I-Tabular Alumina Ye-Refractory Dry Ramming Mass I-Sintered Tabular Alumina Yezinto Zokusetshenziswa Ezingavuthi ...
Incazelo ye-Alumina yeThebula Ehlanganisiwe
I-corundum yethebula, obeye aziwe njengoi-alumina yetafula ehlanganisiwe, uhlobo oluhlanzekile kakhulu lwe-alumina (Al2O3) olucutshungulwa ngokukhethekile ukuze lube ne-ukuma kwethebula eliyingqayizivele, noma okuyisicabaIkhiqizwa ngokushisisa (ukushisa ngaphandle kokuncibilika) i-alumina powder yezinga eliphezulu emazingeni okushisa angaphezu kuka-1900°C, okubangela ukuthi izinhlayiya ze-alumina zikhule futhi zakhe amakristalu amakhulu, ayisicaba, afana nepuleti.
Imininingwane ye-Tabular Corundum
| Ukucaciswa kwe-corundum yethebula | ||
| Into | Okujwayelekile | Ukuhlolwa |
| Amandla adonsela phansi abonakalayo | 3.5g/cm3 iminithi | 3.56g/cm3 |
| Ukuvuleka Okubonakalayo | Ubuningi obungu-5.0% | 3.5% |
| Ukumuncwa Kwamanzi | Ubuningi obungu-1.5% | 1.1% |
| Ukwakheka Kwamakhemikhali | ||
| Into | I-% ejwayelekile | Isivivinyo % |
| I-Al2O3 | 99.2 min | 99.4% |
| I-Na2O | Ubuningi obungu-0.40 | 0.29% |
| I-Fe2O3 | Ubuningi obungu-0.10 | 0.02% |
| I-CaO | Ubuningi obungu-0.10 | 0.02% |

| Ukusetshenziswa: I-Tabular corundum isetshenziswa kabanzi ezintweni ezisebenza kahle kakhulu eziphikisayo emikhakheni yeinsimbi, ukubumba, amakhemikhali kaphethroli, izitini eziphefumulayo, ama-linings e-ladle, izinto eziphoswayo, izingxenye ezilungisiwe, izinto zobumba kanye neminye imikhakha. Kuyizinto zokwenziwa ezinhle kakhulu ezingamelani nokwakheka. I-tabular corundum isetshenziswa njengeIqoqo eliphikisayoingasetshenziswa ngokuhlanganiswa ne-spinel, i-alumina esebenzayo ene-calcined kanye nama-binding agents afana nesamente, ubumba noma i-resin. Izitini ze-corundum ezilungisiwe ezihlanzekile kakhulu zinokuqukethwe okuphansi kokungcola (njenge-SiO2), ubuningi obukhulu kanye nezakhiwo ezinhle ze-thermodynamic, okwenza izitini ze-corundum Izitini ziyamelana nomonakalo wokushisa, wamakhemikhali kanye nowesakhiwo obangelwa ukusebenza kwama-gasifier kanye nezinye izitofu zezimboni. | ||
| Izinzuzo:ukumelana okuphezulu kokugqwala; ukumelana okuphezulu kokugqwala; ukumelana okuphezulu kokuguguleka; ukumelana okuphezulu kokushaqeka kokushisa; amandla aphezulu, ukuqina okuhle; izakhiwo zamakhemikhali ezizinzile; ukumelana nokuguguleka kwe-alkaline slag, ukumelana okuhle nokuguguleka kwe-slag, kanye nokumelana okuhle nokuguguleka kwensimbi encibilikisiwe; ukumelana nokuguguleka kwensimbi encibilikisiwe kanye nokungena komoya okuhle. | ||
