Grate Bars, Plates, Pulley Idlers & Sector Gates
Sintering machines are subject to intense thermal cycling, severe abrasive wear, and heavy structural stresses during the iron-making process. Excellors designs and manufactures high-performance sintering plant equipment components, engineered to extend the operational lifespan of sinter bed assemblies while minimizing maintenance downtime.
Our Grate Bars & Grate Plates are produced using an advanced coated sand casting process. This guarantees a perfectly smooth surface finish, structural integrity with no internal pores or cracks, and high dimensional stability to prevent bending deformation during hot sinter bed operations.
We also supply high-strength Pulley Idlers (both cast and fabricated designs) that feature superior wear resistance and positive biting performance to ensure continuous material conveying. Additionally, our fabricated Sector Gates are engineered for reliable discharge control, supporting manual, hydraulic, or pneumatic operations.
Key Sintering Components
- Grate Bars & Plates: Coated sand casting process ensures smooth surface and pore-free structure.
- Dimensional Stability: Zero bending deformation under extreme heat loading.
- Pulley Idlers: Casting and fabricated variants. Outstanding wear and abrasion resistance.
- Conveying Performance: High biting performance for smooth material flow and minimal belt slip.
- Sector Gates: Fabricated assemblies supporting manual, hydraulic, or pneumatic operation.
Material Quality
Alloy Standards: Grate bars are cast using heat-resistant alloy steel grades that offer excellent oxidation and thermal shock resistance up to 1000°C.
SGP Equipment & Gas Duct Spares Replacement
Sintering Gas Plants (SGP) handle highly abrasive, hot sintering dust and exhaust gases. SGP equipment spares (including dust collecting pipelines, screw conveyors, dampers, and expansion joints) are subject to continuous abrasion. Excellors specializes in custom SGP equipment replacement, engineering heavy-duty dust collection screw feeders, sector gates, and gas duct casings designed to prolong service life.
By combining high-chrome overlays, structural steel reinforcements, and positive seal alignments, our replacement spares reduce wear-induced air leaks and minimize maintenance shutdowns in SGP ducting paths.
