I-Corundum Castable

Impahla eluhlaza ye-corundum castable ihlanganiswe i-corundum emhlophe, i-corundum ehlanganisiwe noma i-brown corundum. Kungakhathaliseki ukuthi hlobo luni lwezinto zokusetshenziswa ezisetshenziswa njenge-aggregate, izinhlayiya ezinobukhulu obuhlukene bezinhlayiyana kufanele zixutshwe ngokulingana, futhi izinhlayiya eziqinile ze-corundum, izinhlayiya eziphakathi nendawo kanye nempushana kufanele zibe namafomula afanele, bese zihlanganiswa nezithasiselo ze-Qihe (i-silica micropowder, i-water reducer kanye ne-powder). i-fiber engaqhumi), kufanele yengezwe ezintweni ezingavuthiwe futhi ifutheke ngokugcwele.

Umsebenzi Womkhiqizo

Uma kuqhathaniswa ne-alumina ephezulu ekwazi ukuphonswa kanye ne-mullite castable, i-corundum castable inamandla aphakeme wemishini kanye nokumelana nokugqoka, kodwa ukumelana nokushaqeka kwayo okushisayo akukuhle njenge-mullite castable. Ukwengeza inani elithile le-mullite ezintweni ezingavuthiwe kungathuthukisa ukumelana nokushaqeka okushisayo kwe-corundum castable. I-Corundum castable inamandla acindezelayo aphezulu kanye nokuzinza okuhle kwesakhiwo. Umthamo omkhulu, i-corundum castable casting lining inokumelana nokugqwala okuhle kwe-slag, ukumelana nokuqina, ukumelana nokugqoka okuphezulu kanye nokumelana okuqinile nezinhlayiya eziqinile, impushana kanye nokuguguleka kwegesi lokushisa okuphezulu.

Isicelo somkhiqizo

I-Ferrosilicon furnace yisithando somlilo esisebenza ngogesi sezimboni esisebenzisa amandla amaningi futhi siwuhlobo lwesithando somlilo se-arc esingaphansi kwamanzi. Isithando somlilo se-Ferrosilicon sihlanganisa igobolondo lesithando somlilo, ikhava yesithando somlilo, ulayini lwesithando somlilo, inethi emfushane, isistimu yokupholisa amanzi, isistimu yokukhipha intuthu, isistimu yokukhipha uthuli, igobolondo le-electrode, ukukhishwa kwengcindezi ye-electrode kanye nesistimu yokuphakamisa, isistimu yokulayisha nokukhipha, isilawuli, idivayisi yokusha, i-hydraulic. uhlelo, i-transformer Kanye nemishini kagesi ehlukahlukene, njll., ukusetshenziswa kwezinto eziphikisayo nakho kufuna kakhulu.

Ngo-2006, imboni yethu yasungulwa e-Yuzhou, isisekelo sezinto ezingavuthiwe. I-bauxite ore ephezulu iyingxube ye-colloidal ehlukaniswe kahle eyakhiwa ama-aluminium hydroxides kanye nezilinganiso ezihlukahlukene. I-high-alumina bauxite embonini ye-refractory ngokuvamile ibhekisela ku-bauxite ore enokuqukethwe okubaliwe kwe-Al₂O₃ okukhulu kuno-48% nokuqukethwe okuphansi kwe-Fe₂O₃.
