Ironmaking Blast Furnaces kunye neHot-blast Furnaces

Intshayelelo yesakhiwo sokuqala sokufakelwa kwezitofu eziqhumayo kunye neziqhumiso ezishushu:

Isithando somlilo luhlobo lwezixhobo ezishushu kunye nesakhiwo esinzima. Sesona sixhobo siphambili sokwenza intsimbi kwaye ineenzuzo zemveliso enkulu, imveliso ephezulu, kunye neendleko eziphantsi.
Ekubeni ubushushu obusebenzayo benxalenye nganye yesithando somlilo siphezulu kakhulu, kwaye inxalenye nganye ixhomekeke kwimiphumo yomatshini, njengokungqubuzana kunye neempembelelo zentlawulo ehlayo, ininzi ye-refractories eshushu eshushu zisebenzisa i-CCEFIRE izitena zokukhanya eziphezulu zokushisa eziza kunye nokushisa okuphezulu okuthambisa phantsi komthwalo kunye namandla alungileyo omatshini wokushisa.
Njengenye yezixhobo eziphambili ezincedisayo zesithando somlilo, i-hot blast furnace inika i-high-temp hot blast kwi-flash furnace ngokusebenzisa ubushushu obuvela kwi-blast furnace gas combustion kunye nefuthe lokutshintshana kobushushu kwi-lattice yezitena. Kuba indawo nganye inobushushu obuphezulu bokutsha kwerhasi, ukukhukuliseka kothuli oluziswa yirhasi, kunye nokuhlanjwa kwerhasi yokutsha, iirefractories ezishushu zidla ngokukhetha izitena zokwaleka ukukhanya kweCCEFIRE, ikhonkrithi ekwaziyo ukumelana nobushushu, izitena zodongwe, kunye nezinye izinto ezinamandla omatshini.
Ukuze kuqinisekiswe ngokupheleleyo iimpembelelo ze-thermal insulation of the furnace lining, ukuthobela imigaqo yokukhetha izinto ezinokwethenjelwa, ezinoqoqosho kunye nezinengqiqo, i-lining of the working surface eshushu yesithando somlilo kunye nesithando somlilo esitshisayo ngokuqhelekileyo sikhetha izinto zokugquma ezine-conductivity ephantsi ye-thermal kunye nokusebenza kakuhle kwe-insulation.
Indlela yendabuko ngakumbi kukukhetha iimveliso zebhodi ze-calcium silicate, ezinale sakhiwo sikhethekileyo sokufakelwa kwe-thermal: izitena ezikhanyayo eziphezulu ze-aluminium + i-silica-calcium iibhodi zesakhiwo kunye nobukhulu be-thermal insulation malunga ne-1000mm.

Esi sakhiwo sokufakelwa kwe-thermal sineziphene ezilandelayo kwisicelo:

A. Izinto zokufakelwa kwe-thermal zine-conductivity enkulu ye-thermal kunye nemiphumo emibi ye-thermal insulation.
B. Iibhodi ze-silicon-calcium ezisetyenziswe kwi-back lining layer zinokuphuka lula, zenze imingxunya emva kokuphulwa, kwaye zibangele ukulahleka kobushushu.
C. Ilahleko enkulu yokugcina ubushushu, ekhokelela kwinkcitho yamandla.
D. Iibhodi ze-calcium silicate zinamanzi anamandla, zilula ukuphuka, kwaye ziqhuba kakubi ekwakheni.
E. Ubushushu besicelo seebhodi ze-calcium silicate ziphantsi kwi-600℃
Izinto zokufakelwa kwe-thermal ezisetyenziselwa kwisithando somlilo kunye nesithando somlilo esivuthayo kufuneka sibe nokusebenza kakuhle kwe-thermal insulation. Nangona i-thermal conductivity yeebhodi ze-calcium silicate iphantsi kunezitena eziphikisayo kunye nokusebenza kwe-thermal insulation kuye kwaphuculwa, ngenxa yokuphakama komzimba wesithando somlilo kunye nobubanzi obukhulu besithando somlilo, iibhodi ze-calcium silicate ziphuka ngokulula kakhulu ngexesha lokwakhiwa kwenkqubo ngenxa yobunzima babo, okubangelwa ukungaphelelanga kwe-back lining insulation kunye nemiphumo enganelisiyo yokugquma. Ngoko ke, ukwenzela ukuba kuphuculwe ngakumbi iziphumo zokugquma kwe-thermal ye-metallurgical blast furnaces kunye ne-hot blast furnaces, iimveliso ze-CCEWOOL ze-ceramic fiber (izitena / iibhodi) ziye zaba yinto efanelekileyo yokufakelwa kuzo.

