Isetyenziselwa ntoni i-ferro calcium? 

Ukuba ubuza ngeenxa zonke, uya kuva ukuba yinto nje i-deoxidizer kwaye i-desulfurizer ekwenzeni intsimbi. Yinyani, kodwa kufana nokubiza imela yoMkhosi waseSwitzerland nje ngencakuba-iphosa i-nuance kunye nobugcisa bokwenyani. Ukwenziwa lula kakhulu, ngakumbi kwi-intanethi, kutyhila izigqibo ezibalulekileyo zokuba nini, malini, kwaye leliphi ibakala ekufuneka lisetyenziswe, kulapho iindleko kunye namadabi asemgangathweni aphunyelelwayo okanye alahlekileyo.

Ngaphaya kweSiseko sokuDityaniswa kwe-Deoxidation: IiNuances eziSebenzayo

Kwivenkile enyibilikayo, asiphosi nje i-calcium ephantsi kuba iphepha elikhethekileyo litsho njalo. Ixesha liyinto yonke. Ukuyongeza kwangethuba, xa ibhafu isesendle neoksijini, yinkunkuma – iyatyiwa ngaphambi kokuba yenze umsebenzi wayo ophucukileyo. Ulinda i-deoxidation yokuqala, rhoqo nge-aluminiyam okanye i-ferrosilicon, ukuzola izinto. Emva koko, i-calcium ingena. Umlingo wayo wangempela awugcini nje ukubamba i-oksijini eseleyo; ilungisa ukubandakanywa. Ijika i-alumina eqinile, i-abrasive abrasive (Al2O3) ibe yi-aluminates ethambileyo, yeglobular calcium. Lo ngumahluko phakathi kwentsimbi ethwalayo engaphumeleliyo ngaphambi kwexesha kunye neyokuhlala. Ndizibonile iibhetshi apho batsibe khona kunyango lwe-Ca ukonga iirandi ezimbalwa, kuphela ukuba nomsebenzi wokuzoba ngocingo ukhathazwa kukuqhawuka – ukonga okuxabisa kakhulu.

I-alloy's form factor ibaluleke ngaphezu kokuba abantu becinga. Sasidla ngokusebenzisa izigaqa ezininzi, kodwa ukutshintshela kwi-cored wire - apho i i-calcium ephantsi umgubo upakishwe kwisingxobo sentsimbi – ibiyinto etshintsha umdlalo. Ubunzulu benaliti kunye nesivuno siphucuke kakhulu. Ufumana i-calcium eyongezelelekileyo ekunyibilikeni apho ifuneka khona, ingatshi kumphezulu. Ababoneleli bayathanda I-Inner Mongolia i-Xinxin Silicon Industry Co.,Ltd ibenemigca epheleleyo yezi mveliso, ekuxelela ukuba le ndlela yonikezelo ibe sembindini kangakanani na. Uluhlu lwazo, ukusuka kwi-ferrosilicon eqhelekileyo ukuya kwiingcingo ezikhethekileyo, luqaqambisa intshukumo yeshishini ekuchanekeni.

Emva koko kukho ibali lesulfure. Ewe, yi i-desulfurizer, kodwa ukusebenza kwayo kuhambelana ngokuqinileyo kunye nesiseko se-slag kunye nobushushu. Kwi-slag esisiseko, ukusebenza okuphezulu kweqondo lokushisa, ukuxhamla kwe-calcium yesulfure kukhanya ngokwenene, yenze i-CaS engena kwi-slag. Kodwa ukuba iimeko zakho zivaliwe, awufumani i-desulfurization enzulu oyihlawuleleyo. Sisixhobo, hayi induku yomlingo.

