Technical details and manufacturing context for Heat-resistant Conveyor Belt

Definition
The heat-resistant conveyor belt is a critical component of the Slag Cooling Conveyor system, engineered to continuously transport hot slag from furnaces or processing units to cooling areas. It operates under extreme thermal conditions, preventing material degradation and maintaining structural integrity during the slag handling process. The belt is constructed with a heat-resistant rubber compound, steel cord reinforcement, and fiberglass fabric, offering resistance to melting, deformation, and excessive wear when exposed to high-temperature materials. Available in standard widths from 500 to 2400 mm, lengths from 50 to 500 m per roll, and thicknesses from 8 to 25 mm, the belt can be customized to fit specific conveyor layouts. Its working temperature range is -40°C to 200°C continuously, with peaks up to 250°C, and cover rubber grades T1 to T3 correspond to maximum continuous temperatures of 100°C, 150°C, and 200°C respectively. The belt's tensile strength ranges from 10 to 25 MPa, elongation at break from 300% to 500%, and abrasion loss is ≤150 mm³, ensuring durability in abrasive slag handling. Carcass materials include EP, NN, or steel, with 2 to 6 plies depending on tensile strength and width. The approximate weight is 10 to 40 kg/m², and the minimum pulley diameter ranges from 200 to 800 mm, depending on belt construction and tension. These specifications align with ISO 15236-1 for belt dimensions and carcass, ISO 4195 for temperature resistance and cover grades, ISO 37 for tensile and elongation testing, and ISO 4649 for abrasion testing. However, all values are reference ranges; the actual model must be verified with the manufacturer or supplier for specific application requirements. The belt is designed for use in basic metal manufacturing, particularly in slag cooling systems, and is not intended for other high-temperature applications without proper evaluation.
Working Principle
The belt moves continuously on rollers, carrying hot slag along the conveyor path. Its heat-resistant properties prevent melting, deformation, or excessive wear when exposed to high-temperature materials, ensuring reliable transport through the cooling stages. The belt's construction, including heat-resistant rubber covers and reinforcing carcass, maintains structural integrity under thermal stress. The continuous movement allows for steady material flow, while the belt's design accommodates the thermal expansion and contraction that occurs during operation. Proper tensioning and alignment are essential to prevent premature failure. The belt's performance depends on the operating temperature, material characteristics, and conveyor design. Regular inspection for cover wear, cracking, or delamination is necessary to ensure safe operation. The belt is not designed to handle materials above its rated temperature limits, and exceeding these limits can cause irreversible damage.

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Thermal degradation and delamination
Cause: Exposure to temperatures exceeding the belt's rated heat resistance, causing breakdown of rubber compounds and separation of plies or covers from the carcass.
Edge wear and longitudinal tearing
Cause: Misalignment, tracking issues, or material spillage leading to friction against conveyor structure, compounded by heat-induced material embrittlement.
Maintenance Indicators
  • Visible surface cracking, blistering, or glazing indicating thermal overexposure
  • Audible squealing or irregular noise during operation suggesting tracking problems or excessive friction
Engineering Tips
  • Implement infrared temperature monitoring at critical points to ensure operating temperatures remain within the belt's specified range, preventing thermal degradation.
  • Regularly inspect and adjust belt tracking systems and install effective scrapers/cleaners to prevent material buildup and edge wear.