Uhlalutyo lwemisebenzi yobuchwephesha yee-ceramic fiberboards:

I-CCEWOOL iiplanga ze-ceramic fiberboards zamkela umgangatho ophezulu we-AL2O3 + SiO2 = 97-99% weefayili njengezinto eziluhlaza, ezidityaniswe nezibophelelo ze-inorganic njengomzimba oyintloko kunye nezihluzi eziphezulu kunye nezongezo. Zenziwa ngokushukumisa kunye nokucofa kunye ne-vacuum suction filtration. Emva kokuba iimveliso zomisiwe, zicutshungulwa ngoluhlu lwezixhobo zokusebenza ukuze zigqibezele iinkqubo zokucubungula, ezifana nokusika, ukugaya, kunye nokugaya ukuqinisekisa ukuba ukusebenza kwemveliso kunye nokuchaneka kwe-dimensional kwizinga elihamba phambili lamazwe ngamazwe. Iimpawu zabo eziphambili zobugcisa ziquka:
a. Ukucoceka kweekhemikhali eziphezulu: iqulethe i-97-99% i-oxides ephezulu yokushisa efana ne-Al2O3 kunye ne-SiO2, eqinisekisa ukuxhathisa ukushisa kweemveliso. I-CCEWOOL ye-ceramic fiberboards ayinakuthatha indawo yeebhodi ze-silicate ze-calcium njengendawo yodonga lwesithando somlilo, kodwa isetyenziswe ngokuthe ngqo kumphezulu oshushu weendonga zomlilo ukubaxhobisa ngokugqwesa ukuxhathisa ukhukuliseko lomoya.
b. I-conductivity ephantsi ye-thermal kunye nemiphumo emihle yokufakelwa kwe-thermal: Ngenxa yokuba le mveliso yimveliso ye-CCEWOOL ye-ceramic fiber eveliswa yinkqubo ekhethekileyo yokuvelisa eqhubekayo, inomsebenzi ongcono kunezitena zomhlaba ze-diatomaceous zendabuko, iibhodi ze-calcium silicate kunye nezinye izinto ezidibeneyo zokuxhasa i-silicate kwi-conductivity ephantsi ye-thermal, imiphumo engcono yokugcina ukushisa, kunye nemiphumo ebalulekileyo yokonga amandla.
c. Amandla aphezulu kwaye kulula ukuyisebenzisa: Iimveliso zinamandla aphezulu kunye nokuguquguqukayo kwaye zizinto ezingenasiphelo, ngoko ke zihlangabezana ngokupheleleyo neemfuno zezinto ezilukhuni zomqolo. Zingasetyenziswa kuzo naziphi na iiprojekthi zokugquma ezineemfuno zamandla aphezulu, endaweni yemathiriyeli yengubo yasemva yeengubo okanye iifeelings. Okwangoku, i-CCEWOOL ye-ceramic fiberboards esetyenzisiweyo inemilinganiselo yejometri echanekileyo kwaye inokunqunyulwa kwaye iqhutywe ngokuthanda. Ulwakhiwo lulungele kakhulu, olusombulula iingxaki ze-brittleness, fragility kunye nesantya esiphezulu somonakalo wokwakhiwa kweebhodi ze-calcium silicate. Banciphisa kakhulu ixesha lokwakha kwaye banciphise iindleko zokwakha.
Isishwankathelo, i-CCEWOOL iiplanga ze-ceramic fiberboards eziveliswe ngokwenziwa kwe-vacuum azinayo ipropathi egqwesileyo yomatshini kunye nemilinganiselo yejometri echanekileyo, kodwa igcina iimpawu ezigqwesileyo zezixhobo zokugquma ubushushu. Ziyakwazi ukufaka iibhodi ze-calcium silicate kwaye zisetyenziswe kwiindawo zokugquma ezifuna ukuqina kunye nokuzimela kunye nokumelana nomlilo.
