Heat-resistant conveyor belt is mainly used for conveying high-temperature materials such as sinter, heat coke, cement clinker, hot casting and so on.
According to heat damage resulting in loss of transmission capacity with the main performance and the different heat levels, respectively, or styrene-butadiene rubber EPDM rubber cover to do; high strength and high permeability of polyester canvas or cotton canvas make a strong layer. Plastic cover on the framework can be laid between layers of glass heat-resistant fabric, to enhance the service life of heat-resistant tape. According to customer requirements, can be made into ring belt, heat-resistant temperature can reach 300 ℃.
The implementation of heat-resistant conveyor belt HG-2297-92 standard.
