Calaamadaha Alaabta

Qalabka NiCr8020 oo leh lambarka agabka 2.4869 waxaa lagu dabaqaa qaab xariijimo, xaashiyo, tuubooyin iyo fiilooyin loogu talagalay qaybaha dhismaha foornada iyo qalabka kuleyliyaha.

Waa dahaarka kuleyliyaha nikkel-chromium ee heerkulka hawlgalka ilaa 1150 °C badanaana waxa ku jira waxyaabo lagu daro dhul naadir ah si loo helo iska caabin sare oo ku timaadda oksaydhka, gaar ahaan marka la sameeyo hawlgallo isbeddel oo soo noqnoqda ama isbeddello heerkul oo ballaaran.

Iska caabbinta daxalka jawiga ee 20 °C waa mid sare ilaa heerkulka sare ee hawlgalka, iska caabbinta hawada iyo gaasaska kale ee oksijiinta ku jira iyo sidoo kale gaasaska oksijiinta ku yar ee ay ku jirto nitrogen sidoo kale waa mid sareysa, haddana way yar tahay oksaydhaynta iyo sidoo kale yaraynta gaasaska ay ku jirto baaruuddu.

Iska caabbinta kaarboonaynta waa mid aad u sareysa. Codsiga foornada korontada ee warshadaha, foornada dhalaalaysa, qalabka guryaha, kuleyliyaha kaydinta habeenkii.
