Intshayelelo kwisakhiwo sokuqala sokugquma somlilo kunye nomlilo oshushu:

Isithando somlilo luhlobo lwezixhobo ezishushu ezinesakhiwo esintsonkothileyo. Sesona sixhobo siphambili sokwenza i-ironmaking kwaye inezibonelelo zemveliso enkulu, imveliso ephezulu kunye neendleko eziphantsi.
Kuba ubushushu obusebenzayo becandelo ngalinye lesithando somlilo siphezulu kakhulu, kwaye icandelo ngalinye linemiphumela yoomatshini, njengokukhuhlana kunye nefuthe lentlawulo ewayo, uninzi lwezinto ezishushu ezishushu zisebenzisa i-CCEFIRE iqondo lobushushu eliphezulu lezitena ezizayo ngamaqondo obushushu athambileyo aphezulu phantsi komthwalo kunye namandla aphezulu oomatshini aphezulu.
Njengenye yezixhobo eziphambili ezincedisayo kwisithando somlilo, isithando somlilo esishushu sibonelela ngomsindo oshushu oshushu kwisithando somlilo ngokusebenzisa ubushushu obusuka ekuvutheni komlilo wegesi kunye nefuthe lokutshintshiselana ngobushushu kwileta yezitena. Ukusukela ukuba icandelo ngalinye lithwala ukushukuma okuphezulu kwe-temp yokutsha kwegesi, ukhukuliseko lothuli oluziswe yigesi, kunye nokutyakatywa kwerhasi yokutsha, indawo eshushu yomhlaba ihlala ikhetha i-CCEFIRE izitena zokugquma ukukhanya, ikhonkrithi enganyangekiyo ngobushushu, izitena zodongwe, kunye nezinye izixhobo ezinamandla oomatshini elungileyo.
Ukuze kuqinisekiswe ngokupheleleyo ukufakwa kwe-thermal kwisithando somlilo, ngokuthobela imigaqo-nkqubo yokukhetha izinto ezinokuthenjwa, ezinoqoqosho kunye nezifanelekileyo, umgca wendawo yokusebenza eshushu yesithando somlilo kunye nesithando sayo esitshisayo sisoloko sikhetha izinto zokufakelwa ukuqhuba kwe-thermal esezantsi kunye nokusebenza kakuhle kokugquma.
Eyona ndlela yesiqhelo kukukhetha iimveliso zebhodi ye-calcium, enolu lwakhiwo oluthile lokugquma ubushushu: izitena ezikhanyayo eziphezulu zealuminium + iibhodi zesilica-calcium isakhiwo esine-thermal insulation thickness about 1000mm.

Olu lwakhiwo lwe-thermal insulation luneziphene zilandelayo kwisicelo:

A. Izinto zokwambathisa ubushushu zinokuqhutywa kwe-thermal enkulu kunye nefuthe elibi lokugquma ubushushu.
B. Iibhodi ze-silicon-calcium ezisetyenziswe kumaleko angasemva angangena ngokulula, enze imingxunya emva kokuba yaphulwe, kwaye ibangele ukulahleka kobushushu.
C. Ukulahleka kobushushu obukhulu, okukhokelela kwinkunkuma yamandla.
D. Iibhodi ze-calcium silicate zinokufakwa ngamandla kwamanzi, kulula ukuzaphula, kwaye zisebenza gwenxa kulwakhiwo.
E. Ubushushu bokusetyenziswa kweebhodi ze-calcium silicate buphantsi kuma-600 ℃
Izinto zokwambathisa ezishushu ezisetyenziswa kwiziko lokuqhushumba kunye neziko lalo elitshisayo kufuneka libe nokusebenza kakuhle kwe-thermal insulation. Nangona ukuhanjiswa kwe-thermal yeebhodi ze-calcium silicate kungaphantsi kunezo zezitena ezichasayo kwaye ukusebenza kwe-thermal kuphuculwe, ngenxa yokuphakama komzimba omkhulu weziko kunye neeramitha ezinkulu zomlilo, iibhodi ze-calcium silicate ziqhekeka ngokulula ngexesha lenkqubo yokwakha ngenxa yabo ubungqindilili, okukhokelela kukungqinwa okungaphakathi okungagqibelelanga kokufakwa ngaphakathi kunye neziphumo zokugquma ezingonelisiyo. Ke ngoko, ukuze kuphuculwe ngakumbi ukufakwa kwe-thermal ye-metallurgical blast oven kunye ne-hot blast, i-CCEWOOL iimveliso ze-ceramic fiber (izitena / iibhodi) ziye zaba yinto efanelekileyo yokubambisa.