UQhagamshelwano lokuCasa: Ukulawulwa kwe-Inoculation kunye ne-Morphology

Kulapho i-calcium ephantsi amanyathelo aphuma kwivenkile yentsimbi ukuya kwindawo efumaneka kuyo. Kwimveliso ye-iron ductile, iyona nxalenye ephambili kwi-nodulizing alloys, ehlala i-magnesium kunye nomhlaba onqabileyo. I-calcium inceda ukugoba ukunyibilika, ukukhuthaza ukwakheka kwegraphite engqukuva. Kodwa sisenzo sokulinganisa. Incinci kakhulu, kwaye awufumani isiphumo esipheleleyo se-nodularizing; kakhulu, kwaye unokwandisa ukubunjwa kwenkunkuma. Ndikhumbula isilingo kunye ne-calcium inoculant ephezulu eyakhokelela kwi-slag buildup ebuhlungu kwi-ladle kunye ne-crusty surfaces kwi-castings. Siyicofe kwakhona, sidibanisa ibakala elahlukileyo, kwaye ingxaki yalungiswa.

I-silicon barium calcium alloys ekhankanywe ngabavelisi abafana ne-Xinxin Silicon ngumzekelo oqhelekileyo wesi sicelo. I-barium kuthiwa yokwandisa umphumo we-inoculation, ukulwa kuphelile. Ingaba iindleko ezongezelelweyo ze-barium zifanelekile kuxhomekeke ngokupheleleyo kumaxesha akho okubamba kunye nobukhulu becandelo lokuphosa. Kwicandelo elincinci, ukuphosa ngokukhawuleza, umgangatho i-silicon ye-calcium inokwenza kakuhle. Olu luhlobo lokugweba olusebenzayo, oluqonda indleko olwahlula i-spec eluncedo kwi-engineered ngaphezulu.

Ngaphandle kwesinyithi, kwi-aluminium casting, izongezo ze-calcium ezihlambulukileyo zisetyenziselwa ukuguqula i-silicon morphology kwi-Al-Si alloys, ukuphucula iimpawu zomatshini. Lirhamncwa elahlukileyo ngokupheleleyo - iimfuno zococeko zigqithisile - kodwa zibonisa ukuguquguquka kwezinto kuyo yonke isinyithi.

Ukwahlula kunye nokuNgaphaya: Iindima ezaziwayo kancinci

Ngelixa ingengomsebenzi wayo ophambili, i-calcium yinto edibanisa ngabom kwezinye iintsimbi, njengamabakala athile asimahla omatshini. Apha, i-calcium yenza ii-oxides ezintsonkothileyo kunye ne-sulfide (ezifana ne-CaO-Al2O3 okanye i-CaS) ezisebenza njengomaleko wokuthambisa kwi-tool-chip interface ngexesha lomatshini. Sisiphumo esichuliweyo, kodwa kwimisebenzi yomatshini yomthamo omkhulu, ubomi besixhobo esandisiweyo kunye nokuphuculwa komphezulu wokugqiba ukuhlawula ukongezwa kwealloyi amaxesha amaninzi ngaphezulu.

Kukho nendima yayo ekucoceni intsimbi. Uhlengahlengiso lokuquka endilukhankanye ngaphambili lumalunga nococeko. Ukufakwa kweglowubhu akunakwenzeka ukuvala imilomo ye-tundish ngexesha lokusalwa okuqhubekayo. Inkqubo yokuphosa egudileyo ixabisa ubunzima bayo kwigolide, ukuphepha ukugqabhuka kunye nexesha lokuphumla. Ngoko, ngelixa sithetha i-deoxidizer kwaye i-desulfurizer, sithetha ngokwenene malunga nokuzinza kwenkqubo kunye nesivuno.

Ndikhe ndayibona isetyenziswa kwiibhetshi zovavanyo zokufumana i-titanium okanye njengenxalenye entsonkothileyo i-deoxidizer edibeneyo imixube ejolise kwiintsimbi ze-oxygen eziphantsi kakhulu kwizicelo ezibalulekileyo. Kule meko, yinxalenye ye-cocktail eyinkimbinkimbi, kungekhona i-agent emele.

