Échec ya échec ya grille .

Na production ya matériel ya grille, ba entreprises misusu esalelaka alliage acier, misusu esalelaka fer ya coulée ductile, misusu esalelaka froid dur cast fer na fer ya chrome ya likolo. Méthode ya procédé kobanda na casting ya sable ya mabele ya lima,kopanzana na die na procédé ya coulée ya sable oyo elatisami ezali ndenge na ndenge. Kasi uta na tendance ya développement na ba mbula oyo euti koleka, malembe malembe ezalaka na tendance ya kolimwa na die mpe na revêtu ya production ya procédé ya sable, matériel na fer ya chrome ya likolo lokola principal, qualité ya produit ebongwani, mpe vie ya service ezali soki mbula moko. Grate bar under a certain static pressure, to withstand the room temperature to about 1000℃.Periodic hot baking, at the same time to withstand oxygen, sulfur and other corrosive high temperature air flow impact, resulting in The surface of the grate strip gradually oxidation, melting and deformation, growth and even cracking, high temperature strength Figure 1 Operation process of sintering equipment When insufficient, deformation and fracture occur, resulting in Fuite to collapse ya machine ya sinterisation, oyo ezo affecter gravement ba positifs mbala mingi ebimisaka. Bomoi ya mosala ya bar ya grille ya zando ezali mingimingi pene na mbula moko. Mpo na kokitisa malamu ntalo, kokitisa ntalo na ntango ya kozanga mosala, pona bande ya grille na makoki ya makasi ya antioxydant mpe résistance ya corrosion.
