. Cinga ngokuqhuba ulingo nge-silicon ye-ferro calcium esemgangathweni ukumisela idosi efanelekileyo yeemeko zakho ze-ladle. Ukusebenzisana nomthengisi obonelela ngohlalutyo lwekhemikhali olungaguquguqukiyo, uluhlu lweemveliso ezahlukeneyo ezibandakanya ii-noduzers kunye neengcingo ezicoliweyo, kunye nenkxaso yobugcisa ezinikeleyo iya kuqinisekisa ngakumbi impumelelo yakho ekuveliseni iintsimbi ezikumgangatho wehlabathi.
