Izitena eziphezulu ze-Alumina eziRefractory: AbaGcini abathembekileyo bamaShishini aPhakamileyo

Kwintsimi yamashishini aphezulu obushushu, ukusebenza kwezinto eziphathekayo kubeka ngokuthe ngqo ukuzinza kunye nokusebenza kakuhle kwemveliso.Izitena eziphezulu ze-alumina refractory, njengemathiriyeli ekumgangatho ophakamileyo we-refractory eyenziwe ikakhulu kwi-bauxite ye-alumina ephezulu, ibe lolona khetho lufanelekileyo kumashishini amaninzi anobushushu obuphezulu kunye nokusebenza kwawo okugqwesileyo, ukukhusela uphuhliso lwesinyithi sehlabathi, izixhobo zokwakha, iikhemikhali kunye namanye amashishini.

Iinzuzo eziphambili zezitena eziphezulu ze-alumina eziphikisayo zivela ekubunjweni kwazo ezizodwa kunye nenkqubo yokuvelisa. Ezi zitena zenziwe kwi-high-alumina bauxite clinker kunye nomxholo we-alumina ongekho ngaphantsi kwe-48% njenge-aggregate, idityaniswe nezibophelelo ngomlinganiselo ohlukeneyo, kwaye emva koko zenziwe, zomiswe, kwaye zitshiswe kumaqondo aphezulu. Izitena eziphezulu ze-alumina refractory zine-refractoriness egqwesileyo, ekwazi ukumelana nobushushu obuphezulu ukusuka kwi-1770 ° C ukuya kwi-1790 ° C. Nakwiindawo eziphakamileyo zobushushu obuphezulu, banokugcina ingqibelelo yesakhiwo, baxhathise ngokufanelekileyo ukukhukuliseka kwamaqondo obushushu aphezulu kwizixhobo. Umthwalo wabo omhle wokunciphisa izinga lokushisa liqinisekisa ukuba abanako ukuguqulwa kunye nokuwa phantsi koxinzelelo oluthile kunye nokushisa okuphezulu, ukubonelela ngeziqinisekiso ezithembekileyo zokusebenza okuzinzile kwezixhobo eziphezulu zokushisa. Ukongeza, izitena eziphezulu ze-alumina eziphikisayo zinokuxhathisa ukothuka kwe-thermal, ezivumela ukuba zigcine ukusebenza okuzinzile ngexesha lokutshintsha kwamaqondo obushushu rhoqo, ukunciphisa ukuqhekeka kunye nokusabalalisa okubangelwa kuxinzelelo lwe-thermal kunye nokwandisa ubomi babo benkonzo. Bakwanazo nokuxhathisa ngamandla kwizinto ezahlukeneyo zemichiza. Enoba yi-slag kwinkqubo ye-metallurgical okanye iigesi ezonakalisayo kwimveliso yemichiza, kunzima ukwenza umonakalo omkhulu kuzo.

Izitena eziphezulu ze-alumina refractory zineendlela ezininzi zokusetyenziswa. Kwimizi-mveliso yesinyithi, zizinto eziphambili zokwenziwa kweziko lokwenza intsimbi, iziko zokwenza intsimbi, kunye neziko lokufudumeza kwakhona. Bangakwazi ukuxhathisa ngokufanelekileyo ukukhukuliseka kwensimbi etyhidiweyo ephezulu yobushushu kunye ne-slag, ukuqinisekisa inkqubela phambili yenkqubo yokunyibilikisa kunye nokuphucula ubomi benkonzo yezixhobo kunye nokusebenza kakuhle kwemveliso. Kwishishini lezinto zokwakha, izitena eziphezulu ze-alumina refractory zisetyenziswa ngokuqhelekileyo kwizixhobo ezifana ne-sement rotary kilns kunye ne-glass melting furnaces. Kwiindawo ezinamaqondo okushisa aphezulu, ukutyhulwa kwe-air-speed-speed, kunye ne-abrasion yezinto eziphathekayo, basenokugcina ukusebenza kakuhle, ukuxhasa ukusebenza okuzinzile kokuveliswa kwezinto zokwakha. Kwishishini lemichiza, izitena eziphezulu ze-alumina refractory zidlala indima ebalulekileyo kwi-high-temperature reaction furnaces kunye ne-gasifiers. Ngokumelana kwabo okugqwesileyo kweekhemikhali, baqinisekisa ukhuseleko kunye nokusebenza kakuhle kwenkqubo yokuvelisa imichiza

Sixhotyiswe ngezixhobo zemveliso eziphambili kunye nenkqubo engqongqo yokulawula umgangatho. Yonke ikhonkco, ukusuka ekuthengeni izinto eziluhlaza ukuya ekunikezelweni kwemveliso egqityiweyo, ibekwe esweni ngononophelo. Ngokwamkela iinkqubo zemveliso ehamba phambili kumazwe ngamazwe, siqinisekisa ukuba umgangatho wezitena eziphezulu ze-alumina refractory uhlangabezana nemigangatho yamazwe ngamazwe. Kwangaxeshanye, sikwabonelela ngenkxaso yobuchwephesha yobuchwephesha kunye neenkonzo ezibanzi emva kokuthengisa. Ngokweemfuno ezahlukeneyo zabathengi, sinikezela ngezisombululo ezizezakho zokuqinisekisa ukuba izitena eziphezulu ze-alumina refractory zinokusebenza ngokugqibeleleyo kwizicelo ezisebenzayo.

Ukukhetha izitena zethu eziphezulu ze-alumina refractory kuthetha ukukhetha umgangatho kunye nokuthembeka. Nokuba ufuna ukuthengwa kwezinto ezinkulu okanye izisombululo zemathiriyeli yobuchwephesha, sinokuhlangabezana neemfuno zakho. Samkela ngokufudumeleyo abathengi abavela kwihlabathi liphela ukuba baqhagamshelane nathi kwaye basebenze kunye ukudala ikamva eliqaqambileyo kushishino lobushushu obuphezulu!
