Kukho iintlobo ezininziiyamashishiniaaluminiyammeltingfuurnace, ubukhulu becala isithando somlilo sokubonisa, isithando somlilo sokungeniswa, njl. njl., ukutshatyalaliswa kwesithando somlilo kukungena kolwelo lwe-aluminiyamu kunye nokucoca ulwelo lwayo ngezitena zodongwe, izitena eziphezulu ze-alumina eziphikisayo kunye ne-corundum mullite masonry yezitena, kodwa kunye ne-alumina ephezulu ye-refractory castables kunye i-refractory lining yeplastiki, ngenxa yokusetyenziswa kweemeko ezilungileyo, ubomi bomlilo bude.
Okokuqala, i-refractories ye-refractory yesithando somlilo, isithando somlilo sihlulwe sibe luhlobo olusisigxina kunye ne-tilting, usebenzisa igesi okanye ioli enzima njengamafutha.Ukunyibilikiswa kwe-aluminiyamu yi-fixed eziko eliqingqiweyo, umaleko ongasebenziyo kunye nefiber refractory eveziweyo kunye nodongwe lokugquma izitena zokumisa izitena, ichibi elityhidiweyo ngaphezu kwendawo yokusebenza eyenziwe ngezitena zodongwe, kodwa kukwafumaneka ii-alumina eziphezulu zokuchithwa kwe-refractory okanye iibhloko ezenziwe ngaphambili.Ukunyibilika pool umsebenzi umaleko ngokungqinelana nokusetyenziswa ubuchule ezahlukeneyo, impahla yayo ukwahluka, usebenzisa Al2O3 umxholo ngaphezu 75% of the high alumina refractory izitena wamatye okanye ngaphezulu, kodwa kufumaneka Al2O3 umxholo 80% ngaphandle castables alumina eliphezulu refractory. igalelwe kumaleko womsebenzi jikelele, xa kunyibilika i-aluminiyam yesinyithi esulungekileyo, umaleko womsebenzi wechibi lokunyibilika kufuneka ube sisitena esisulungekileyo se-mullite, isitena se-zircon okanye isitena se-corundum.Umlomo wokukhupha i-aluminium, itanki ye-aluminium ehambayo kunye ne-liner yayo, ukwenzela ukuxhathisa ukungena kunye nokukhukuliseka kolwelo lwe-aluminium, usebenzisa i-silicon carbide masonry yezitena ezinkulu.
Emva koko i-furnace induction enezixhobo eziphikisayo, ngokubanzi ngezitena zodongwe okanye amanqanaba amathathu e-alumina ephezulu ye-refractory.Ngaphantsi kweziko ngamanye amaxesha kugalelwa nge-alumina ephezulu ye-refractory castables kuqala, kwaye emva koko i-masonry ephezulu yezitena eziphikisayo ze-alumina.Xa umthamo we-furnace ye-induction ingaphantsi kwe-10t, umzimba wayo we-lining unokwenziwa nge-alumina ephezulu ye-refractory castable okanye i-refractory pounding material kunye nomxholo we-Al2O3 malunga ne-75%, kunye ne-corundum refractory castable or dry vibrating material iyafumaneka.I-liner ejikeleze ikhoyili ye-inductor yei-aluminiyam yokunyibilikisa izikoigalelwe nge-corundum refractory castables iyonke.
Iqokobhe le-slot induction liner ye-slot ye-10mm ye-asbestos sheet okanye i-refractory fiber ivalekile, kunye nodongwe lwama-masonry ukugquma izitena ezilahlayo okanye izitena zokujija iintsimbi ukwenzela umaleko wokugquma;umaleko womsebenzi kunye nekhoyili ejikeleze i-liner esetyenziswa ngokuxhaphakileyo ngodongwe olula ukungqubuzana kwezinto, kwakhona i-refractory ekhoyo yodongwe yokugalela imathiriyeli kwi-site yokugalela, i-slot enkulu yokufakwa kweziko lomsebenzi we-furnace, nayo iyafumaneka umxholo we-Al2O3 omkhulu kune-55% yokwakhiwa kwezitena eziphezulu ze-alumina refractory.
Izitena ezikwazi ukumelana nokufudumeza iziko elingasebenziyo elinezitena zodongwe zokugquma izitena, izitena ezikhukulisekayo okanye ipleyiti yokugquma.Ikwafumaneka kuxinaniso ngobuninzi be-0.8g/cm3 ukukhanya kwerefractory okugalelwa ukugalelwa;umaleko otyhidiweyo wokusebenza kwechibi usebenzisa i-Al2O3 emalunga ne-80% ye-alumina ephezulu ye-refractory yokwakhiwa kwezitena, kodwa iyafumaneka kwi-bulk density ye-2.4g/cm3 ephezulu ye-alumina erefractory yokugalela umlilo.Umaleko osebenzayo ongentla kwedama lokunyibilika ubotshwa ngokubanzi ngezitena zodongwe okanye iibhloko ezirhangqwayo ezilahlwayo, kwaye zinokugutyulwa ngeplastiki ephezulu ye-alumina erefractory.
Ngaphantsi, udonga kunye nophahla lwesithando somlilo segesi senziwa.Inokusetyenziswa ngokudibeneyo kunye ne-alumina reflection furnace.Isixhobo sayo se-furnace sitena sodongwe kunye nezitena eziphezulu ze-alumina refractory.
I-Aluminiyam yokusulungekisa izitena zodonga lwezitena ze-magnesium, ezinye iindawo ngezitena zodongwe kunye nezitena eziphakamileyo ze-alumina, i-electrolysis, iqondo lokushisa lomkhumbi ngokubanzi li-720-800 ℃, ubushushu bokusebenza buphantsi, ngoko ubomi benkonzo bude.
