Heat Resistant Conveyor Belts for Steel Mills & Cement Plants

Heat Resistant Conveyor Belt

JINFLEX heat resistant conveyor belts are designed for transporting high-temperature materials (＞60℃), widely used in steel mills (sintered ore, steel slag), cement plants (cement clinker), power stations (coke), asphalt mixing plants, and waste incineration plants—suitable for materials with temperatures up to 200℃.

Our heat resistant conveyor belts comply with China’s industrial standards (HG/T2297) and international standards, including Germany (DIN22131), the United States (RMA), Japan (JIS6369), Australia (AS1333), South Africa (SABS), and international standard (ISO4195).

Heat Resistant Conveyor Belt

Product description

The heat resistant conveyor belt adopts a "high-temperature resistant cover rubber + heat-treated carcass + heat-stable core rubber" structure, resisting thermal aging:

Heat Resistant Cover Rubber: Classified by temperature resistance (HR120/HR150/HR180/HR200/HOR), with special heat stabilizers—no cracking, hardening, or softening under high temperatures.

Carcass: Multi-ply fabric (EP/NN/CC) (special heat treatment)，reducing thermal shrinkage rate ≤1% (after 24h at rated temperature) and maintaining tensile strength.

Core Rubber: Heat-resistant core rubber with low thermal conductivity, isolating high temperatures from the carcass; adhesion strength ≥7.0N/mm at 160℃.

Back Cover Rubber: Wear-resistant back cover (Shore abrasion ≤150mm³) resists high-temperature roller friction.

Features and Benefits

■ Classified Temperature Resistance

HR120: For ≤120℃ materials (coke, sintered ore)

HR150: For ≤150℃ materials (steel slag, cement clinker)

HR180: For ≤180℃ materials (high-temperature filter residue)

HR200: For ≤200℃ materials (waste incineration residues)

HOR: For oil-containing high-temp materials (asphalt, ≤180℃)

■ Low Thermal Shrinkage

Carcass thermal shrinkage ≤1% at rated temperature, no belt length change or deviation during long-term use.

■ High Wear & Impact Resistance

Cover rubber wear rate ≤0.2mm/month (HR150 type); impact resistance ≥45kJ/m², resisting falling high-temp ore impact.

■ Long Service Life

Heat aging test (70℃×168h for D/H type, 125℃×168h for T2 type) shows tensile strength retention ≥80%, service life up to 36 months.

■ Safe Operation

Non-toxic and low-smoke cover rubber, no harmful gas release at high temperatures—meeting environmental protection requirements.
