Heat-resistant conveyor belt is a kind of high-temperature material used in metallurgy, construction and other industries to transport sinter, coke and cement clinker.
1. Choosing a suitable belt depends not only on the thermal strain but also on the chemical mechanical stress;
2. The temperature of the material to be conveyed and the surface temperature of the belt vary according to the composition, properties, surface structure and particle size of the material, such as when the temperature of the bulk material is 150 ° C (coke or sintered ore) and the contact area with the belt In hours, the surface temperature of the tape can be maintained at 60 to 80 °C. However, when conveying cement powder, the difference between the temperature of the material and the surface temperature of the belt is small;
3. The life of the heat-resistant conveyor belt is greatly affected by the surface temperature of the tape, and it affects the cover rubber and the core delamination. Therefore, when selecting the tape, it is extremely important to consider the surface temperature of the tape, as well as the ambient temperature and the tape. Whether it can be fully cooled when returning; belt speed and center distance are all worth noting;
4, thicker cover rubber is an important condition to ensure a longer life of the tape, we recommend the thickness of the cover rubber of the fabric core heat-resistant tape: the upper cover 6 ~ 8mm, the lower cover 2 ~ 4mm.
