Abstract

To further improve the oxidation-resistance of materials and reduce the cost of grid plates in grate-kiln, a new kind of heat-resistant grid plate was developed. The microstructure of this grid plate with a life more than 18 months was studied by XRD, SEM and EDS techniques. The results show that high hardness, high intensity and good impact property make the new kind of heat-resistant grid plate and its oxide film have a higher resistance to deformation and abrasion at 900-1000°C. Besides, small grain size is beneficial to form a complete protective oxide film. The oxide film composed of SiO₂ layer, Cr₂O₃ layer and Fe₂O₃ layer is rather thin and bonds closely with the backing. The forming of the chemical stable nickel-rich layer increases the density of Cr₂O₃ layer.
