Grate Bar is the core vulnerable component of a cement clinker grate cooler. It is mainly used to support high-temperature clinker (800-1400°C), realize clinker transportation through reciprocating motion, and ensure uniform cooling air to quickly cool clinker and recover waste heat .

Core Functions 

1. Load-bearing & Support :Bears the weight of high-temperature clinker, withstands severe impact and thermal shock .

2. Air Distribution & Cooling :The gaps between grate bars allow cooling air to pass through, rapidly reducing clinker temperature from over 1300°C to below 100°C .

3. Clinker Conveyance :Cooperates with fixed and moving grate bars to push clinker move forward step by step .

Structural Types 

1. Fixed Grate Bar

Stationary installation, used to support clinker and form ventilation gaps .

2. Moving Grate Bar

Reciprocating motion driven by a transmission mechanism to push clinker forward .

3. Integral Grate Plate

Integrated block structure, widely used in 5th-generation grate coolers, with uniform air distribution and high structural strength .

Manufacturing Process 

1. Smelting :Intermediate frequency induction furnace smelting, strict control of alloy composition .

2. Casting :VRH vacuum casting /lost foam casting, ensuring dense internal structure .

3. Heat Treatment:Quenching + tempering, improving hardness and toughness .

4. Precision Machining :Drilling, cutting, grinding to ensure dimensional accuracy .

Product Advantages 

Superior High-Temperature Resistance :No deformation or oxidation failure under long-term high temperature .

 Excellent Wear Resistance :Low wear loss, reducing replacement frequency .

 Strong Thermal Shock Resistance :Resists cracking caused by rapid heating and cooling .

High Dimensional Accuracy :Good matching with equipment, low air leakage rate .

Customization Support :Customizable based on drawings (including dimensions, material, processing requirements, etc.)
