This product is widely applied in metallurgy building materials, casting and other departments for delivering sintered ore, heat coke, cement, slag, hot castings, etc.
1. Pure cotton canvas or other materials are used as casing ply and the covering layer is made of the rubber materials with excellent heat-resistant quality.
2. Product structure: one kind is same to ordinary conveyor belt the other kind is adding one layer of thermal-protective coating between covering layer and casing ply.
According to different testing temperature:
T1type: able to stand a testing temperature of ≤100℃
T2type: able to stand a testing temperature of ≤125℃
T3type: able to stand a testing temperature of ≤150℃
T4type: able to stand a testing temperature of ≤175℃
