Typically, a mesh belt is consists of stainless steel, 80 nickel-20 chromium alloy, and iron base with 30% nickel. All of these alloys which are effective to withstand high temperatures existent in a brazing furnace but still tends to oxidize easily. Also, these materials tend to carburize and become very brittle if the atmosphere is carburizing.
The most widely used brazing atmosphere includes rich exothermic gas which is typically comprised of hydrogen, carbon monoxide, moisture, carbon dioxide, or the balance nitrogen. When such atmospheres are dry, reducing and carburizing, belt damage is even more rapid. Consequently, atmospheres which are too oxidizing, reducing or carburizing negatively affect the life of conveyor belts.
Common mesh belt problems & defects
Broken edge
Edge broke with excessive stress and tension on the belt
Embrittlement
Expose to oxidizing, reducing or carburizing atmosphere
Abrasion
Excessive friction from moving heavy parts can result in thin spots that lead to tears
U-shape bending
Improper loading
Unbalanced bending
Differential speed wrong on dual pulleys
Copper attack
Damage by acid, chemicals, or heat
Other phenomena
In-house check for reliability
Material certification
Load calculation
Inspection report / QA check
