Emisebenzini yezimboni eshisa kakhulu, izinto eziqinile zokungaguquguquki zibalulekile ekuqineni nasekuphepheni kwemishini.I-castable ephezulu ye-alumina refractory—enokuqukethwe kwe-alumina okungu-45%–90%—ivelele njengokukhetha okuphezulu, ngenxa yokusebenza kwayo okuhle kakhulu ezindaweni ezishisayo ezinzima. Ngezansi kunencazelo emfushane yezimpawu zayo ezibalulekile kanye nokusetshenziswa kwayo.
1. Izakhiwo Eziyinhloko Ze-High-Alumina Refractory Castable
1.1 Ukumelana Okuqinile Nokushisa Okuphezulu
Igcina ubuqotho besakhiwo ku-1600–1800℃ isikhathi eside (ngokumelana nesikhathi esifushane neziqongo eziphakeme), isebenza kangcono kunezinye izindlela ze-alumina eziphansi. Emisebenzini yamahora angu-24/7 njengokwenza insimbi noma ukukhiqizwa kwesimende, lokhu kunciphisa ukuvalwa kokugcinwa futhi kwandise impilo yemishini.
1.2 Amandla Aphezulu Okusebenza Kwemishini
Njengoba inamandla okucindezela angu-60–100 MPa ekushiseni kwegumbi, iphatha isisindo nezinto ezinkulu ngaphandle kokuqhekeka. Okubaluleke kakhulu, igcina amandla ngaphansi kokushisa, imelana nokushaqeka kokushisa—ilungele izitofu ezincibilikisa ingilazi lapho amazinga okushisa eshintshashintsha khona, okunciphisa ukwehluleka okubizayo kwendwangu.
1.3 Ukumelana Nokuguguleka Nokukhuhla
Isakhiwo sayo esiminyene simelana nokuguguleka kwamakhemikhali (isb., i-slag encibilikisiwe, amagesi ane-asidi) kanye nokuguguleka ngokomzimba. Kuma-converter ensimbi, imelana nensimbi encibilikisiwe egeleza ngokushesha; kuma-incinerator emfucuza, ivikela amagesi ane-asidi e-flue, yehlisa izidingo zokulungisa kanye nezindleko.
1.4 Ukufakwa Okulula Nokuguquguquka
Njengempuphu enkulu, ixubana namanzi/i-binder ibe yi-slurry ethululekayo, ifake ezimweni ezingajwayelekile (isb., amakamelo esithando esenziwe ngokwezifiso) izitini ezenziwe ngaphambilini ezingenakukwazi ukuhambisana nazo. Idala ulwelwesi olungenamthungo lwe-monolithic, isusa "ukuvuza komlilo" futhi ifanelane nokwakhiwa okusha noma ukulungiswa kabusha.
2. Izicelo Eziyinhloko Zezimboni
2.1 Insimbi kanye ne-Metallurgy
Isetshenziswa ezindongeni zesithando somlilo (i-bosh/hearth, >1700℃), ezindongeni zesithando somlilo sikagesi (EAF), kanye nezitsha—imelana nokuguguleka kwensimbi encibilikisiwe kanye nokulahlekelwa ukushisa. Iphinde ifake izithando zomlilo ezivuselelayo ukuze kuncibilikiswe i-aluminium/copper.
2.2 Usimende Nengilazi
Ilungele izindawo ezishiswayo zesimende (1450–1600℃) kanye nezingxenye ze-preheater, ezimelana nokuguguleka kwe-clinker. Ekwenzeni ingilazi, ivala amathangi ancibilikisayo (1500℃), imelana nokugqwala kwengilazi encibilikisiwe.
2.3 Ukwelashwa Kwamandla Nokuchitha Imfucuza
Imigqa ye-boiler eqhutshwa ngamalahle (emelana nomlotha wezimpukane) kanye namakamelo okushisa imfucuza (emelana nokushisa okungu-1200℃ kanye nemikhiqizo engaba ne-asidi), iqinisekisa ukusebenza okuphephile, okuphansi kwesikhathi sokungasebenzi.
2.4 Amakhemikhali Kaphethroli Namakhemikhali
Ifaka ama-crackers anomusi (1600℃, ukuze kukhiqizwe i-ethylene) kanye nama-oven okusa amaminerali (isb., umanyolo), amelana nomhwamuko we-hydrocarbon kanye namakhemikhali agqwalisayo.
3. Kungani Uyikhetha?
Impilo Ende:Ihlala isikhathi eside izikhathi ezingu-2-3 kunezinto zobumba eziphonswayo, okunciphisa ukushintshwa.
Kuqiza kahle:Izindleko zokuqala eziphezulu zincishiswa ukulungiswa okuphansi kanye nokuphila isikhathi eside.
Okungenziwa ngezifiso:Okuqukethwe kwe-alumina (45%–90%) kanye nezithasiselo (isb., i-silicon carbide) kuhambisana namaphrojekthi.
4. Ubambisene Nomhlinzeki Othembekile
Funa abaphakeli abasebenzisa izinto ezihlanzekile kakhulu, abanikeza amafomula enziwe ngokwezifiso, isiqondiso sobuchwepheshe, kanye nokulethwa ngesikhathi. Kungakhathaliseki ukuthi uthuthukisa isithando sensimbi noma ukuvala isithando sikasimende, i-castable e-alumina refractory ephezulu inikeza ukuthembeka—xhumana nathi namuhla ukuze uthole isilinganiso.
