Continuous Mesh Belt Hardening Furnace (Roller Hearth Type) for Heat Treatment

Roller Hearth Mesh Belt Furnace is a continuous controlled atmosphere heat treatment line, widely used for batch processing of small metal parts in industries such as automotive, bearing, and fastener manufacturing.

The most distinctive feature of the equipment is the roller support for mesh belt operation. A series of cylindrical rollers are arranged inside the furnace chamber, with the mesh belt laid on top and driven by these rollers. Compared to traditional drag-plate structures, this design offers the following advantages:

1.More stable operation – rolling friction of rollers, no jamming

2.Longer mesh belt life – elimination of sliding wear

3.High product consistency – uniform and stable transmission speed

Mainly used for large-scale, small-to-medium sized metal parts requiring minimal or non-oxidation heat treatment. Common parts include:

1.Bearing rings and rolling elements

2.Fasteners (bolts, nuts, washers)

3.Chain components

4.Hardware tools

5.Automotive and bicycle parts

The complete production line typically includes the following core units:

The equipment supports multiple heating options:

1.Pure electric heating (electric radiant tubes): precise temperature control, clean and environmentally friendly

2.Gas/oil heating: lower operating cost

3.Gas-electric/oil-electric combined heating: balances cost and precision
