SEH Furnace

Flux Treatment in the Melting Chamber

Freshly melted, semi-molten aluminium is flux-treated and skimmed of dross in the melting chamber. Compared with flux work in a reverberatory-type holding chamber, heat exposure is greatly reduced, easing the burden on operators.

Connecting Port Between the Melting and Holding Chambers

A weir formed by a ceramic plate prevents flux residue from flowing into the holding chamber.

Holding Chamber Inspection Hatch

Maintaining the holding chamber is as simple as raising the hatch and removing the oxide film from the melt surface. The refractory lining is a high-alumina material with low wettability to molten aluminium, installed as a single monolithic casting.

With its small heat source and thick insulation, the holding chamber’s outer wall surface stays at just 20°C above ambient temperature.

Heater Tubes

For general die-casting applications, the Hicera ceramic tubes are guaranteed for two years, with a proven service life of up to four years.

Heat exchange takes place along the tubes’ full depth, keeping the holding chamber compact.

Heater Heat Generation

The furnace is designed so that the heating elements remain immersed in the melt at all times during continuous melting.
Because the chamber atmosphere is warmed only by radiant heat from the melt, it stays at nearly the same temperature as the melt itself — shutting out a major cause of oxide growth.

• Melt temperature accuracyWithin ±2°C
• Heat-up rate35–40°C/h

Melting Burner Combustion Control Unit

The unit is housed beneath the melting chamber, so there is no need to climb onto the furnace for maintenance — inspection and servicing can be carried out safely.