Uhlalutyo lwee-ceramic fiberboards 'zomsebenzi wobugcisa:

I-CCEWOOL fiberboard yodongwe yamkela i-AL2O3 esemgangathweni + SiO2 = i-97-99% yemicu njengezinto ezingavunyelwanga, zidityaniswe nezihlanganisi ezingaphiliyo njengezona zinto ziphambili zomzimba kunye nokuzaliswa kwetempile ephezulu kunye nezongezo. Zenziwe ngokuxhokonxa kunye nokuhluza kunye nokucoca. Emva kokuba iimveliso zomile, ziqhubekiswa ngothotho lwezixhobo zobuchwephesha ukugqibezela iinkqubo zokulungisa, ezinje ngokusika, ukusila, kunye nokomba ukuqinisekisa ukuba ukusebenza kwemveliso kunye nokuchaneka komlinganiso kukwinqanaba eliphambili lamazwe. Ezona zinto ziphambili kubuchwephesha zibandakanya:
a. Ukucoceka okuphezulu kwemichiza: iqulethe i-97-99% yeqondo lobushushu obuphezulu njenge-Al2O3 kunye ne-SiO2, eqinisekisa ukumelana nobushushu kweemveliso. I-fiberboard ye-CCEWOOL yeceramic ayikwazi ukubuyisela kuphela iibhodi ze-calcium silicate njengodonga lwesithando somlilo, kodwa isetyenziswe ngokuthe ngqo kwindawo eshushu yeendonga zesithando ukuze ibaxhobise ngokhukuliseko lomoya.
b. Ukuqhutywa kwe-thermal ephantsi kunye nefuthe elifanelekileyo lokugquma ubushushu: Ngenxa yokuba le mveliso iyimveliso yefayibha yeCCEWOOL eveliswe yinkqubo ekhethekileyo yemveliso eqhubekayo, inentsebenzo engcono kunesitena somhlaba esiqhelekileyo sezitena, iibhodi ze-calcium silicate kunye nezinye izinto ezixhasayo ezixhasayo kwi-thermal ephantsi ukuqhuba, iziphumo ezingcono zokulondolozwa kobushushu, kunye neempembelelo ezibonakalayo zokonga amandla.
c. Amandla aphakamileyo kunye nokusebenziseka lula: Iimveliso zinamandla aphezulu okucinezela kunye nokuguquguquka kwaye azizinto ezomeleleyo, ngenxa yoko ziyahlangabezana ngokupheleleyo neemfuno zezinto ezilukhuni zokubopha umva. Zingasetyenziselwa naziphi na iiprojekthi zokugquma ezineemfuno zamandla aphezulu, endaweni yezinto zangasemva zokufaka iingubo okanye iifelts. Ngeli xesha, ii-fiberboard zeceramic zeCCEWOOL ezicwangcisiweyo zinobungakanani obuchanekileyo bejiyometri kwaye zinokunqunyulwa kwaye zilungiswe ngokuthanda. Ulwakhiwo lulunge kakhulu, olusombulula iingxaki zobukrakra, ubu-ethe-ethe kunye nenqanaba lomonakalo omkhulu wokwakha iibhodi ze-calcium silicate. Balinciphisa kakhulu ixesha lokwakha kunye nokunciphisa iindleko zokwakha.
Isishwankathelo, i-CCEWOOL ifreyibhodi yodongwe eveliswe ngocoselelo olungagcini nje ngokuba neepropathi zoomatshini ezibalaseleyo kunye nemilinganiselo yejiyometri, kodwa ikwagcina ezona mpawu zibalaseleyo zezixhobo zokugquma ubushushu. Banokutshintsha iibhodi ze-calcium silicate kwaye basetyenziswe kwiindawo zokugquma ezifuna ukuqina kunye nokuzixhasa kunye nokumelana nomlilo.

Ukusetyenziswa kwesixhobo sokubetha kwesinyithi kunye nomlilo oshushu

I-fiberboard ye-CCEWOOL yodongwe inokuthi ithathe indawo yesakhiwo sebhodi ye-calcium (okanye i-diatomaceous earth brick), kwaye ngenxa yeenzuzo zabo, ezifana nokuqhuba kwe-thermal ephantsi, ukushisa okuphezulu ekusebenziseni, ukusebenza ngokugqwesileyo, kwaye akukho ukuxutywa kwamanzi, bazisombulula ngokufanelekileyo iingxaki ulwakhiwo lwantlandlolo, umzekelo, ifuthe elibi lokugquma ubushushu, ukulahleka kobushushu okukhulu, izinga eliphezulu lomonakalo weebhodi zekhalsiyam, ukusebenza kakubi kolwakhiwo, kunye nobomi obufutshane benkonzo yokugquma. Bafezekisile iziphumo ezilungileyo kakhulu zesicelo.
