Main Heat Treatment Processes Applying Flat Wire Mesh Belt

Annealing & Stress RelievingFor stamped metal parts, copper alloy accessories and precision castings, flat wire mesh belts carry workpieces through multi-temperature zone annealing furnaces. The high open-mesh structure enables full circulation of protective atmosphere (nitrogen, hydrogen), eliminating surface oxidation and uneven heating. Low thermal mass of flat wire shortens furnace temperature recovery time and cuts energy consumption by 10%–18% compared with solid plate conveyors.

Quenching & TemperingIn continuous quenching-tempering integrated furnaces, 310S or 314 stainless steel flat wire mesh belts withstand sustained temperatures up to 1050°C. After high-temperature austenitizing, belts transport parts directly into oil or water quenching tanks. The flat wire structure resists thermal shock and liquid corrosion without permanent bending deformation, supporting 24-hour uninterrupted production of bolts, nuts, gears and cutting tools. Post-quench tempering sections also rely on flat wire belts for slow, uniform reheating to release internal stress.

Brazing & SinteringCopper brazing of heat exchangers, powder metallurgy sintering and stainless steel vacuum brazing all depend on flat wire mesh belts. The smooth flat surface avoids scratching polished workpiece surfaces, while uniform air/gas flow ensures consistent brazing filler melting and tight sintering density. Many radiator and electronic hardware manufacturers choose customized narrow-pitch flat wire belts for tiny component conveying.

Carburizing & CarbonitridingControlled-atmosphere carburizing furnaces use heat-resistant alloy flat wire mesh belts. Even mesh gaps guarantee equal carbon potential distribution on every workpiece, effectively reducing product hardness deviation and improving finished product pass rate in large-scale fastener production lines.
