Waa maxay farqiga u dhexeeya lebenkii alwaax ahaanta ku shaqeeya iyo leben dahaarka?

Shaqada ugu weyn ee lebenka dahaarka kulaylka waa in la diirimaadyo oo la yareeyo luminta kulaylka. Lebenka dahaarka kulaylka guud ahaan si toos ah uma taabtaan ololka, halka lebenka refractory guud ahaan si toos ah u taabto ololka. Lebenka dib-u-celinta ayaa inta badan loo isticmaalaa si ay ugu adkeystaan ​​gubashada ololka. Guud ahaan waxa loo qaybiyaa laba nooc, kuwaas oo kala ah refractories qaabaysan iyo refractories qaabaysan. Waxyaalaha refractory ee aan qaabaysan: sidoo kale loo yaqaan castable, waa granul budada ah oo isku dhafan oo ka kooban noocyo kala duwan oo isku-dar ah ama isku-ururin iyo hal ama in ka badan oo xirayaasha ah. Waa in lagu qaso hal ama ka badan oo dareere ah oo lagu qaso si siman inta lagu jiro isticmaalka. Leh dareere xooggan. Qalabka refractory ee qaabaysan: guud ahaan waxa la sameeyay lebenka refractory, qaabkaas oo leh xeerar caadi ah, waxa kale oo si ku meel gaadh ah loogu farsamayn karaa hadba baahiyaha marka la dhisayo ama la jarayo.

Farqiga ugu weyn ee u dhexeeya lebenka dahaarka kulaylka iyo lebenka refractory waa sida soo socota:

1. Waxqabadka kuleylka kuleylka

Dareenka kulaylka ee lebenka dahaarka kulaylka guud ahaan waa 0.2-0.4 (celcelis ahaan heerkulka 350 ± 25 ° C) w / mk, halka kulaylka conductivity ee leben refractory uu ka sarreeyo 1.0 (celceliska heerkulka 350 ± 25 ° C) w / mk, iyo leben dahaarka kulaylka waa la heli karaa. Waxqabadka dahaarka kulaylka ee leben Refractory aad ayuu uga fiican yahay kan lebenka refractory.

2. Dib -u -dhac

Nadiifinta lebennada dahaarka ayaa guud ahaan ka hooseeya 1400 darajo, halka dib u soo celinta lebennada refractory ay ka sarreeyaan 1400 darajo.

3. Cufnaanta

Lebenka dahaarka guud ahaan waa walxo dahaadh-fudud ah, cufnaanta 0.8-1.0g/cm3 iyo cufnaanta lebennada celinaya ayaa asal ahaan ka sarreeya 2.0g/cm3.

Guud ahaan, lebenka refractory waxay leeyihiin xoog farsamo oo sarreeya, nolol adeeg oo dheer, xasilooni kiimikaad oo wanaagsan, fal-celin kiimiko ah oo alaab ah iyo iska caabin heerkul sare oo wanaagsan. Heerkulka iska caabinta kulaylka sare wuxuu gaari karaa 1900 ℃. Waxay si gaar ah ugu habboon tahay foornooyinka isbeddelka heerkulka sare iyo kuwa hooseeya, dib-u-habeeyayaasha, hydroconverters, taangiyada desulfurization iyo methanizers ee dhirta bacriminta kiimikada si ay u kala firdhiyaan gaaska iyo dareeraha, iyo taageerada, daboolka iyo ilaalinta kicinta. Waxa kale oo loo isticmaali karaa shooladaha qaraxa kulul iyo qalabka beddelka kululaynta ee warshadaha birta iyo birta.

Lebenka refractory waxay leeyihiin faa’iidooyinka cufnaanta sare, xoogga sare, xirashada caabbinta, caabbinta daxalka wanaagsan, coefficient fidinta kulaylka hoose, hufnaan sare shiidi, qaylada hoose, nolosha adeegga dheer, iyo alaabta aan wasakhayn. Waa meel wax lagu shiidi karo oo ku habboon mashiinnada wax lagu shiidi karo ee kala duwan.

Lebenka refractory aad bay uga duwan yihiin lebennada dahaarka kulaylka, iyo deegaanka isticmaalkooda, baaxadda iyo shaqadoodu waa kala duwan tahay. Qalab kala duwan ayaa loo isticmaali doonaa meelo kala duwan. Marka aanu dooranayno alaabta, waa in aan go’aan ka gaarnaa walxaha dib-u-celinta ee ku habboon isticmaalkeena marka loo eego xaaladdayada dhabta ah.
