Bell furnace is designed for light heat - treatment of
coils of gold - rolled steel tape, also for heat - treatment of middle
and thick hot - rolled plates, bars and wire bundles. The bell type
furnace uses direct radiant heat to deliver a uniform heat to the
workload. Large motors and heaters are heated using these furnaces. They
are also used for annealing large glass masses and for other heat
treating applications in various industries.
Features
- Normally uses firebrick chamber liner backed by slab type
secondary insulation.
- The heating elements are guarded by strong metal alloys.
- Standard parts with little or no maintenance required.
- Carbon steel outer casing painted with a heat resistant paint.
- Heat chamber is controlled automatically.
- The distribution of heat is uniform.
- Over temperature protection.
