Product category: Ingot casting, Continuous casting

Single Chamber Melting & Casting Furnace

Single chamber furnaces generally require comparatively low investment costs. Furnace design is simple, rectangular or round, depending on individual application.

The rectangular furnace design with its front door across the full furnace width allows for maximum access during charging and skimming. Such design is well suitable for melting of clean scrap, ingots, sows etc (type I) with a melt rate of 2 - 15 tons/hour. With regenerative burners energy consumption below 600 kWh/ton is easily achieved.

Single chamber melting furnaces are designed either for hydraulic tilting (as casting furnace) or stationary, as required.

Product category: Smelting

Multi Chamber Melting Furnace (Ecomelt)



Hertwich Ecomelt Melting Furnaces are generally based on integrated scrap preheating / delaquering and submerged melting process. They are designed for remelting of scrap with impurities like oil, paint, and plastic. Total non-metallic organic substances may reach 10% of charge weight, subject to calorific value.

Savings come not only from avoiding shredding and separating, but significantly from thermal reclamation of the hydrocarbons from paint and plastic. During preheating of such scrap, up to 80% of the gas consumption is substituted by the inherent energy of the gasified hydrocarbons.

The specific fuel gas consumption varies from 350 to 550 kWh/ton of aluminium during continuous operation subject to the quantity of organic impurities.

Universal Rotary Tilting Furnace (URTF)


The Universal Rotary Tilting Furnace is particularly suitable for melting of dross and low grade scrap with organic impurities > 10% or high iron content. The name is derived from the fact that this is the most versatile Rotary Tilting Furnace on the market. It represents leading edge technology to sustainably contribute to environmentally sound yet economic scrap recycling and is designed for three process options:

  • Low salt process
  • Salt free ALUREC® process
  • Calcium aluminate process
The Hertwich URTF is available in five standard sizes, 3, 5, 10, 14 and 20 whereby the number indicates the useful furnace volume in m³. Correspondingly the melt rate ranges from 1,5 to 9,0 tons/hour.
