Ubunzima bokukhanya kweSitena seSilica 1.2

Izitena ze-silica ezilula zisebenzisa i-silica ecolekileyo njengento ekrwada, kwaye ubungakanani bamasuntswana abalulekileyo ngokuqhelekileyo abukho ngaphezu kwe-1mm, kwaye iinqununu ezingaphantsi kwe-0.5mm azikho ngaphantsi kwe-90%. Izinto ezivuthayo zongezwa kwizithako okanye indlela yokuvelisa igesi isetyenziselwa ukwenza isakhiwo se-porous, esiye sigxothwe. Isenokwenziwa kwakhona kwiimveliso ezingatshiswa. Isetyenziswa kakhulu kwiindawo ezahlukahlukeneyo ze-kilns ezifuna ukugquma okanye ukunciphisa umzimba ngaphandle kokudibanisa ngokuthe ngqo kunye ne-melted, ngaphandle kwempembelelo yeegesi ezinobungozi, kwaye ngaphandle kokutshintsha ngokukhawuleza kweqondo lokushisa. Isetyenziswe kumaqondo okushisa aphezulu kwaye ayikwazi ukudibana nezinto ezinqandayo ze-alkaline. Ngokuxhomekeke kwizinto eziphathekayo, ubushushu bokusetyenziswa kwayo buphakathi kwe-1200 kunye ne-1550 ℃.

Izitena ze-silica ezilula zizinto ezikhethekileyo kakhulu, ezisetyenziswa kakhulu kwishishini leglasi kunye neshishini lensimbi. Kwiimeko ezininzi, izitena ze-silica ezikhaphukhaphu kunye nezitena ezishinyeneyo ze-silica zisetyenziswa njengenxalenye yesakhiwo. Ngokuqhelekileyo isetyenziswa kushishino lweglasi ye-kiln, ngokukodwa ukufakwa kwe-vault ye-kiln, ngokunciphisa ilahleko yobushushu kunye nokwandisa ukusebenza kakuhle kwenkqubo yokunyibilika. Kwishishini lokwenza intsimbi, izitena ze-silica ezikhaphukhaphu zisetyenziselwa ukukhanya kweendonga zesithando somlilo kunye nezindlu.

1. Izitena ze-silica ezilula zisetyenziswa kwishishini leglasi - i-thermal insulation of vaults

Kwinkqubo yokunyibilika kweglasi, amaqondo obushushu aphezulu afikeleleka kwindawo esezantsi ephakanyisiweyo. Kuxhomekeke kuhlobo lweglasi, iqondo lobushushu limalunga ne-1600°C. Umaleko okhanyayo udla ngokuyilwa njengemigangatho emibini okanye ngaphezulu.

Izitena ze-silica ezilula kakhulu zibonakaliswe kule mithwalo yeqondo lokushisa. Kulindeleke ukuba umaleko omnye wevault (isakhiwo kunye ne-lightweight layer) ineempawu ezifanayo okanye ezifanayo zokwandisa. Izitena ze-silica ezinobuninzi obuninzi be-1250kg · m-3 okanye i-1000kg · m-3 inokuhlangabezana neemfuno zoluhlu oluxineneyo. Umaleko olandelayo usebenzisa izitena ze-silica ezinobuninzi be-800Kg · m-3 okanye 600kg · m-3.

Izitena ze-silica ezilula zinokuthi zifakwe ngokukhululekileyo kwi-vault yesithando somlilo okanye ziboshwe ngodongwe lomlilo we-silica. Akukho mthwalo weekhemikhali ngexesha lobomi benkonzo yesithando somlilo (iminyaka emininzi). Izitena ze-silica ezilula zisetyenziswa kakhulu ngenxa yokuba ukubunjwa kweekhemikhali kunye ne-mineral ye-lining yokusebenza kufana ne-dense ye-silica izitena ezisetyenzisiweyo.

2. Izitena ze-silica ezikhaphukhaphu zisetyenziswa kwishishini letsimbi - ii-furnaces ezitshisayo

Iziko lokutshisa okutshisayo lihlala lisetyenziselwa umoya oshushu (obizwa ngokuba yi-blast furnace blast), edityaniswe ne-fan exhaust ye-blast furnace. Ngokuxhomekeke kwimilo kunye nendawo yesithando somlilo esitshisayo, iqondo lokushisa liphakathi kwe-1000 kunye ne-1300 ° C, kwaye umoya oshushu uphakathi kwe-2300 ukuya kwi-6500 m3 · min-1.

Oku kufuna ukubala uthelekiso phakathi kwesithando somlilo esitshisayo (ubukhulu becandelo elahlukeneyo kunye neendawo zokusetyenziswa) kunye nedome yeglasi yeglasi kumanqanaba ahlukeneyo kunye nemithwalo eyahlukeneyo, igxile kwiipropati ze-thermomechanical. Kumaleko alula, ubuninzi bomthamo osetyenziswayo yi-1250kg·m-3 okanye 1050kg·m-3 (ikakhulu ngenxa yamandla abo aphezulu)
