Fire-resistant steel cord converyor belt
1.Configuration
The fire-resistance steel cord conveyor belt is using the higher strength,less elongation galvanized steel cord.which top and bottom surface are covered with fire resistance anti-static rubber.The configuration is sane as the general used steel cable cord conveyor belt.
2.Application
Fire-resistance steel cord conveyor belt is suitable for the area of fire prevention,explosion-proof,and of spontaneous comvustion and firing easily,which is high strict fire alarm,The belt is suitable for conveying materials at the occasion of long distance,high span,large load,and high strengh.