Phantsi: Ukufumana, uMgangatho, kunye nokwahluka

Ayizizo zonke i-calcium ephantsi yenziwe ngokulinganayo. Umxholo we-Ca, umxholo we-Si, amanqanaba okungcola (ingakumbi i-Al kunye ne-C) - zonke ziguqula ukusebenza. Ibhetshi enobungakanani obungahambelaniyo iya kukunika isivuno esingahambelaniyo. Sakhe saba nomthengisi owayenemathiriyeli eyahluke kakhulu kubungakanani bentlama kangangokuba amaxabiso ethu okutya ayekuyo yonke indawo. Utshintshelwe kumvelisi oneempawu eziqinileyo zomzimba kunye neekhemikhali, kwaye iitshathi zethu zolawulo lwenkqubo zikhangeleka zisempilweni.

Apha kulapho iziseko zenkampani zibalulekile. Umvelisi oneseti epheleleyo yezixhobo zokuvavanya ngokuchanekileyo, njengoko kuphawuliwe kwinkcazo yeXinxin Silicon, akaziqhayisi nje. Kuthetha ukuba banako (okanye kufuneka babe nakho) ukubonelela ngohlalutyo oluqinisekisiweyo, ukuhambelana kwe-lot-to-lot, kunye nokulandeleka. Kwi-steelmaker, ukuthembeka oko kudla kubaluleke kakhulu kunexabiso eliphantsi kancinci ngetoni nganye. Ubushushu obungaphumeleliyo ngenxa yezongezo ze-off-spec yindleko eyintlekele.

Indawo yemveliso nayo ibalulekile. I-Mongolia yangaphakathi yi-hub ye-ferrosilicon kunye ne-alloys ehambelanayo ngenxa yamandla kunye nokufikelela kwezinto eziluhlaza. Ukukhangela ukusuka apho, kubadlali abasele bemile, kuhlala kuthetha ikhonkco lokubonelela elizinzileyo. Kodwa kusafuneka uqinisekise. Inkqubo yolawulo egqibeleleyo ephepheni ayiqinisekisi imathiriyeli egqibeleleyo kumgangatho wevenkile yakho. Hlala uphicotha, soloko uvavanya imithwalo engenayo.

Ukusonga: Sisixhobo seNkqubo, hayi iNtengiso

Ngoko, yintoni i-calcium ephantsi isetyenziselwe? Sisixhobo sesinyithi senkqubo esebenzayo. Ukusetyenziswa kwayo okuphambili kukucokisa insimbi ye-liquid kunye nentsimbi, kodwa ixabiso layo liphelele kwiinkcukacha zesicelo. Imalunga nobunjineli bokubandakanywa, ukuthembeka kwenkqubo, kunye nokusebenza kwemveliso yokugqibela.

Ukuyicinga njengento eyongezelelweyo elula iyona mpazamo enkulu. Kufuneka uqonde iiparameters zenkqubo yakho, isiseko sakho sekhemistri, kunye neenjongo zakho zokugqibela zemveliso ukukhetha ifom efanelekileyo kunye nebakala. Ngamanye amaxesha, i-alloy ye-calcium ephantsi, ephantsi, yenza umsebenzi. Ngamanye amaxesha, udinga ukucoceka okuphezulu, imveliso epakishwe ngokuchanekileyo.

Ekugqibeleni, yehla kule nto: sisitshixo esivula iziphumo ezithile zetsimbi. Kwaye njengaso nasiphi na isitshixo, sisebenza kuphela ukuba uyasazi ukuba yeyiphi itshixo onokuyivula kunye nendlela yokuyivula. Iimpawu ezivela kwinkampani efana I-Inner Mongolia i-Xinxin Silicon Industry Co.,Ltd ndikunike isitshixo esikrwada; ubugcisa bemetallurgist okanye injineli esisiseko isekujikeni.
