Premium Cooler Grate Plates

Product Name: High-Temperature Heat-Resistant Cooler Grate Plates for Cement Kiln Lines

Description:

Engineered to withstand the most punishing thermal and mechanical environments, our Cooler Grate Plates deliver exceptional reliability for cement plant clinker cooling systems. Positioned directly at the discharge end of the rotary kiln, grate plates must endure severe thermal shocks from red-hot clinker (up to $1400^\circ\text{C}$) combined with high-pressure cooling air blasts.

Manufactured using premium-grade heat-resistant alloy steel (high Nickel and Chromium profiles), our grate plates are optimized to prevent thermal cracking, warping, and high-temperature oxidation. Whether you utilize a cross-bar cooler, pendulum cooler, or traditional grate cooler, our replacement plates ensure optimal air distribution, uniform cooling efficiency, and an extended service life.

Common Material Grades We Offer:

We precisely select the alloy composition based on the temperature zones of your grate cooler:

• High-Temp Zone (Entry): Cr25Ni20 (310S / SCH22) / Cr28Ni48W5 – Offers ultimate scaling resistance and creep strength up to $1150^\circ\text{C} – 1200^\circ\text{C}$.

• Mid-Temp Zone: Cr25Ni12 (309 / SCH13) / ZG40Cr25Ni20Si2 – Provides balanced structural strength and great thermal fatigue resistance.

• Low-Temp Zone (Exit): Cr13 / High Chromium Steel – Optimized for cost efficiency and high abrasion resistance against cooled, hardened clinker.

Key Technical Highlights:

• Precision Airflow Design: Clean, burr-free air slots and holes guarantee uniform blast distribution, eliminating clinker red rivers and improving heat recovery.

• 100% OEM Compatibility: Perfectly interchangeable with major global grate cooler brands, including FLSmidth® (Cross-Bar), Claudius Peters®, IKN®, ThyssenKrupp (Polytrack)®, and Fons Technology®.

• Advanced Anti-Warping Casting: Our strict heat treatment and structural engineering eliminate residual internal stresses, preventing the plates from bending or lifting during operation.
