Overview
Sinter machine tires are large annular components integral to sintering machines, which agglomerate fine iron ores into sinter for blast furnace use. These tires rotate on supporting rollers, carrying the weight of sintering pallets (typically 30-100 tons) while enduring temperatures up to 1,200°C. Manufactured as single castings or segmented designs, they range from 3-8 meters in diameter. Their precision engineering minimizes vibration and ensures consistent sintering bed movement, directly impacting production efficiency in steel plants.
Structure and Working Principle
The tire's cross-section features a double-flange design to secure pallet alignment, with machined grooves for drive engagement. Internally, it incorporates cooling channels or heat-resistant coatings to manage thermal stress. During operation, motor-driven pinions mesh with the tire's outer gear teeth, rotating the entire sintering strand at 1.5-3.5 m/min. The tire's hardness (typically HB 280-350) balances wear resistance and shock absorption, while its roundness tolerance (<2mm) prevents pallet slippage.
Key Features
Premium sinter tires use micro-alloyed steels with chromium-molybdenum additives for creep resistance at 400-600°C operating temperatures. Surface hardening extends service life to 5-8 years under proper maintenance. Modern designs incorporate laser-clad wear surfaces or replaceable segment teeth. Some variants include integrated temperature sensors for predictive maintenance, reducing unplanned downtime in 24/7 sintering operations.
Application Areas
Primarily used in Dwight-Lloyd type sintering machines for iron ore (90% market share), with secondary applications in non-ferrous sintering (e.g., lead, copper concentrates). Standard sizes match common machine models like 75m², 90m², or 180m² sintering areas. Recent innovations include tires for hybrid sintering-pelletizing systems and those compatible with alternative fuels like hydrogen-enriched sintering processes.
Maintenance and Precautions
Monthly inspections should check for tooth wear (>15% loss requires replacement), radial runout (>3mm indicates roller adjustment needed), and surface cracks (detectable via magnetic particle testing). Lubrication systems must use high-temperature greases (dropping point >200°C). Misalignment causes accelerated wear—annual laser alignment checks are recommended, especially after roller replacement.
B2B Procurement Guide
Leading manufacturers include CITIC Heavy Industries (China), SMS group (Germany), and Primetals Technologies. Lead times range 12-20 weeks for custom sizes. Buyers should request: 1) Material test certificates (including Charpy impact values at working temperatures), 2) On-site dimensional inspection reports, and 3) Finite element analysis (FEA) documentation for stress distribution. Consider modular designs for easier replacement. Budget 15-20% extra for premium alloys in high-sulfur flue gas environments. Many suppliers offer lifecycle cost guarantees (e.g., $/ton sinter produced).
