1、Overview
High Temperature Resistant Conveyor Belts are expertly designed to endure extreme thermal environments, enabling the safe and efficient transportation of hot materials. Engineered with advanced heat-resistant materials and innovative structures, these belts maintain mechanical integrity, resist thermal degradation, and reduce the risk of premature failure. They significantly cut maintenance costs and downtime, making them essential for industries operating under high-temperature conditions.
2、Key Applications
- Metallurgy Industry: Conveys red-hot metals, sintered ores, and hot coke, withstanding temperatures up to 1200°C during steel and iron production processes.
- Cement Manufacturing: Handles clinker, raw meal, and hot ash generated in rotary kilns and coolers, where continuous exposure to 300 - 800°C is common.
- Glass Production: Transports molten glass and hot glass products from furnaces to annealing lehrs, ensuring stable operation in the intense heat of the glass-making process.
- Power Generation: Moves hot coal ash and slag from boilers and incinerators, resisting high temperatures while maintaining belt functionality.
3、Material Technology
4、Cover Materials
- Silicone Rubber: Offers excellent resistance to high temperatures, typically performing well from -60°C to 250°C. It maintains flexibility and resilience even after prolonged exposure to heat, making it suitable for medium to high-temperature applications.
- Fluororubber (FKM): Withstands extreme heat up to 300°C and also provides good chemical resistance. Ideal for environments where both high temperatures and chemical exposure coexist, such as in certain chemical processing plants with heated operations.
- Ceramic-Coated Fabrics: Feature a ceramic layer that can shield the underlying material from temperatures exceeding 1000°C. The ceramic coating reflects heat and protects the base fabric, making these belts suitable for ultra-high-temperature applications like handling molten metals.
5、Carcass Reinforcements
- Aramid Fiber: Boasts high tensile strength and retains its mechanical properties at elevated temperatures. It provides robust support to the belt, preventing stretching and structural damage under heat and load.
- Basalt Fiber: Offers good heat resistance up to 700°C, along with excellent chemical and abrasion resistance. It is a reliable choice for high-temperature conveyor belts, especially in harsh industrial settings.

6、Features & Benefits
- Thermal Stability: Maintains shape, strength, and flexibility under continuous high-temperature exposure, ensuring reliable material transport.
- Extended Service Life: Resistant to thermal degradation, reducing the frequency of belt replacements and minimizing associated costs.
- Operational Safety: Prevents belt failures due to heat, safeguarding workers and production equipment from potential hazards.
- Versatility: Can handle a wide range of hot materials across different industries, adapting to various high-temperature operation requirements.
7、Selecting the Right Belt
- Determine Temperature Range: Accurately identify the maximum and minimum operating temperatures, including any short-term peak heat conditions.
- Assess Load and Speed: Consider the weight of the materials being transported and the conveyor's operating speed to ensure the belt has sufficient strength and durability.
- Evaluate Chemical Exposure: If the belt will come into contact with chemicals in addition to heat, choose materials with appropriate chemical resistance to prevent combined degradation.
- Check Certification: Ensure the belt meets relevant international standards for high-temperature resistance, such as ISO or ASTM requirements, for quality assurance.
8、Maintenance
- Regular Inspections: Periodically check for signs of heat-induced damage, like hardening, cracking, or discoloration, to detect issues early.
- Cleaning: Remove any accumulated debris or residue regularly, as these can retain heat and accelerate belt degradation.
- Storage: When not in use, store the belt in a cool, dry place away from direct heat sources to preserve its heat-resistant properties.
