To succeed in secondary aluminium processing cost effective melting is essential. This means using the most energy efficient melting and highest level of automation to reduce labour costs and most importantly to gain the highest metal recovery.
Our range of gas and oil fired melting furnace includes:
• Reverberatory melting with extended charging slopes stationary or tilting
• Twin chamber melting furnaces with a variety of metal circulation systems
• Sloping hearth furnaces, with special dry hearths for separation of iron inserts in scrap
• Side well furnaces. Classic designs with external side wells for melting of thin gauge scrap such as swarf, turnings and chips
• Crucible melting furnaces for use in foundries and die casters
• Rotary furnaces for all types of scrap and particularly for dross processing
The selection of the correct furnace to melt specific scrap is the key and Melting Solutions not only build all types of melting furnaces but can offer advice to select the right furnace backed by the long practical experience of our team.
Characteristics of our advanced melting furnaces include:
• Full size doors to enable fast charging and access to the furnace
• Door surrounds protected with heat resistant cast plates to protect refractories and ensure a lasting door seal
• With high melt rates and high power inputs burner systems are selected to reuse waste heat from flue gasses by recuperative and regenerative burners. Oxy fuel alternatives are also available.
• Non contact bottom or side induction stirrers for improved metal circulation and unrivalled melt homogeneity
• External charge wells either side, closed or EMP systems available according to scrap type
• Refractory linings with high thermal insulation and chemical resistance to corundum formation
• Accurate pressure control using high temperature flue dampers operated from sensitive pressure transducers
• Correctly designed furnace geometry to allow easy cleaning of furnace slopes
• Optimised burner positions and door sizes
• Doors supplied with clamping mechanisms and seals to conserve energy
• Models available with ceramic diffusers (porous plugs) embedded in the hearth for injection of nitrogen, argon and gas mixtures containing chloride
• Including extraction hoods and furnace flue arranged on tilt axis ‘knuckle joints’ for ease of duct connections
