Akukona ukumiselela okuqondile kodwa kunalokho kungumphelelisi. I-Aluminium iyi-deoxidizer enamandla futhi ivamise ukungezwa kuqala. I-Ferro calcium silicon isetshenziselwa ukuguqula i-alumina inclusions eyenziwe yi-aluminium futhi isuse isulfure, i-aluminium engakwazi ukuyenza ngempumelelo.

Ngabe usayizi wezinhlayiyana ulithinta kanjani izinga lokuthola kabusha?
Usayizi wezinhlayiya ubalulekile. Uma izinhlayiya zincane kakhulu, zingase zibe oxidize ku-slag noma zilahleke ezinhlelweni zokuqoqa uthuli. Uma zinkulu kakhulu, zingase zingancibiliki ngokuphelele ngaphambi kokuba insimbi iqine noma iphonswe. Ibanga losayizi elilungile liqinisekisa ukuthi ingxubevange ifinyelela ekujuleni kokuncibilika futhi incibilika kahle.

Ingabe i-ferro calcium silicon iphephile ukuphatha?
Njengama-ferroalloy amaningi, ikhiqiza uthuli olungacasula isimiso sokuphefumula namehlo. Ingase futhi isabele ngomswakama ukuze ikhiphe amagesi avuthayo. I-PPE efanele, ukungena komoya, kanye nesitoreji esomile kuyimpoqo ukuze kuphathwe ngendlela ephephile.

Imaphi amamaki ensimbi azuza kakhulu kule alloy?
Izinsimbi ze-high-strength low-alloy (HSLA), izinsimbi zamapayipi, izinsimbi zamashidi ezimoto, nezinsimbi zikaloliwe kuzuza kakhulu. Noma yiliphi ibanga elidinga isulfure ephansi, ukuqina okuphezulu, kanye nekhwalithi ephezulu kakhulu izobona ukuthuthuka okubalulekile ekwelashweni kwe-calcium.

Isiphetho kanye Nezincomo Zochwepheshe

I-Ferro calcium silicon imile njengetshe lesisekelo ekuphishekeleni ikhwalithi ephezulu yensimbi nemikhiqizo yensimbi. Ikhono layo eliyingqayizivele lokuyikhipha ngasikhathi sinye i-deoxidize, i-desulfurize, futhi iguqule okufakiwe iyenza ingakwazi ukubuyiseleka ekuhambeni komsebenzi kwesimanje kwe-metallurgical. Ngokuguqula ukungcola okuyingozi kube amafomu alungile noma anenzuzo, kuthuthukisa ukusebenza kwemishini, ukuqina, kanye nokwenziwa kohlu olukhulu lwezingxenye zezimboni.

Kubenzi bensimbi kanye nabaqhubi be-Foundry, isihluthulelo sokuvula amandla aphelele ale alloy ilele ekulawuleni inqubo enembile. Ukuqonda ukusebenzisana phakathi kwezinga lokushisa, i-slag chemistry, kanye nesikhathi sokwengeza kubalulekile. Labo abakwazi kahle lokhu okuguquguqukayo bangafinyelela inhlanzeko yensimbi ephakeme kakhulu, banciphise izindleko zokukhiqiza, futhi balethe imikhiqizo ehlangabezana nezindinganiso zamazwe ngamazwe eziqinile.

Ubani okufanele asebenzise lo mkhiqizo? Le alloy ilungele abakhiqizi bezinsimbi ze-HSLA, izinto zamapayipi, amashidi ezimoto, nokusakazwa kobuqotho okuphezulu. Kubaluleke kakhulu ezindaweni ezifuna ukuthuthukisa ikhwalithi yomkhiqizo wazo ngaphandle kokutshala imali kungqalasizinda eyinkimbinkimbi yokujova ngocingo. Ukubambisana nomkhiqizi onolwazi olufana I-Inner Mongolia Xinxin Silicon Industry Co., Ltd. iqinisekisa ukufinyelela emikhiqizweni ephumelele ukuhlolwa okuqinile ngamahhovisi okuqondisa ekhwalithi nezobuchwepheshe, okusekelwe ukuzibophezela kobuqotho nokusebenza kahle kwezobuchwepheshe.

Izinyathelo Ezilandelayo: Uma ubheke ukuthuthukisa inqubo yakho yokwenza insimbi, hlola amazinga akho amanje okufakwa kanye nezinhloso zesibabule. Cabangela ukwenza izivivinyo nge-silicon yezinga le-ferro calcium ukuze unqume umthamo ophelele wezimo zakho ezithile ze-ladle. Ukusebenzisana nomphakeli ohlinzeka ngokuhlaziywa kwamakhemikhali okungaguquki, izinhlobonhlobo zemikhiqizo ehlukahlukene ehlanganisa ama-noduzer nezintambo ezinezintambo, nokusekelwa okuzinikele kwezobuchwepheshe kuzoqinisekisa impumelelo yakho ekukhiqizeni izinsimbi ezisezingeni lomhlaba.
