Refractory tundish nozzles ndi ndodo zoyimitsa

Ndodo zoyimitsa: Pa tundish ya makina opitilira apo, mapulagi ophatikizika amagwiritsidwa ntchito kwambiri. Mpweya wotchinga wotchinga umatuluka pabowo laling'ono pamutu wa pulagi ndodo, zomwe zingalepheretse aluminium oxide kuti isasungidwe pafupi ndi malo osindikizira a doko lamadzi, kapena kuchepetsa kuchuluka kwake, ndikusunthira malo owunjikira pansi. Pofuna kuwonjezera moyo wa pulagi mutu atsogolere Mipikisano ng'anjo mosalekeza kuthira, pulagi mitu ndi zirconia multilayer kapena zonse zirconia pulagi ndodo ntchito pa tundish wa slab caster.
Tudish nozzles: zinthu za tundish nozzles amasankhidwa malinga ndi mtundu wa zitsulo anathira, pamene kuthira ambiri mpweya zitsulo, mungagwiritse ntchito mullite nozzle munali Al2O3 70 ~ 75%. Mukathira zitsulo zosavuta, magnesium oxide kapena zirconia nozzles zitha kugwiritsidwa ntchito. Mukathira chitsulo chachikulu cha manganese, ma aluminium apamwamba a graphite kapena zirconia nozzles angagwiritsidwe ntchito.
