Doorka ugu weyn ee leben dahaarka waa in la ilaaliyo kulaylka lana yareeyo luminta kulaylka. Lebenka dahaarka ah guud ahaan si toos ah ulama xiriiraan ololka, iyo bululiga dab-demiska ayaa inta badan si toos ah ula xiriira ololka. Qoryaha dab-damiska ayaa inta badan loo isticmaalaa in lagu adkeeyo ololka la dubay. Guud ahaan waxa loo kala qaybiyaa laba nooc, kuwaas oo kala ah walxo refractory ah oo aan qaabayn iyo qaabaysan qaabaysan.
Qalabka Dib-u-celinta ee aan qaabaysan
Maaddada dib-u-celinta ee castables waa walxo budo ah oo isku dhafan oo ka kooban isku-gyo kala duwan ama isku-ururin iyo hal ama ka badan oo xirmooyinka. Isticmaalka waa in lagu qaso hal ama in ka badan oo dareere ah, oo leh dareere xooggan.
Walxaha Refractory ee Qaabaysan
Xaaladaha caadiga ah, qaabka lebenka refractory waxay leeyihiin cabbirka caadiga ah, sidoo kale waxaa loo habeyn karaa iyadoo loo eegayo shuruudaha macaamiisha.
Farqiga ugu weyn ee udhaxeeya bulukeetiyada dahaadhka ah
1. Waxqabadka dahaarka
Dareenka kulaylka ee lebenka dahaarka guud ahaan waa 0.2-0.4 (heerkulka celceliska 350± 25 ° C) w / mk, iyo kuleylka kulaylka ee bulukeetiga ayaa ka sarreeya 1.0 waxqabadka leben dahaarka ayaa aad uga fiican lebenka dabka.
2. Refractority
Dib-u-soo-celinta lebenka dahaadhka ah ayaa guud ahaan ka hooseeya 1400 darajo, iyo dib-u-celinta lebenka refractory ayaa ka sarreeya 1400 darajo.
3. Cufnaanta
Lebenka dahaarka waa walxo dahaadh khafiif ah, cufnaanta lebennada dahaarka guud ahaan waa 0.8-1.0g/cm3 iyo cufnaanta lebennada refractory asal ahaan ka sarreeya 2.0g/cm3.
Gabagabo
Marka la soo koobo, lebenka refractory wuxuu leeyahay awood farsamo oo sare, cimri dheer oo adeeg ah, xasilooni kiimikaad oo wanaagsan, wax falcelin kiimiko ah oo maaddadu leedahay iyo iska caabin heerkul sare oo wanaagsan, iyo heerkulka ugu sarreeya ee u adkaysta wuxuu gaari karaa 1900 ° C. Lebenka refractory ayaa si gaar ah ugu habboon in loo isticmaalo beddelayaasha heerkulka hooseeya, kuwa wax beddelaya, beddelayaasha hydrogenation, taangiyada desulfurization, iyo foornooyinka methanation ee dhirta bacriminta kiimikada si ay door uga ciyaaraan firdhinta dareerayaasha gaaska, taageeridda, daboolida, iyo ilaalinta kicinta. Lebenka dab-demiska waxaa sidoo kale loo isticmaali karaa shooladaha kulul iyo qalabka beddelka kuleylka ee warshadaha birta.
Dab-damisku waxay leeyihiin faa'iidooyinka cufnaanta sare, xoogga sare, xirashada caabbinta, caabbinta daxalka wanaagsan, iskudhafka ballaarinta kulaylka hooseeya, waxtarka sare ee wax-ku-oolnimada, qaylada hoose, nolosha adeegga dheer, iyo alaabta aan wasakheynin. Waa meel-shiidid wanaagsan oo ku habboon mashiinnada wax lagu shiido ee kala duwan.
Lebenka dib-u-celinta iyo lebenka dahaadhka ah aad bay u kala duwan yihiin, isticmaalkooda deegaanka, baaxadda iyo doorkoodu isku mid maaha. Qalab kala duwan ayaa loo isticmaali doonaa meelo kala duwan. Marka la iibsanayo alaabta, waa in aan go'aansanno nooca alaabta dib-u-celinta ee ku habboon isticmaalkeena iyadoo loo eegayo xaaladdayada dhabta ah.
