In October last year, we sent a heat-resistant conveyor belt to a steelmaking plant in Canada. This heat-resistant conveyor belt has a width of 1400mm and a length of 85m. Its maximum heat resistance is as high as 175°C. 

  Heat resistant conveyor belt is a special conveyor belt that used for conveying materials in a high temperature environment and has good heat resistant performance. It is widely used in metallurgy, chemical industry, building materials and other industries with a high temperature environments which can withstand the high temperature during the conveying and processing, also keep the conveyor belt could work normally. The heat resistance performance of the heat resistant conveyor belt will be introduced from the aspects of select the material, structure design, heat resistance performance in details.

  Firstly, the material selection of heat resistant conveyor belt plays a decisive role to its heat resistance performance. The heat resistant conveyor belt usually used the high temperature resistance materials such as polytetrafluoroethylene (PTFE), silicone, fluororubber, etc. These materials have good high temperature resistance performance and are able to maintain the material conveyor belt operate normally in a high temperature environment. Among them, the polytetrafluoroethylene as the material has low friction coefficient, and good anti corrosion resistance and high temperature resistance performance which are widely used in the manufacture of heat resistant conveyor belt.

  Secondly, also the structure design of the heat resistant conveyor belt plays an important role in its heat resistant performance of heat resistant conveyor belt. Heat resistant conveyor belt usually adopt a laminated structure and the combination of multiple layers of materials can improve the heat resistant performance. Through the appropriately design the structure can reduce the conduction and the accumulation of heat and improve the using life of the heat resistant conveyor belt. In addition, the structure design could consider to be added fire protection, flame retardant and other functions to improve performance.

  Thirdly, the heat resistance of the heat resistant conveyor belt is closely related to its working temperature range. Different types of heat resistant conveyor belt has different operating temperature ranges. It is important to choose the appropriate heat resistant conveyor belt according to the actual temperature in working environment. Generally, the material named polytetrafluoroethylene of the heat resistant conveyor belt could work normally between -70℃~260℃. But, the silicon of the heat resistant conveyor belt can withstand higher temperature which can reach more than 300℃.

  In addition, the anti wear resistance of the heat resistant conveyor belt is closely related to its heat resistance. Due to the property of the materials under a high temperature and the influence of operating methods. The heat resistant conveyor belt usually has higher anti wear resistance. Generally speaking, the surface of the heat resistant conveyor belt could add anti wear layer in order to improve its anti wear performance to extend the using life.
