Bloc de glisseur de chaudière en acier résistant à chaleur
Njortu internasional ak jàngat moomeel
Bloc glisseur chaudière (ñu xamee ko ci gliiseur ci suufu four, gliiseur ci suufu ndox, ak pads wear) dañuy dox ci anam wu metti, lu ci melni tàngoor wu metti wu tàmbalee ci 900 degre ba 1200 degre, sargal yu diis, friksioŋ bu wéy, ak atmosphere oxidant yu dëgër. Li gëna am solo ci liggéey bi mooy mu mëna dékku tàngoor wu metti, mu mëna dékku tàngoor wu metti, mu mëna dékku wear, mu mëna dékku choc thermique, ak deformation bu néew.
Ci suuf amna jàngat bu leer ci grade alloy yiy xeex tàngoor - yiñ gëna jëfandikoo ci bloku gliiseur yu chaudière yi.
