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.)
Application Scope
· Cement Industry :3rd/4th/5th-generation clinker grate coolers (core component) .
· Metallurgical Industry :Sintering machine, blast furnace auxiliary equipment .
· Power Generation :Biomass boiler, waste incineration boiler .
