The furnace is in general a rectangular design and with one main large lifting door providing clear and unosbstructed access to the heating chamber for material charging alloying and drossing etc.
The furnace is hydraulically tilted with two hydraulic cylinders positioned on opposite sides of the furnaces. The Main door is also hydraulically operated. The burners are positioned opposite to both the pouring spout and the exhaust gas duct. The incresases the residence time and optimises path for the hot gases inside the heating chamber. Burners size is according to furnace purpouse melting, holding or alloyingand are controlled aotomatically according to bath and roof temperatures.
Monolithic refractory hearth and wall construction are lined with castables processing non wetting propierties. Flat roof fabricated from steel sections for added stregth and the composite refractory lining is chosen for its thermal propierties and durability.
Dry precast door frame material with the high mechanical strength resistance to temperature fluctuations and abrasion. Charging well and Poring spout axis can be lined with the tilting axis.
This innovate design allows the charging well and pouring spout rotate about tilting axis, and so designed for simultaneous and continuous receiving and pouring of the molten metal on demand.
They count with an open sidewell chamber and molten metal recirculation and stirring system which:. Consist in sink submersion on molten metal while a mechanical metal pump, electrically driven, is stirring. When the impeller and shaft set in the pump housing is roated, a strong vortex of molten metal is generate. When material is feeding into vortex, light aluminium are rapidly submerged in molten metal and melted instantaneously. Quenching Tank water, etc Aging Furnace.
Baskets return systems Optional. Applications Heat treatments of aluminium die-casting process. Additional Options Lineal or “U” type arrangement on site provided with transfer car located between both furnaces.
Automatic basket positioning systems. Automatic load feeding devices. Foundry sand collecting hoppers for being recovered. Direct gas fired heating system by means of burners or electrical heating systems by means of resistances.
In Line Process
Type of Furnaces and Process. Recirculation System They count with an open sidewell chamber and molten metal recirculation and stirring system which: Creates a sink – vortex of hot molten aluminium for melting ligth scraps. Creates a flow of molten metal thorough the open well for melting heavy scraps. Stirrs all the molten metal bath, improving the alloying effect, rsverbero homogenity and temperature uniformity. Ancillary Equipments According to customer request and process needs they can be equipped with: Stationary or Tilting designs.
Dry-hearths for sows or ingot revergero melting. Wide range of holding capacities and combined melting rates.
Low specific energy comsumption. Continous melting in molten metal. Applied sink vortex technology.
Molten metal temperature uniformity. Effective melting require material pretreatment including: Crusher or Rotary shredder, to obtain uniform sizes. Centrifugal Separator, to minimize lubricants and water content. Magnetic or Eddy current separator, to eliminate the ferrous non ferrous or heavy parts.
Reverberatory furnace for primary aluminium
reverbbero Charger, buffer and related belt and screw conveyors, between the different components, with variable adjusted speed. Rotary Dryer or Decoater, for oil coolants or water lubricants evaporation, supplying hot material ready to be melted.
