Izitena zeSilica Mullite: Isisombululo Esigqibeleleyo Sezicelo Zemizi-mveliso Ezinobushushu Obuphezulu

Kwihlabathi lemizi-mveliso eshushu kakhulu, ukukhethwa kwezinto ezinganyangekiyo kumisela ngokuthe ngqo ukusebenza kakuhle kwemveliso, ukhuseleko, kunye nolawulo lweendleko.Izitena zeSilica Mullite(ekwaziwa ngokuba ziiSilica-Mullite Refractory Bricks) ziye zatshintsha umdlalo, ngenxa yokuzinza kwazo okumangalisayo kobushushu, amandla aphezulu, kunye nokumelana nokugqwala okugqwesileyo. Nokuba usebenzisa i-oven yesamente, i-oven yeglasi, okanye i-boiler yemizi-mveliso, ezi zitena zibonelela ngokusebenza okungenakuthelekiswa nanto ukugcina imisebenzi yakho isebenza kakuhle.​

1. Kutheni izitena zeSilica Mullite zibonakala zibalasele: Iingenelo eziphambili​

Ngaphambi kokuba singene kwizicelo zabo, makhe sigxininise iimpawu eziphambili ezenza izitena zeSilica Mullite zibe yimfuneko kwiindawo ezishushu kakhulu:
Ukumelana noxinzelelo oluphezulu lobushushu:Xa zinomlinganiselo wokwanda kobushushu obuphantsi, zinokumelana notshintsho olukhawulezileyo lobushushu (ukusuka kubushushu obugqithisileyo ukuya ekupholeni) ngaphandle kokuqhekeka—okubalulekileyo kwiinkqubo ezinemijikelo yobushushu rhoqo.

Ukurhawuzelelwa okuphezulu:Zigcina ulwakhiwo lwazo lusemgangathweni kumaqondo obushushu afikelela kwi-1750°C (3182°F), nto leyo ezenza zibe zilungele amashishini apho ubushushu obugqithisileyo buhlala bungaguquki.

Amandla Abalaseleyo Oomatshini:Nokuba ziphantsi kwemithwalo ephezulu kunye noxinzelelo lobushushu, ziyamelana nokuguquguquka, nto leyo enciphisa isidingo sokutshintshwa rhoqo kunye nexesha lokungasebenzi.

Ukumelana nokugqwala kunye nokuKhukuliseka:Zimelana neendaba ezirhabaxa ezifana ne-slag enyibilikisiweyo, i-alkalis, kunye neegesi ze-acidic—ezixhaphakileyo kwisamente, isinyithi, kunye neglasi.

Ukuqhuba okuphantsi kobushushu:Inceda ukugcina ubushushu ngaphakathi kwee-oven okanye kwii-oven, iphucula ukusebenza kakuhle kwamandla kwaye inciphise iindleko zepetroli.

2. Izicelo eziphambili: Apho iSilica Mullite Bricks Excel​

Izitena zeSilica Mullite zinokusetyenziswa ngeendlela ezahlukeneyo kwaye zenzelwe ukuhlangabezana neemfuno ezikhethekileyo zemizi-mveliso eyahlukeneyo eshushu kakhulu. Nazi iindlela ezisetyenziswa ngazo kakhulu:

2.1 Ushishino lweSamente: IiKilns zoMbane kunye neendawo zokuKhala

Inkqubo yokwenziwa kwesamente ixhomekeke kubushushu obuphezulu obuqhubekayo—ingakumbi kwii-oven ezijikelezayo nakwiindawo ze-calcination. Izitena zeSilica Mullite zezona zikhethwayo apha kuba:

Zimelana nobushushu obugqithisileyo (1400–1600°C) kunye noxinzelelo loomatshini lwee-oven ezijikelezayo, apho ezinye izitena zihlala ziqhekeka okanye ziguge ngokukhawuleza.

Ukuxhathisa kwazo ukuhlaselwa yi-alkali (okuvela kwi-clinker yesamente) kuthintela ukuwohloka kwezitena, kwandisa ubomi benkonzo ye-oven kwaye kunciphisa iindleko zokulungisa.

