Izingxenye eziyinhloko zezinto eziphikisayo ezifana izitini eziphefumula, izitini ze-nozzle block, nezinsimbi

Izinto eziphikisayo zisetshenziswa kabanzi ku-metallurgy, ubuchwepheshe bamakhemikhali, i-petroleum kanye ne-petrochemical, ukukhiqizwa kwemishini, ukucutshungulwa kwamandla kanye neminye imikhakha yezimboni, lapho inani elikhulu kakhulu lisetshenziswa embonini ye-metallurgical. Kumaledi ensimbi nasezithandweni zokucwengisisa embonini yokwenza insimbi, izinto eziphikisayo ezivame ukusetshenziswa abakhiqizi bokwenza insimbi zihlanganisa izitini eziphefumulayo, izitini ze-nozzle block, izembozo zomlilo kagesi, izinto ezisansimbi, isihlabathi esikhipha amanzi, izitini zekhabhoni ye-magnesia, njll. Lezi zinto eziphikisayo zihlukile, futhi izingxenye eziyinhloko kanye nezingxenye ezengeziwe zihluke kakhulu. Kusukela ekuhlaziyweni kwamakhemikhali, izinto eziphikisayo zenziwe ngamaminerali, njenge-corundum, i-mullite, i-magnesia, njll. Izingxenye eziyinhloko zazo ziyi-alumina ne-magnesia.

Ngokuqondene nengxenye eyinhloko yezinto eziphikisayo, yingxenye ye-matrix eyenza impahla ye-refractory, isisekelo sezimpawu zezinto eziphikisayo, futhi inquma ngokuqondile izakhiwo zemikhiqizo ye-refractory. Isibonelo, izitini eziphefumulayo zidinga ukwenziwa nge-ore yekhwalithi ephezulu, bese zenziwe ngezinqubo eziqinile nezinengqondo, ukuze kuqinisekiswe ukuthi isikhathi sokuphila kwezitini eziphefumulayo ezisetshenziswa abakhiqizi bensimbi bungahlangabezana nezidingo. Izingxenye eziyinhloko zezinto eziphikisayo zingaba ama-oxides (i-aluminium oxide, i-magnesium oxide, njll.), noma izakhi noma ama-non-oxide compounds (i-carbon, i-silicon carbide, njll.).

Ngokwemvelo yezingxenye eziyinhloko, izinto eziphikisayo zingahlukaniswa ngezigaba ezintathu: i-acidic, neutral, ne-alkaline. Izinto eziphikisayo ezine-Acidic ikakhulukazi izinto eziqukethe ama-asidi e-acidic njenge-silicon oxide. Ingxenye eyinhloko i-asilicic acid noma i-aluminium silicate, ezokhiqiza usawoti ngaphansi kwesenzo sokushisa okuphezulu kanye ne-alkali. Izingxenye zamakhemikhali eziyinhloko ze-alkaline refractories i-magnesium oxide, i-calcium oxide, njll. Imikhiqizo evamile ephikisayo ihlanganisa isihlabathi sokudonsa amanzi kanye namaslayidi e-ladle. Ama-refractories angathathi hlangothi ayi-carbonaceous kanye ne-chromium refractories. Ukwengeza, ama-refractories e-aluminium ephezulu (okuqukethwe kwe-alumina okukhulu kuno-45%) kuyizici zokuphikisa ezingathathi hlangothi ezivame ukuba ne-asidi, kuyilapho i-chromium refractories ijwayele ukuba ne-alkaline kakhulu. Okwezinto eziphikisayo ezingathathi hlangothi, izinto ezivamile zokuphikisa i-alumina ephezulu zifaka izitini eziphefumulayo, izitini ze-nozzle block, namakhava kagesi kagesi.

Inkampani yethu ineminyaka engu-18 yocwaningo nokuthuthukiswa, ukukhiqizwa nokudayiswa kwezinto eziphikisayo ezifana nezitini eziphefumulayo, izitini ze-nozzle block, izinsimbi, namafomula anelungelo lobunikazi, imiklamo eyingqayizivele, nokuqaliswa okuqinile nokujwayelekile kwenqubo ngayinye, ukuze abakhiqizi bensimbi bakwazi ukuzisebenzisa. ngokuthula kwengqondo nenduduzo.
