:: ROTARY FURNACES ::
Solar Impianti has developed a range of gas and electric rotary furnaces, specifically designed for pre-heating ceramic moulds for investment casting.
The rotary furnaces combine the production advantages of continuous furnaces with the flexibility and handling of the chamber furnaces.
The general demand for continuously complicated moulds, with ceramic core inclusion and with increasing size makes foundry work increasingly more difficult.
Often, therefore, not only in application sectors such as aerospace and energy, but also in industry and mechanics it is necessary to process these costly moulds in a 2 step firing process:
- The first for the Burnout-Prefire in general in extractable bogie hearth furnaces;
- Followed by a thorough inspection, cleaning and preparation of the clusters;
- Lastly a secondfiring to Preheat in a rotary hearth furnace before casting, often in a vacuum melting furnace.
The main advantages in using preheating rotary hearth furnaces are:
Since the furnaces generally work continuously at around 1200°C on a 24-hour basis, energy efficiency is a particularly important aspect of the operation.
Proper design in terms of insulation, combustion and draft system, can allow substantial cost savings.
Thus the adoption of recovery systems, heat exchangers, or recuperative burners can maximise the result; Solar Impianti can assist you in your choice of solution, even calculating your ROI (Return on Investment) for the project.
