Izitini ze-Silica Refractory
Ulwazi Lomkhiqizo
Izitini ze-silica eziphikisayoiyinto ephikisayo ene-asidi ene-silicon dioxide njengengxenye eyinhloko, enokuhlanzeka okuphezulu kanye nezakhiwo ezinhle zokuphikisa. Ingxenye yayo eyinhloko yi-silicon dioxide (SiO2), okuqukethwe kwayo okuvame ukuba ngaphezu kwama-93%, kanti okuqukethwe yi-silicon dioxide kwezitini ze-silica ezisezingeni eliphezulu kungafinyelela cishe ku-96%. Inqubo yokukhiqiza izitini ze-silica ihlanganisa ukulungiswa kwezinto zokusetshenziswa, ukuxuba kanye nokuhlanganiswa, ukubumba, ukomisa, ukudubula, ukuhlola kanye nokupakisha. Phakathi kwazo, ukulawulwa kokushisa ngesikhathi senqubo yokudubula kubalulekile futhi kudinga ukulawulwa kokushisa okunembile ukuqinisekisa ikhwalithi.
Izici
Ukumelana okunamandla nokuguguleka kwe-asidi slag:Izitini ze-silica zinamandla okumelana nezinto ezibolayo njenge-asidi slag kanye nensimbi encibilikisiwe, okuqinisekisa ukuthi zihlala isikhathi eside.
Izinga lokushisa eliphakeme lokuthambisa:Izinga lokushisa lokuthambisa umthwalo wezitini ze-silica liphezulu njengo-1640-1670℃, futhi ivolumu izinzile uma isetshenziswa isikhathi eside ekushiseni okuphezulu.
Ukuqina kwevolumu okuhle:Uma izinga lokushisa liphezulu lika-1600℃, izitini ze-silica zingagcina isakhiwo sizinzile futhi zibe nesivinini esiphansi sokukhukhuleka.
Ukuqina kwamakhemikhali okuphezulu:Izitini ze-silica zinokumelana okuhle nama-oxide afana ne-Al2O3, i-FeO, i-Fe2O3, kodwa azimelani kahle ne-alkaline slag (njenge-CaO, i-K2O, i-Na2O).

Isicelo
1. Izitini ze-silica zisetshenziswa kakhulu odongeni lokuhlukanisa lwegumbi lokufaka i-carbonization kanye negumbi lokushiswa kwe-oven ye-coke, igumbi lokuvuselela kabusha kanye negumbi le-sediment lesithando esivulekile sensimbi, isithando esijwayelekile sokushisa, izinto eziphikisayo zesithando sokuncibilikisa ingilazi kanye nesithando sesithando se-ceramic, kanye nezinye izingxenye ze-oven.
Iphrofayela Yenkampani
I-Shandong Robert New Material Co., Ltd.itholakala eDolobheni laseZibo, eSifundazweni saseShandong, eShayina, okuyisisekelo sokukhiqiza izinto ezingaphili. Siyibhizinisi lesimanje elihlanganisa ucwaningo nentuthuko, ukukhiqiza, ukuthengisa, ukuklama nokwakha ihhavini, ubuchwepheshe, kanye nezinto ezingaphili ngaphandle. Sinemishini ephelele, ubuchwepheshe obuthuthukisiwe, amandla aqinile obuchwepheshe, ikhwalithi yomkhiqizo enhle kakhulu, kanye nedumela elihle.Ifektri yethu ihlanganisa amahektha angaphezu kuka-200 kanti umkhiqizo waminyaka yonke wezinto ezijikijelayo ezimise okwesibuko ungaba amathani angu-30000 kanti izinto ezijikijelayo ezingamise okwesibuko zingamathani angu-12000.
Imikhiqizo kaRobert isetshenziswa kabanzi kuma-oven ashisa kakhulu njengezinsimbi ezingenayo insimbi, insimbi, izinto zokwakha kanye nokwakhiwa, amakhemikhali, amandla kagesi, ukushiswa kwemfucuza, kanye nokwelashwa kwemfucuza eyingozi. Zisetshenziswa futhi ezinhlelweni zensimbi nezensimbi ezifana nama-ladle, i-EAF, ama-oven e-blast, ama-converter, ama-oven e-coke, ama-oven e-hot blast; ama-oven e-metallurgical angenayo insimbi njengama-reverberator, ama-oven e-reduction, ama-oven e-blast, kanye nama-oven ajikelezayo; ama-oven ezimboni ezinto zokwakha njenge-oven yengilazi, ama-oven esimende, kanye nama-oven e-ceramic; amanye ama-oven afana nama-boiler, ama-incinerator emfucuza, ama-oven e-roasting, athole imiphumela emihle ekusebenziseni. Imikhiqizo yethu ithunyelwa eNingizimu-mpumalanga ye-Asia, e-Asia Ephakathi, eMpumalanga Ephakathi, e-Afrika, eYurophu, eMelika nakwamanye amazwe, futhi isungule isisekelo esihle sokubambisana namabhizinisi amaningi ensimbi adumile.
