Waa maxay faa’iidooyinka lebenka refractory?

Laydhka dib-u-milicsiga waa in lagu qaso hal ama in ka badan oo dareere ah habka wax soo saarka si ay u yeeshaan dareere xooggan. Lebenka dib-u-celinta waxaa laga sameeyaa isku-daryo kala duwan ama isku-dar ah ama noocyo kala duwan oo xirmo ah, taas oo ka dhigaysa waxqabadkooda mid aan habooneyn. Astaamaha lebenka refractory waa sida soo socota:

Xoog cadaadis: qaado xoog cadaadis weyn; heerkulka jilcinta culeyska: sidoo kale loo yaqaan heerkulka curyaaminta bilowga ah ee culeyska heerkulka sare, cabbirkan waa mid aad muhiim u ah, oo calaamad u ah iska caabbinta heerkulka sare ee walxaha; Heerka beddelka toosan: sidoo kale loo yaqaan wareejinta khadka xukunka ama khadka hadhaaga Kala-guurka waxa loola jeedaa isbeddelka ballaadhinta mugga iyo foosha ee hoos yimaada isbeddelka heerkulka isku midka ah. Haddii ballaarinta iyo foosha ay isku mid yihiin mar kasta, waxaan ku qeexnaa heerka beddelka toosan sida 0.

Cufnaanta cufnaanta: qaybta mugga cutubka, cufnaanta sare, cufnaanta cagaha wanaagsan, xoogga sare, laakiin heerkulka sare ee kuleylka; porosity muuqata: ma jiraan shuruudo faahfaahsan, laakiin soo-saaruhu waa inuu si adag u xakameeyaa porosity-ka muuqda. Dhanka kale, foorno kastaa maaha oo kaliya hal leben oo dib u celin ah, taas oo u baahan leben kala duwan oo la isku qurxiyo si loo isticmaalo midba midka kale. Lebenka refractory ee ay soo saartay shirkadeena waxay leedahay iska caabin dabka sare leh, alkali wanaagsan iyo caabbinta birta. Waa leben refractory heerka sare ah.
