I-Tabular Alumina ye-Refractory Dry Ramming Mass Sintered Tabular Alumina ye-Refractory Raw Materials
Incazelo ye-Sintered Tabular Alumina
I-tabular corundum, obeye aziwe njengoi-alumina ye-tabular ehlanganisiwe, iwuhlobo lokuhlanzeka okuphezulu kwe-alumina (Al2O3) ecutshungulwa ngokuqondile ukuze ibe nei-tabular ehlukile, noma umumo oyisicaba.Ikhiqizwa nge-sintering (ukushisa ngaphandle kokuncibilika) i-alumina powder yezinga eliphezulu emazingeni okushisa angaphezu kuka-1900 ° C, okwenza izinhlayiya ze-alumina zikhule futhi zenze amakristalu amakhulu, ayisicaba, afana nepuleti.
Ukucaciswa kweTabular Corundum

| Ukusetshenziswa: I-tabular corundum isetshenziswa kabanzi ezintweni eziphikisayo ezisebenza kakhulu emikhakheni yeinsimbi, ukubunjwa, amakhemikhali ephethiloli, izitini eziphefumulayo, amalayili e-ladle, izinto ezisansimbi, izingxenye ezakhiwe ngaphambili, izitsha zobumba nezinye izinkambu.Kuyinto enhle kakhulu yokwenziwa refractory impahla eluhlaza.I-tabular corundum isetshenziswa njengeI-refractory aggregateingasetshenziswa ngokuhambisana ne-spinel, i-alumina evuliwe e-calcined kanye nama-agent abophayo afana nosimende, ubumba noma i-resin.Izitini ze-corundum ezilungisiwe ezihlanzekile zinokuqukethwe kokungcola okuphansi (okufana ne-SiO2), ukuminyana okuphezulu kwenqwaba kanye nezakhiwo ezinhle ze-thermodynamic, okwenza izitini ze-corundum Izitini zimelana nomonakalo oshisayo, wamakhemikhali kanye nesakhiwo obangelwa ukusebenza kwamagesi nezinye iziko lezimboni. | ||
| Izinzuzo:high refractoriness;ukumelana nokugqwala okuphezulu;ukumelana nokuguguleka okuphezulu;ukumelana nokushaqeka okuphezulu kokushisa;amandla aphezulu, ukuqina okuhle;ezinzile izakhiwo zamakhemikhali;ukumelana nokuguguleka kwe-alkaline slag, ukumelana kahle nokuguguleka kwe-slag, nokumelana kahle nokuguguleka kwensimbi encibilikisiwe;Imelana nokuguguleka kwensimbi encibilikisiwe kanye nokungena komoya okuhle. | ||
