Uyilo kunye noTshintsho lwefayibha yomaleko wokwambathisa i-Ironmaking Blast Furnaces kunye nee-Hot-blast furnaces
Intshayelelo kwisakhiwo sokuqala sokufakelwa kwe-insulation yee-blast furnitures kunye nee-hot-blast furnitures:
Isithando somlilo esiqhumayo luhlobo lwesixhobo sobushushu esinesakhiwo esintsonkothileyo. Sisixhobo esiphambili sokwenza intsimbi kwaye sineengenelo zokuvelisa imveliso enkulu, imveliso ephezulu, kunye neendleko eziphantsi.
Ekubeni ubushushu bokusebenza kwenxalenye nganye yesithando somlilo esiqhumayo buphezulu kakhulu, kwaye inxalenye nganye ichaphazeleka ziimpembelelo zoomatshini, ezifana nokungqubana kunye nefuthe lokuwa kwetshaja, uninzi lwezithinteli zobushushu obuphezulu zisebenzisa izitena zokukhanya ezishushu ze-CCEFIRE eziza nobushushu obuphezulu bokuthambisa phantsi komthwalo kunye namandla amahle oomatshini obushushu obuphezulu.
Njengenye yezixhobo eziphambili ezincedisayo zesithando somlilo esiqhumayo, isithando somlilo esishushu sibonelela ngesithando somlilo esishushu esishushu esishushu esishushu esishushu esishushu esishushu esishushu esishushu esishushu esishushu esishushu esishushu esishushu esishushu esishushu esishushu esishushu ngokusebenzisa ubushushu obuvela kwisithando somlilo esiqhumayo kunye neziphumo zokutshintshiselana kobushushu zelattice yezitena. Ekubeni inxalenye nganye ineempendulo zobushushu obuphezulu zokutsha kwegesi, ukukhukuliseka kothuli oluziswa yigesi, kunye nokukhuhla igesi eshushu, ii-refractories zomphezulu oshushu zihlala zikhetha izitena zokuthintela ukukhanya ze-CCEFIRE, ikhonkrithi engatshisi ubushushu, izitena zodongwe, kunye nezinye izinto ezinamandla oomatshini.
Ukuze kuqinisekiswe ngokupheleleyo iziphumo zokugquma ubushushu be-lining ye-furnace, kulandela imigaqo yokukhetha izixhobo ezithembekileyo ngobuchwepheshe, ezingabizi kakhulu nezifanelekileyo, i-lining yomphezulu oshushu osebenzayo we-blast furnace kunye ne-hot blast furnace yayo idla ngokukhetha izixhobo zokugquma ezinomoya ophantsi wobushushu kunye nokusebenza kakuhle kokugquma ubushushu.
Eyona ndlela yendabuko kukukhetha iimveliso zebhodi ye-calcium silicate, ezinale ndlela ikhethekileyo yokukhusela ubushushu: izitena zokukhanya ze-aluminium ephezulu kunye nesakhiwo sebhodi ye-silica-calcium enobukhulu bokukhusela ubushushu obumalunga ne-1000mm.
Olu lwakhiwo lwe-thermal insulation luneziphene ezilandelayo ekusetyenzisweni:
A. Izixhobo zokukhusela ubushushu zine-thermal conductivity enkulu kunye nemiphumo emibi yokukhusela ubushushu.
B. Iibhodi ze-silicon-calcium ezisetyenziswa kumaleko omqolo zinokwaphuka lula, zenze imingxunya emva kokuba ziphukile, kwaye zibangele ukulahleka kobushushu.
C. Ukulahleka okukhulu kokugcinwa kobushushu, okubangela inkunkuma yamandla.
D. Iibhodi ze-calcium silicate zifunxa amanzi ngamandla, kulula ukuziqhekeza, kwaye azisebenzi kakuhle xa zakhiwe.
E. Ubushushu bokusetyenziswa kweebhodi ze-calcium silicate buphantsi kwi-600℃
Izixhobo zokuthintela ubushushu ezisetyenziswa kwi-blast furnace kunye ne-hot blast furnace kufuneka zibe nokusebenza kakuhle kwe-thermal insulation. Nangona i-thermal conductivity yeebhodi ze-calcium silicate iphantsi kuneyezitena ezirhabaxa kwaye ukusebenza kwe-thermal insulation kuphuculwe, ngenxa yokuphakama komzimba we-furnace enkulu kunye nobubanzi obukhulu be-furnace, iibhodi ze-calcium silicate ziyaphuka lula ngexesha lenkqubo yokwakha ngenxa yokuba zibuthathaka, nto leyo ebangela ukuba i-back lining insulation ingaphelelanga kunye neziphumo ze-insulation ezingonelisiyo. Ke ngoko, ukuze kuphuculwe ngakumbi iziphumo ze-thermal insulation zee-metallurgical blast furnace kunye nee-hot blast furnace, iimveliso ze-CCEWOOL ceramic fiber (izitena/iibhodi) ziye zaba zezona zinto zifanelekileyo ze-insulation kuzo.
