I-ladle lining

Izinto eziphikisayo zisetshenziswa ngaphansi kwezimo ezinzima ekukhiqizeni insimbi. Lokhu kuhlanganisa amazinga okushisa aphezulu kanye nokushaqeka kokushisa okubangelwa ukushintsha okungazelelwe kwezinga lokushisa. Lapho insimbi encibilikisiwe ijovwa isuka kusiguquli noma isithando somlilo se-arc sikagesi, izinga lokushisa ngezinye izikhathi lifinyelela amanani aphezulu kakhulu (>1700oc). Ngokuvamile, ngaphambi kokuba insimbi encibilikisiwe ijovwe, izinga lokushisa le-ladle lining layer liphakathi kuka-800-1200, okubangela ukucindezeleka kungqimba lokusebenza lwe-lining, okungase kubangele ungqimba olusebenzayo luhlakazeke.

Kuyaziwa ukuthi ikhono le-slag lokusabela emazingeni okushisa aphezulu libangela ukugqwala kwezinto eziphikisayo. Ukuguqulwa kokwakheka kwe-slag ikakhulukazi kuncike enqubweni yokuncibilikisa. Enqubweni ekhona yokuncibilikisa, ikakhulukazi ihlobene ne-alkaline slag, okungenzeka ukuthi isabele nge-corundum brick lining. Njengamanje, izitini ze-corundum periclase noma izitini ze-corundum spinel zivame ukusetshenziselwa ulwelwesi oluphelele lwe-ladle. Lapho ama-castables aphikisayo aqukethe i-spinel (10% -25%) asetshenziswa njenge-ladle linings, ikhono layo lokumelana nokulimala libaluleke kakhulu, ngoba isakhiwo sayo se-crystal sisiza ukubamba uchungechunge lwe-divalent noma i-trivalent cations (Fe2 + Wait). Ama-refractories aqukethe umgogodla ane-porosity ephansi kakhulu evulekile kanye nezakhiwo ezinhle kakhulu zemishini. Kodwa-ke, izinto zokwakha ezingezwe nge-magnesium oxide zithatha indawo eyengeziwe yalezi zinto, okokuqala ngenxa yezizathu zezindleko. Kodwa futhi ihlobene nokuphikiswa kwayo okuhle kokungena.

Abanye abacwaningi bakholelwa ukuthi lezi zenzo ezinhle zihlobene nokuminyana okuphezulu kwezinto ezibonakalayo kanye nendawo enkulu yeyunithi. Ukwakhiwa kwe-spinel kuhambisana nokuthuthukiswa kwama-pores microscopic ku-matrix ephikisayo. I-lime noma i-slag ingasabela nge-alumina futhi yakhe i-calcium hexaaluminate, ebangela ukwanda, okubangela ukuthi ezinye izimbotshana ezincane kakhulu zivaleke.

Ukushisa kwesendlalelo esihlala njalo se-ladle lining kuyisici esibalulekile esithinta ukusebenza kwayo. Kuphinde kube yisigaba esibaluleke kakhulu. Ngalesi sikhathi, noma yikuphi ukuphambuka kusuka ku-curve yokushisa efanelekile kuzobangela ukucindezeleka okukhulu ku-lining, ngezinye izikhathi Ukwenzeka kwesendlalelo esiqhumayo kuveza isenzo somshini, okuyisici esiyingozi kakhulu ngesikhathi sokusetshenziswa kwe-lining. Ukulandelana kokucubungula insimbi encibilikisiwe kanye nokuhamba ngebhayisikili okushisayo ngesikhathi sokusebenzisa i-ladle nakho kungabangela ukuthi ulwelwesi oluthile lube ntekenteke futhi luxebuke.
