Usage
Heat resistant steel cord conveyor belt is a special conveyor belt with steel cord as the skeleton and
high temperature resistance. It has high strength, durability and
stability, can work normally in high temperature environment, and
is widely in steel, metallurgy and other industries. When selecting
and using, heat resistant steel cord conveyor belt is necessary to pay attention to the working environment
temperature and load requirements, and do installation and
maintenance to ensure its normal operation.
Characteristics
Developed new structure carcass materials will reduce the strength
loss of heat aging during running, and thus will extend the working
life.
The cover uses superior ethylene-propylene rubber or halogenate
rubber which will enhance the high temperature resistant property
of the rubber and reduce the loss of heat aging.
