IIMVELISO

Izitena eziKhala ngeMullite 1.0

Izitena ze-mullite ezikhaphukhaphu zenziwe ngezinto ezinqabileyo eziphakamileyo ezicocekileyo, ngokobunzima obufunekayo bemveliso, iifayili ze-organic composite zongezwa, i-vacuum extruded kunye ne-sintered kwiqondo lokushisa eliphezulu ukwenza iimveliso ze-mullite ezilula. Ngobunzima bayo obulula kunye nokusebenza okugqwesileyo kokufakelwa kwe-thermal, izitena ze-mullite ezikhaphukhaphu zisetyenziswa ngokubanzi kwi-linings eshushu ye-refractory okanye i-insulation layers yezixhobo ezahlukeneyo ze-thermal, ukudala iimeko zokuphucula izinga lokusetyenziswa kwamandla kwezixhobo.

Inkcazo ye-Lightweight Mullite Brick

Izinto eziphezulu ze-alumina eziphikisayo kunye ne-mullite njengesigaba esiphambili sekristale ngokubanzi sinomxholo we-alumina we-50% -75%. Ubushushu berefractory bezitena ezikhaphukhaphu mullite zinokufikelela ngaphezulu kwe-1790 ℃. Umthwalo wokuthambisa ubushushu bokuqala yi-1600-1700℃. Ukumelana noxinzelelo lobushushu begumbi kukukhanya kwe-70-260MPa. Ukumelana kakuhle nokothuka kwe-thermal. Kukho iindidi ezimbini: izitena ze-mullite ezidityanisiweyo kunye nezitena ezixutyiweyo ze-mullite.

Izitena ze-mullite ze-Sintered zenziwe nge-high-alumina bauxite clinker njengeyona nto iphambili eluhlaza, kunye nexabiso elincinci lodongwe okanye i-bauxite eluhlaza njenge-binder, kwaye yenziwe kwaye i-sintered. Izitena ze-mullite ezixutywe zenziwe nge-alumina ephezulu, i-alumina ye-industrial kunye nodongwe lwe-refractory, kunye ne-charcoal okanye i-coke particles emihle eyongeziweyo njenge-arhente yokunciphisa. Emva kokuqulunqa, zenziwe ngendlela yokunciphisa i-fusion. Iikristale ze-mullite edibeneyo zinkulu kunezo ze-sintered mullite, kwaye ukuxhathisa ukothuka kwe-thermal kungcono kuneemveliso ze-sintered. Ukusebenza kwabo okuphezulu kobushushu kuxhomekeke kumxholo we-alumina kunye nokufana kokusabalalisa kwesigaba se-mullite kunye neglasi.

I-alumina ephezulu ye-refractory material kunye ne-mullite (3Al2O3 · 2SiO2) njengesigaba esikhulu se-crystal. Umxholo we-alumina jikelele uphakathi kwe-65% kunye ne-75%. Ukongeza kwi-mullite, ukubunjwa kwamaminerali kuqulethe ixabiso elincinci leglasi kunye ne-quartz enomxholo ophantsi we-alumina; kunye nenani elincinci le-corundum enomxholo ophezulu we-alumina. Izitena ze-mullite ezilula zinokusetyenziswa ngokuthe ngqo kwi-kiln linings ephezulu, kwaye ngoku zisetyenziswa ngokubanzi kwii-shuttle kilns, i-roller kilns, iglasi kunye ne-petrochemical kiln linings.

Iiparamitha ezibonakalayo kunye neekhemikhali zezitena ze-mullite ezikhaphukhaphu zezi zilandelayo:

Iimpawu zesitena se-mullite esilula:

Isithando somlilo seFerrosilicon sisithando sombane sombane esidla amandla amaninzi kwaye luhlobo lwesithando somlilo se-arc. Isithando somlilo seFerrosilicon sibandakanya iqokobhe lesithando somlilo, isigqubuthelo sesithando somlilo, umnatha omfutshane, inkqubo yokupholisa amanzi, inkqubo yokukhupha umsi, inkqubo yokususa uthuli, iqokobhe le-electrode, ukukhutshwa koxinzelelo lwe-electrode kunye nenkqubo yokuphakamisa, inkqubo yokulayisha kunye nokukhulula, isilawuli, isixhobo sokutshisa, i-hydraulic. inkqubo, i-transformer kunye nezixhobo ezahlukeneyo zombane, njl. njl., ukusetyenziswa kwezinto eziphikisayo nazo zifuna kakhulu.

Ngo-2006, umzi-mveliso wethu wasekwa eYuzhou, isiseko se-bauxite ekrwada ekrwada ngumxube we-colloidal owahlulwe ngokucokisekileyo owenziwe nge-aluminiyam hydroxides kunye nemilinganiselo eyahlukeneyo. I-high-alumina bauxite kwi-industry refractory ngokuqhelekileyo ibhekisela kwi-bauxite ore kunye ne-calcined Al₂O₃ umxholo omkhulu kune-48% kunye nomxholo ophantsi we-Fe₂O₃.

Ifakwe kwi:

Glass ukunyibilika eziko upper isakhiwo eziphathekayo izitena channel, iipleyiti ukuguqulwa, processing isiko uphezulu isakhiwo, E-iglasi ukunyibilika izitena eziko. Iifiring kilns, izitofu zokunyibilikisa, izixhobo zokusulungekisa, izixhobo zokufudumeza, kunye nezinye izixhobo ezishushu. Imimandla yesicelo: ishishini le-ceramic, ishishini leglasi, ishishini lentsimbi, ishishini lepetrochemical, ishishini le-aluminiyam, kunye namanye amasimi oshishino.
