Izitini Zensimbi Egelezayo
Izitini zensimbi ezigelezayobhekisela ezitini ezingenalutho ezicwebezelayo ezibekwe emifantwini yepuleti eliphansi le-ingot casting ukuxhuma izitini zensimbi ezigelezayo kanye nesikhunta se-ingot, esaziwa kakhulu ngokuthi isitini esigijimayo. Sisetshenziswa kakhulu ukunciphisa ukumelana nokugeleza kwensimbi encibilikisiwe nokuvimbela ukuvuza kwensimbi. Izici eziyinhloko zifaka phakathi ukumelana nokucindezela kokushisa okuphezulu, ukumelana nokuguguleka, ukugeleza okuhle, ukufakwa okulula kanye nokumelana okuhle nomlilo.
1. Ukuhlukaniswa ngokwezinto ezibonakalayo:
(1) Ubumba:Lolu uhlobo oluyisisekelo kakhulu lwesitini sensimbi egelezayo, esenziwe ngobumba oluvamile. Nakuba intengo iphansi, ayinamandla okumelana nomlilo kanye nempilo yesevisi, futhi ifanelekela ezinye izigayo zensimbi ezincane noma izimo zokusetshenziswa kwesikhashana.
(2) I-aluminium ephezulu:Lesi sitini sensimbi esigelezayo siqukethe okuqukethwe okuphezulu kwe-aluminium, sinokumelana okuhle kakhulu nomlilo, futhi singahlala sizinzile ezindaweni ezinokushisa okuphezulu. Sivame ukusetshenziswa emabhizinisini amakhulu ensimbi, ikakhulukazi ezinqubweni zokwenza insimbi ezidinga ukumelana nokushisa okuphezulu isikhathi eside.
(3)Iziningi:Amakristalu anombala onjengenaliti abonisa isakhiwo esihlanganisa inethiwekhi, esingavimbela ngempumelelo ukuguguleka kwensimbi encibilikisiwe. Njengamanje yiwona oyinhloko.
2. Ukuhlukaniswa ngokwemisebenzi:
(1) Izitini Eziphakathi
Isetshenziswa endaweni eyinhloko yokugeleza kwensimbi encibilikisiwe, isekela indlela yokugeleza futhi idinga ukuphakama okuphezulu
ukuphikiswa kanye nokumelana nokuguguleka.
(2) Izitini Zokuhlukanisa Insimbi
Kusetshenziswa ukuphambukisa insimbi encibilikisiwe iye ezikhumbeni ezahlukene. Imininingwane evamile ifaka phakathi imigodi emibili, emithathu, kanye nemine, kuye ngezidingo zenqubo.
(3) Izitini Zomsila
Njengoba zitholakala ekugcineni kohlelo lokugeleza kwensimbi, zimelana nokushaywa yinsimbi encibilikisiwe kanye namazinga okushisa aphezulu futhi zidinga ukumelana nokuqhekeka.
1. Ukumelana okuphezulu kokushisa okuphezulu
Ziyakwazi ukubekezelela izinga lokushisa eliphakeme kakhulu lensimbi encibilikisiwe engu-1500–1700℃ isikhathi eside. Izitini ezibunjiwe ezisekelwe ku-mullite, isibonelo, zinamandla okubamba angaphezulu kuka-1780℃, okwenza zifanelekele izimo zokubunjwa ezishisa kakhulu.
2. Ukumelana nokuguguleka okunamandla
Njengoba inesakhiwo esiqinile nesiqinile, ukubumba izitini kungamelana ngempumelelo nokukhuhla okubangelwa ukugeleza kwensimbi encibilikisiwe ngesivinini esikhulu, kunciphisa ukuguguleka ngesikhathi sokusebenza.
3. Ukumelana okuhle kakhulu nokugqwala
Zingamelana nokuguguleka kwamakhemikhali okuvela ensimbini encibilikisiwe kanye nama-slag ahlukahlukene. Ukwakheka kwezinto ezahlukene kulungiselelwa izimo ezithile zokusebenza.
4. Ukumelana okuhle nokushaqeka kokushisa
Zingakwazi ukubekezelela ukuguquguquka kwezinga lokushisa okusheshayo ngesikhathi senqubo yokubumba ngaphandle kokuqhekeka noma ukuqhekeka.
5. Ukungcola okuphansi kwensimbi encibilikisiwe
Isakhiwo sezinto eziqinile sinciphisa ukuxebuka nokuchitheka kwezinhlayiya, sigwema ukufakwa kokungcola ensimbini encibilikisiwe futhi siqinisekise ubumsulwa nekhwalithi yemikhiqizo yensimbi yokugcina.
6. Ukunemba okunembile kobukhulu
Zineziteshi zangaphakathi ezibushelelezi, izimo zangaphandle ezijwayelekile, kanye nokubekezelelana okuqinile. Lokhu kuqinisekisa ukuhlangana okungenamthungo ngesikhathi sokufakwa, kunciphisa ukumelana nokugeleza kwensimbi encibilikisiwe, futhi kuvimbela izingozi zokuvuza kwensimbi.

Izitini zensimbi ezigelezayozisetshenziswa kakhulu enqubweni yokubumba engezansi, zisebenza njengomsele wensimbi encibilikisiwe ukuze igeleze isuka eladleni iye ezikhumbeni ze-ingot, iqinisekisa ukusatshalaliswa okubushelelezi kwensimbi encibilikisiwe kusikhumbeni ngasinye se-ingot.
Umsebenzi Oyinhloko
Izitini zensimbi ezigelezayo, ezidlula ngaphakathi kwazo okungenalutho, ziqinisekisa ukugeleza kwensimbi encibilikisiwe ngendlela eqondile, ziyivimbela ukuthi ingathinti ngqo isikhunta se-ingot futhi inciphise ukwehluleka kwesakhiwo okubangelwa ukushisa ngokweqile kwendawo. Ngaphezu kwalokho, izakhiwo zazo zokungaguquki zivumela ukuthi zikwazi ukumelana nomthelela ongokwenyama kanye nokusabela kwamakhemikhali kwensimbi encibilikisiwe eshisa kakhulu, zivimbele ukungcola ukuthi kungangeni ensimbini futhi kuthinte ikhwalithi yayo.
I-Shandong Robert New Material Co., Ltd.itholakala eDolobheni laseZibo, eSifundazweni saseShandong, eShayina, okuyisisekelo sokukhiqiza izinto ezingaphili.
