Grid

The primary failure modes of sintering machine grate bars or grid are ablation and breakage. In order to improve the strength and corrosion resistance of the grid or grate bar in the pelletizing production line, the chain grid or grate bar and sintering machine grate bar manufacturers optimize their composition.

Appropriate amounts of Al and Si are added to the high-chromium grate to improve its oxidation resistance. In addition, an appropriate amount of B, Zr and Y are added to refine the structure, which is beneficial to the substantial improvement of the mechanical properties of the high-chromium grate. Finally, improve the application performance of high-chrome grate bars. In addition, a filter treatment process is also used in the manufacture of grate bars to reduce the number of inclusions in the casting arrangement and improve the strength, toughness and oxidation resistance of the grate bars. The high-chromium grate bars produced by our factory are used on a 450m2 large sintering machine trolley, the grate bars consume 20~30g/t, and the service life exceeds one and a half years.
