Izitini Zensimbi Ezigelezayo
Incazelo Yomkhiqizo
Izitini zensimbi ezigelezayobhekisela ezitini eziphikisayo ezingenalutho ezibekwe emiseleni yepuleti elingaphansi le-ingot casting ukuze kuxhunywe izitini zensimbi egelezayo kanye nesikhunta se-ingot, esivame ukwaziwa ngokuthi isitini se-runner. Ikakhulu isetshenziselwa ukunciphisa ukumelana nokugeleza kwensimbi encibilikisiwe nokuvimbela ukuvuza kwensimbi. Izici eziyinhloko zihlanganisa ukumelana nokucindezela kokushisa okuphezulu, ukumelana nokugqoka, uketshezi oluhle, ukufakwa kalula nokumelana nomlilo okuhle.
1. Ukuhlukaniswa ngempahla:
(1)Ubumba:Lona uhlobo oluyisisekelo kakhulu lwezitini zensimbi ezigelezayo, ezenziwe ngobumba obujwayelekile. Nakuba intengo iphansi, impofu uma kuqhathaniswa ekumelana nomlilo nempilo yesevisi, futhi ifanele izigayo zensimbi ezincane noma izimo zokusetshenziswa kwesikhashana.
(2)I-aluminium ephezulu:Lesi sitini sensimbi esigelezayo siqukethe okuqukethwe okuphezulu kwe-aluminium, sinokumelana nomlilo okuhle kakhulu, futhi singahlala sizinzile ezindaweni zokushisa eziphezulu. Ivamise ukusetshenziswa emabhizinisini amakhulu ensimbi, ikakhulukazi ezinqubweni zokwenza insimbi ezidinga ukumelana namazinga okushisa aphezulu isikhathi eside. .
(3)Mullite:Amakristalu angaphezulu amise okwezinaliti aveza isakhiwo sesiphambano senethiwekhi, esingavimbela ngempumelelo ukuguguleka ngensimbi encibilikisiwe. Njengamanje iwumsebenzi ojwayelekile.
2. Ukuhlelwa ngokokusebenza:
(1)Izitini ezimaphakathi
Isetshenziswa endaweni ewumgogodla wokugeleza kwensimbi encibilikisiwe, isekela indlela yokugeleza futhi idinga ukuphakama
refractoriness kanye nokumelana nokuguguleka.
(2) Izitini Zesihlukanisi Sensimbi
Isetshenziselwa ukuphambukisa insimbi encibilikisiwe esikhunjeni esihlukene. Ukucaciswa okujwayelekile kufaka phakathi izimbobo eziphindwe kabili, ezintathu, nezine, kuye ngezidingo zenqubo.
(3)Izitini Zomsila
Akhiwe ekupheleni kwesistimu yokugeleza kwensimbi, amelana nomthelela wensimbi encibilikisiwe namazinga okushisa aphezulu futhi adinga ukumelana nokuphuka.

Isicelo
Izitini zensimbi ezigelezayoasetshenziswa ngokuyinhloko enqubweni yokubunjwa yaphansi, esebenza njengomzila wensimbi encibilikisiwe ukuze igeleze isuka ku-ladle iye esikhunjeni se-ingot, iqinisekisa ukusatshalaliswa okubushelelezi kwensimbi encibilikisiwe ekubunjweni kwengot ngayinye.
Umsebenzi oyinhloko
Izitini zensimbi ezigelezayo, ngaphakathi kwazo okungenalutho, ziqinisekisa ukugeleza okuqondile kwensimbi encibilikisiwe, ukuyivimbela ukuthi ingabambi ngokuqondile isikhunta se-ingot kanye nokunciphisa ukwehluleka kwesakhiwo okubangelwa ukushisa okweqile kwendawo. Ngaphezu kwalokho, izakhiwo zabo eziphikisayo zibavumela ukuba babhekane nomthelela womzimba kanye nokusabela kwamakhemikhali ensimbi encibilikisiwe yezinga lokushisa eliphezulu, ukuvimbela ukungcola ekungeneni kwensimbi futhi kuthinte ikhwalithi yayo.
Iphrofayela Yenkampani
Inkampani Shandong Robert New Material Co., Ltd.itholakala eZibo City, eSifundazweni saseShandong, eChina, okuyindawo yokukhiqiza impahla ephikisayo. Siyinkampani yesimanje ehlanganisa ucwaningo nentuthuko, ukukhiqiza, ukuthengisa, ukwakhiwa kweziko nokwakha, ubuchwepheshe, kanye nezinto ezikhiqizayo zokuthumela ngaphandle.
