Kwiinkqubo zoshishino ezishushu kakhulu ezifana nokuveliswa kwesamente, ukwenziwa kwentsimbi, kunye nokuveliswa kweglasi, izixhobo ezichasayo zibalulekile kuzinzo lokusebenza kunye nolawulo lweendleko.Izitena ze-spinel zeMagnesia alumina, ukhetho oluphezulu kubasebenzisi bemizi-mveliso kwihlabathi liphela, lubalasele ngokuqina okumangalisayo kobushushu, ukumelana nokugqwala, kunye nobuhlobo nokusingqongileyo.Esi sikhokelo sichaza izinto ezibalulekileyo ezisisiseko zezitena ze-magnesia alumina spinel ezilungele iimfuno zakho zoshishino.
1. Inkcazelo yeeMagnesia Alumina Spinel Bricks
Izitena ze-spinel zeMagnesia alumina zizinto ezivuselelayo ze-alkaline ezenziwe ngokuyintloko nge-magnesium oxide ecocekileyo kakhulu (i-MgO, 80%-92%) kunye ne-aluminium oxide (i-Al₂O₃, 3%-14%). Iinqanaba zazo eziphambili zekristale—i-periclase kunye ne-magnesia-alumina spinel (i-MgO·Al₂O₃)—zakha isakhiwo esizinzileyo ngokusila ngobushushu obuphezulu. Njengendlela engena-chromium-free refractories kune-refractories zemveli, izitena ze-spinel zeMagnesia alumina ziphepha ukukhutshwa kwe-chromium enetyhefu ene-hexavalent, zihambelana ngokupheleleyo nemigangatho yokusingqongileyo yehlabathi.
2. Iipropati eziphambili zeMagnesia Alumina Spinel Bricks
Iimpawu ezibalaseleyo zezitena ze-magnesia alumina spinel ziquka:
- ① Uzinzo oluhle kakhulu lobushushu, olumelana nemijikelo yokupholisa amanzi eyi-12-20 kwi-1100°C;
- ② Ukumelana okuphezulu nobushushu obuphezulu, okuneqondo lokunyibilika elingama-2135°C kunye nokungaguquguquki komthwalo >1700°C;
- ③ Ukumelana okunamandla kokugqwala kunye ne-slag ngokuchasene ne-alkaline slags, iigesi ze-asidi, kunye neentsimbi ze-alkali;
- ④ Amandla okwakha anokuthenjwa, anobunzima obuyi ≥2.90 g/cm³ kunye namandla okutyumza abandayo ayi ≥45 MPa.
3. Usetyenziso oluPhambili lweMagnesia Alumina Spinel Bricks
Izitena ze-Magnesia alumina spinel zilungele iimeko ezinzima zobushushu obuphezulu: iindawo zokutshintsha i-samente rotary kiln, ii-ladle linings zentsimbi, ii-regenerators ze-glass furnace, kunye nee-petrochemical furnace linings. Ukuguquguquka kwazo kwenza izitena ze-magnesia alumina spinel zilungele zombini imisebenzi ye-alkaline kunye ne-mixed atmosphere.
4. Iingcebiso zokukhetha izitena ze-Magnesia Alumina Spinel
Xa ukhetha izitena ze-magnesia alumina spinel, gxila kwiingongoma ezintathu ezibalulekileyo: fanisa umlinganiselo we-MgO/Al₂O₃ nomoya wenkqubo yakho, qinisekisa iiparameter zobugcisa eziphambili (ubuninzi bobuninzi, ukumelana noxinzelelo lobushushu), kwaye ujonge iziqinisekiso zomgangatho womthengisi.Beka phambili izitena ze-magnesia alumina spinel ezivavanyiweyo kwimeko yakho yemizi-mveliso ukuqinisekisa ukusebenza kakuhle kunye nobomi benkonzo ende.
Izitena ze-Magnesia alumina spinel zidibanisa ukusebenza kunye nokuzinza, nto leyo ezenza zibe lutyalo-mali olukrelekrele kumashishini anamhlanje ashushu kakhulu. Khetha izitena ze-magnesia alumina spinel ezifanelekileyo ukuphucula ukuthembeka kwezixhobo kunye nokunciphisa iindleko zokulungisa.
