Izitini Eziphakeme Ze-Alumina Zemboni Yensimbi
IMIKHIQIZO
Isitini Sokuhlola I-Alumina Ephakeme (Izimbobo Ze-Checker Brick-19)
Incazelo High Alumina Checker Brick
Uma okuqukethwe kwe-Al2O3 kungaphezulu kuka-90%, kubizwa nge-corundum brick. Ngenxa yezinsiza ezahlukene, izindinganiso zamazwe ahlukahlukene azihambisani ngokuphelele. Isibonelo, amazwe aseYurophu abeka ukuthi umkhawulo ophansi we-Al2O3 okuqukethwe kwe-high-alumina refractories ngu-42%. E-China, izitini eziphakeme ze-alumina ngokuvamile zibhekisela ezitini eziphikisayo ezinokuqukethwe kwe-Al2O3 okungaphezu kuka-48%. Ikakhulukazi zenziwe nge-bauxite yemvelo yezinga eliphezulu, equkethe amaminerali afana ne-diaspore, i-bomerite, i-kaolinite, njll. Ubumba oluthambile noma oluncane oluthambile lwengezwa ku-clinker ye-alumina ephezulu njenge-binder ukuze kuqale ukuxutshwa nokuxutshwa, bese iyakhiwa, yomiswe, futhi ekugcineni ixoshwe. I-refractoriness yezitini eziphakeme ze-alumina cishe i-1770 ℃, futhi izinga lokushisa lokuthambisa umthwalo liyi-1420 ℃-1550 ℃. Izitini ezivamile ze-alumina ezivamile ziyi-LZ-80, LZ-75, LZ-65, LZ-55, LZ-48, njll. Isetshenziselwa ikakhulukazi ulwelwesi lwesithando somlilo, isithando somlilo esishisayo, isithando somlilo se-ore-heat, uphahla lwesithando sikagesi, ukuqhuma. isithando somlilo, isithando somlilo esiphendulayo kanye nohhavini ojikelezayo. Ngaphezu kwalokho, izitini eziphakeme ze-alumina nazo zisetshenziswa kabanzi njengezitini zokuhlola isitoreji sokushisa esivulekile, amapulaki okuthela amasistimu, izitini ze-nozzle, njll.

Isicelo Of High Alumina Checker Brick
Izitini Zokuhlola I-Alumina Ephakeme zisetshenziswa kakhulu kwiziko lomlilo elishisa izikhotha namalangabi omlilo.
Izitini Zokuhlola I-Alumina Ephakeme zisetshenziswa kakhulu ekukhiqizeni kabusha izitofu ezishisayo. I-High Alumina Checker Brick enesakhiwo esithile kanye nezimbobo zegridi zihlelwa ngendlela ehlelekile. Ingaphezulu naphansi ngokusebenzisa izimbobo zezitini zokuhlola kungavumela igesi ukuba idlule. Ngokwezidingo zobuchwepheshe zezindawo zokushisa ezihlukene, izitini zesheke ze-siliceous, izitini zobumba, njll zivame ukusetshenziswa. Kwezinye izitofu ezishisayo, izitini eziphakeme ze-alumina, izitini ze-mullite, izitini ze-sillimanite, njll. nazo zikhethiwe.
Umsebenzi wesitofu se-hot blast stove ukushisa umoya obandayo othunyelwe i-blower esithandweni somlilo emoyeni oshisayo, bese uthumela umoya oshisayo esithandweni somlilo ngokusebenzisa i-hot blast duct ukuze kutholakale ukusabela komlilo. I-blast furnace hot blast stove inesikhathi sokushiswa kwesithando somlilo kanye nesikhathi sokunikezwa komoya, futhi izikhathi ezimbili zokusebenza zijikeleza ngezikhathi ezithile. Ngesikhathi sokushisa, i-flue gas eshisiwe yokushisa ephezulu idlula emigodini yezitini zokuhlola zesithando somlilo esishisayo futhi idlulisela ukushisa ezitini zokuhlola; phakathi nesikhathi sokuhlinzeka komoya, umoya obandayo ovela ku-blower ungena esithandweni somlilo oshisayo futhi ushiswa izitini zokuhlola emoyeni oshisayo. Kuthunyelwe esithandweni somlilo ngepayipi lomoya oshisayo.
