High temperature resistant conveyor belt ST630 Special Conveyor Belts
High temperature resistant conveyor belt is a conveyor belt used to transport high temperature materials.
1. Classification
Heat-resistant conveyor belts are divided into ordinary
heat-resistant belts and strong heat-resistant conveyor belts. The
strength layer of ordinary heat-resistant belts is polyester cotton
canvas (CC56), and the strength layer of strong heat-resistant
belts is EP (specifically, it is divided into EP100 and EP150.
EP200, EP250, EP300, EP350, EP400, EP450, EP500, etc.).
2. Purpose
It is mainly used in metallurgy, construction and other industries
to transport high-temperature materials such as sinter, coke,
cement clinker, etc. The material temperature does not exceed 800℃,
and the belt surface temperature does not exceed 220℃. Features:
Use EPDM rubber as the covering layer, and use domestic special
high-temperature resistant canvas as the skeleton material. The
unique formula design solves the key problems of high saturation of
ethylene propylene rubber, poor adhesion, and low interlayer
adhesion. . It has the characteristics of light belt body, long
life (about 2-4 times) and good heat resistance.
The implementation of the "Conveyor Belt with Rubber or Plastic
Covering Layer of General Purpose Fabric Core Conveyor Belt"
standard, this standard adopts the draft international standard
ISO/FDIS14890-1999 standard
The heat-resistant conveyor belt is made of multi-layer rubber
cotton canvas (poly-cotton cloth) or polyester canvas covered with
high-temperature or heat-resistant rubber and bonded together by
high-temperature vulcanization. It is suitable for conveying hot
coke, cement, and slag below 175°C. And hot castings, etc.
1) The specifications are the same as ordinary conveyor belts.
2) The product implements the HG2297-92 standard.
3). Heat-resistant conveyor belts can be divided into four types:
Type I: It can withstand test temperature not greater than 100℃,
the highest short-time operating temperature is 150℃, code T1.
Type Ⅱ: It can withstand the test temperature of not more than
125℃, the maximum short-time operating temperature is 170℃, and the
code is T2.
Type Ⅲ: It can withstand the test temperature of not more than
150℃, the highest short-time operating temperature is 200℃, and the
code is T3.
Type IV: Can withstand test temperature not greater than 175℃,
maximum short-time operating temperature 250℃, code T4.
