Die Casting: Briquette Drying

By Furnace Engineering

Furnace Engineering manufactures Burn Off Furnace for the Drying of Aluminium Briquettes prior to remelting. The briquetting of aluminium swarf or chips results in moisture retention of 2-3%.

The drying process removes the risk of charging moisture into your melt which results in the emission of hazardous smoke or fume.

Key benefits:

  • The drying process is completely automatic and the process is labour efficient
  • Furnace is completely constructed and tested at the factory to reduce site installation time and costs
  • Furnace is equipped with water-spray system for smoke emission and over-heat control.
  • Efficient incineration of smoke. fumes & gases during drying
  • Pollution free - heat process removal of thermal degradable fluid from the briquettes
  • Recorder (printed charts) provides log of work completed
  • Unique control system with touch-screen interface for control setting and diagnostic
 

The Environmental Cleaning Method

 

BODY

The furnace interior is constructed with heavy gauge sheet metal, reinforced with beams for rigidity and strength. Joints are welded and seams sealed maximum heat efficiency and reduced energy cost.

FLOOR

The floor is constructed with hard cast refractory, 75mm thick and reinforced with structural steel channels for easy removal of any residual ashes.

DOORS

Doors are equipped with cam type lock assemblies and tadpole sealing gaskets. Access to the furnace is via swing aside door(s) located at one end of the work chamber and provide full access to the oven interior.

EXPLOSION RELIEF

Our furnace is equipped with a unique gravity sealed top relief which automatically opens to relieve excessive pressure. The conventional spring latched front doors or blow out panels traditionally used for explosion relief is not ideal because the materials inside will burn out of control once the relief is opened,

INSULATION

Walls, ceilings and doors are sandwiched with 75mm light-weight ceramic fibre blanket insulation anchored with stainless steel pins, stainless wire mesh, and stainless locking washers. It is asbestos free and has superior properties to either asbestos or fibreglass. The end result is a much lighter furnace with higher energy efficiency rating.

VENT STACK

The vent is made into 900mm long lightweight sections for easy installation. It is constructed with stainless steel exterior and lined with high temperature ceramic fibre inside. Sections join by snapping together.

MODELS

Furnace manufactures three different models to best handle your cleaning and stripping jobs from 2% - 50% combustible content.

FUEL

Our furnace operates on Natural Gas, Propane Gas or Fuel Oil.

ELECTRICAL SERVICE

240 volts, 50Hz, single phase, 5 Amp draw.
Optional - transformers available for other voltages.

WATER SUPPLY

Minimum pressure 40 PSI: maximum 100 PSI for water injection system.
Maximum flow rate is 1.2 litres per minute.

NORMAL CYCLE TIME

30 minutes to 4 hours plus cooling time.
Longer cycle may be required for extra heavy loads.

CYCLE TEMPERATURE

Typically set between 300°C & 480°C.

POLLUTION STANDARDS

Complies with strict environmental regulations

SAFETY AND HEALTH STANDARDS

Complies with OHSA regulations.