Uhlalutyo lwemisebenzi yobugcisa yeebhodi ze-ceramic fiberboards:
Iibhodi zefayibha ze-ceramic ze-CCEWOOL zisebenzisa iifayibha ze-AL2O3+SiO2=97-99% ezikumgangatho ophezulu njengezinto eziluhlaza, zidityaniswe nezihlanganisi ezingaphiliyo njengomzimba oyintloko kunye nezizalisi kunye nezongezo ezinobushushu obuphezulu. Zenziwa ngokuxubha kunye nokucoca kunye nokufunxa nge-vacuum. Emva kokuba iimveliso zomile, zicutshungulwa ngothotho lwezixhobo zomatshini ukuze kugqitywe iinkqubo zokucubungula, ezinje ngokusika, ukugaya, kunye nokubhoboza ukuqinisekisa ukuba ukusebenza kwemveliso kunye nokuchaneka kobukhulu kukwinqanaba eliphambili lamazwe ngamazwe. Iimpawu zazo zobugcisa eziphambili ziquka:
a. Ubumsulwa obuphezulu beekhemikhali: buqulethe i-97-99% yee-oxides zobushushu obuphezulu ezifana ne-Al2O3 kunye ne-SiO2, eqinisekisa ukumelana nobushushu kweemveliso. Iibhodi ze-ceramic ze-CCEWOOL azinakuthatha indawo yeebhodi ze-calcium silicate njenge-furnace eludongeni, kodwa zingasetyenziswa ngqo kumphezulu oshushu weendonga ze-furnace ukuze zixhotyiswe ngokumelana okuhle nokukhukuliseka komoya.
b. Ukuqhuba okuphantsi kobushushu kunye neziphumo ezilungileyo zokuthintela ubushushu: Ngenxa yokuba le mveliso yimveliso yefayibha yeseramikhi ye-CCEWOOL eveliswa yinkqubo ekhethekileyo yemveliso eqhubekayo, isebenza ngcono kunezitena zomhlaba zendabuko ze-diatomaceous, iibhodi ze-calcium silicate kunye nezinye izinto ezixhasayo ze-silicate ezidityanisiweyo kwi-conductivity yayo ephantsi kobushushu, iziphumo ezingcono zokugcina ubushushu, kunye neziphumo ezibalulekileyo zokonga amandla.
c. Amandla aphezulu kwaye kulula ukuyisebenzisa: Ezi mveliso zinamandla aphezulu okuxinzelela kunye nokugoba kwaye azinazo izinto ezibuthathaka, ngoko ke ziyahlangabezana ngokupheleleyo neemfuno zezinto eziqinileyo zomqolo. Zingasetyenziswa kuyo nayiphi na iprojekthi yokufudumala eneemfuno ezinamandla aphezulu, endaweni yezinto ezingasemva zomqolo zeengubo okanye iifelts. Okwangoku, ii-fiberboards ze-ceramic ze-CCEWOOL ezicutshungulweyo zinemilinganiselo echanekileyo yejometri kwaye zinokunqunyulwa kwaye zicutshungulwe ngokuthanda kwazo. Ulwakhiwo lulula kakhulu, olusombulula iingxaki zokubuthathaka, ubuthathaka kunye nesantya esiphezulu somonakalo wokwakha kwiibhodi ze-calcium silicate. Zinciphisa kakhulu ixesha lokwakha kwaye zinciphisa iindleko zokwakha.
Ngamafutshane, iibhodi ze-ceramic ze-CCEWOOL ezenziwe nge-vacuum forming azinazo nje kuphela iimpawu ezintle zoomatshini kunye nobukhulu obuchanekileyo bejometri, kodwa zikwagcina iimpawu ezintle zezinto zokukhusela ubushushu ezine-fibrous. Zingathatha indawo yeebhodi ze-calcium silicate kwaye zisetyenziswe kwiindawo zokukhusela ezifuna ukuqina nokuzixhasa kunye nokumelana nomlilo.
Indlela yokusetyenziswa kweebhodi zefayibha zeseramikhi kwiifeni zokuqhuma ezenziwe ngentsimbi kunye neefeni zokuqhuma ezishushu
Indlela yokusetyenziswa kweebhodi ze-ceramic ze-CCEWOOL kwii-ovens ze-ironmaking blast isetyenziswa kakhulu njengenkxaso yezitena ze-silicon carbide refractory, izitena zodongwe ezikumgangatho ophezulu okanye izitena ze-alumina refractory eziphezulu, endaweni yeebhodi ze-calcium silicate (okanye izitena zomhlaba ze-diatomaceous).
Ukusetyenziswa kwiifurniture zokuqhuma ezenziwe ngentsimbi kunye neefurniture zokuqhuma ezishushu
Iibhodi ze-ceramic ze-CCEWOOL zingathatha indawo yesakhiwo seebhodi ze-calcium silicate (okanye izitena zomhlaba ze-diatomaceous), kwaye ngenxa yeenzuzo zazo, ezinje ngokuhambisa ubushushu obuphantsi, ubushushu obuphezulu obusetyenziswayo, ukusebenza kakuhle kwe-machining, kunye nokungafunxwa kwamanzi, zisombulula ngempumelelo iingxaki ezazikho kwisakhiwo sokuqala, umzekelo, iziphumo zokuthintela ubushushu obuphantsi, ukulahleka kobushushu okukhulu, izinga eliphezulu lomonakalo weebhodi ze-calcium silicate, ukusebenza kakubi kolwakhiwo, kunye nobomi obufutshane benkonzo ye-insulation lining. Zifumene iziphumo ezilungileyo kakhulu zokusetyenziswa.
