High temperature steel wire conveyor belt is made of steel vertical and horizontal, steel mesh surface galvanized or copper, steel mesh in the upper and lower surface covered with rubber layer, the transport of high temperature materials, the overall surface does not delamination, the use of performance than hierarchical Heat-resistant conveyor belt more reliable.

Precautions for use

    With the conveyor belt in the popularization of industrial production, multi-species, high-performance, lightweight, multi-functional, long life is the manufacturer of several aspects of concern. In industrial production, the proper use of conveyor belt is particularly important, conveyor belt in use should pay attention to the following:

1. To avoid roller covered by the material, resulting in rotation is not working to prevent leakage of material between the roller and tape in the tape, pay attention to the active part of the conveyor belt lubrication, but not oil conveyor belt;

2. To prevent the conveyor belt load start;

3. Conveyor belt deviation occurs, should take timely measures to correct;

4. When the conveyor belt is found to be damaged, the artificial cotton should be repaired in time so as not to expand.

5. To avoid the conveyor belt by the rack, pillar or block material block, to prevent break-breaking rip.

Key Features

      This type of conveyor belt is mainly used for metallurgical, building materials, casting, coking, chemical and other industries conveying sintered ore, coke, cement, fertilizer and other high-temperature solid materials, with the required heat resistance. Heat-resistant conveyor belt heat resistance and service life depends on the cover layer and core with the heat resistance. Generally good heat resistance of rubber such as: styrene butadiene rubber, butyl rubber, ethylene propylene rubber as the main compound to heat, heat shrink small polyester-cotton, polyester-Jin canvas with a core. Heat-resistant conveyor belt according to the test temperature is divided into four grades. T1: Test temperature at which heat resistance is not more than 100C; T2: Test temperature at which heat resistance is not more than 125C; T3: Test temperature at which the heat resistance is not greater than 150C; T4: Test for heat resistance not exceeding 175C temperature. Heat-resistant conveyor belt strength specifications and width of the same specifications and ordinary conveyor belt. Example of tape marking: 200 1200 EP 5 1000 8 + 3 T2 This tape has a length of 200 m and a width of 1200 mm. The tape has five layers of EP canvas, the strength specification is 1000N / mm, the upper and lower cover layers are 8mm and 3mm respectively, Can be resistant to heat is not greater than 125 ℃ test temperature. The implementation of such products GB / T 20021-2005 "canvas heat-resistant conveyor belt," the national standard. In order to meet the higher use of temperature, some manufacturers have also developed the ability to withstand higher temperature levels of heat-resistant conveyor belt and the burning of high-temperature conveyor belt, usually in the overlay compound added flame retardant insulation, anti-burning Etching agent, heat agent, etc., in order to improve the high-temperature anti-erosion properties of tape.

Features & Benefits:
1》、Heat-resistant cover resists cracking and hardening
heat-resistant belt performs over the long run, retaining its flexibility despite punishing condition and loads. Less cracking and hardening translates into longer life and reduced replacement costs. Heat-resistant belt compound retains its Heat-resistant qualities after prolonged exposure to 200℃ hot loads.
2》、High-temperature resistance to tearing and abrasion.
Load after load, huayue belt stands up to prolonged exposure. This reduced maintenance and downtime helps lower overall operating costs.
3》、High strength carcass construction 
  the carcass use steel wire or synthetic material. Synthetic carcass provides great dimensional stability and strength at high   temperatures and operating tensions up to 2000 kN/mm.
4》、The carcass with heat-resistant material 
  the apply special carcass in the heat-resistant belt, provide maximum protection when temperatures are not constant. The carcass      stand up to “hot shots”, resisting burn-through up to 538℃.