Ityala Lokusetyenziswa:Izityalo ezinkulu zesamente kwihlabathi liphela zisebenzisa izitena zeSilica Mullite kwindawo etshayo kunye nendawo yokutshintsha yee-oven ezijikelezayo, zinciphisa ixesha lokungasebenzi nge-30% ngokomyinge.

2.2 Ushishino lweGlasi: Ukuqinisekisa Imveliso Ecacileyo neQondayo​

Izitofu zeglasi zisebenza kumaqondo obushushu angaphezulu kwe-1600°C, apho iglasi enyibilikisiweyo kunye neegesi eziguquguqukayo zibeka umngcipheko oqhubekayo kwizinto ezichasayo. Izitena zeSilica Mullite zisombulula le mingeni:

Ziyamelana nokugqwala okuvela kwiglasi enyibilikisiweyo kunye ne-boron oxides (exhaphakileyo kwimveliso yeglasi), ziphepha ungcoliseko oluchaphazela umgangatho weglasi.

Ukuzinza kwazo kubushushu kuqinisekisa ukusasazwa kobushushu okufanayo, kuthintela iindawo ezishushu ezibangela iziphene zeglasi (umz., amaqamza, ubukhulu obungalinganiyo).

Ilungele: Izinto zokuhlaziya, amagumbi okujonga, kunye neendawo zokunyibilikisa iglasi edadayo, iglasi yesikhongozeli, kunye neefeni zeglasi ezikhethekileyo.

2.3 Intsimbi kunye neMetallurgy: Ukumelana neMetal enyibilikisiweyo kunye neSlag​

Kwindlela yokwenza intsimbi, ingakumbi kwii-electric arc furnaces (EAFs) kunye nee-ladle furnaces, iiSilica Mullite Bricks zikhusela izixhobo kwintsimbi enyibilikisiweyo, i-slag, kunye neegesi ezishushu kakhulu:

Ziyanyamezela ukuguguleka kunye nefuthe lokuhamba kwesinyithi esinyibilikisiweyo, zinciphisa ukukhukuliseka kwezitena kwaye zandise ubomi be-lining yesithando somlilo.

Ukuchasana kwazo ne-iron oxide kunye nokugqwala kwe-slag kuthintela ukungaphumeleli kwe-lining okukhokelela ekumisweni kwemveliso okubiza kakhulu.

Indawo Yokusetyenziswa: Uphahla lweendonga ze-EAF, ii-ladle bottoms, kunye neenqanawa zokucoca zesibini.

2.4 Iibhoyila zemizi-mveliso kunye nee-Incinerators: Ukugcinwa kobushushu okuthembekileyo​

Ii-incinerators zenkunkuma kunye neebhoyila zemizi-mveliso (umz., zokuvelisa umbane) zijongene nobushushu obuphezulu kunye neegesi zokukhupha umbane ezirhabaxa. IiSilica Mullite Bricks zibonelela:

Ukugcinwa kobushushu ukuze kuphuculwe ukusebenza kakuhle kwebhoyila, kuncitshiswe ukusetyenziswa kwepetroli kunye nokukhutshwa kwekhabhoni.

Ukuxhathisa iigesi ezine-asidi (umz., i-SO₂, i-HCl) ekutshisweni kwenkunkuma, ukuthintela ukonakala kwezitena nokuqinisekisa ukusebenza ixesha elide.

Imeko yokusetyenziswa: Ukufakwa kweefeni zebhoyila, amagumbi okutshisa inkunkuma abe ngamandla, kunye nezixoxisi zobushushu.

2.5 Amanye Amacandelo Aphezulu Obushushu​

Izitena zeSilica Mullite nazo ziyasetyenziswa:

Ii-oven ze-ceramic:Ukutshisa iithayile zeseramikhi, izinto zokucoca, kunye neeseramikhi eziphambili, apho ulawulo lobushushu oluchanekileyo lubalulekile.

Iindawo zokuCoca iikhemikhali:Kwi-catalytic crackers kunye nabaguquli, abachasayo ubushushu obuphezulu kunye nokubola kwe-hydrocarbon.

Iifenitshala zeLebhu kunye noPhando:Kwi-R&D yezemfundo neyemizi-mveliso, apho uzinzo kumaqondo obushushu aphezulu lungenakuxoxiswana.​
