Billet homogenization furnace
The billet homogenization furnace is a chamber type furnace with loading and unloading of the material from the access door to the furnace by means of a semi-automatic loader. The loader deposits the charge in the furnace on special stalls and then it is extracted to allow the kiln to be closed and the cycle to start.
The maximum operating temperature is 650 °C which can be reached through heating ramps created by means of customizable gradients suitable for the type of treatment to be carried out, in compliance with the required performances.
The heating usually takes place by means of free flame cold air burners housed in a chamber separated from the material, located above.
The insulating lining provided is specifically designed to ensure optimal performances of the furnace and is made of fibrous materials suitable for the operating temperature and the required process characteristics. The internal surface of the lining is protected by stainless steel sheets to avoid the lining itself from wearing off due to the high recirculation speed of the internal atmosphere.
The furnace is composed of a monolithic carbon steel carpentry structure.
Peculiarity of billet homogenization furnace
A peculiarity of these systems is the presence of a room housing the burner.
The heating is in fact indirect, i.e. the flame of the burners never comes in contact with the material being treated.
The hot fluids are channeled into special inter-spaces and recirculated in the chamber by means of suitable axial fans.
The use of axial fans allows the inversion of the recirculation flow to optimize the uniformity in the chamber.
Automation guarantees control of the entire process, interfacing with the company supervisor.
This type of system is designed and built to comply with the regulatory standards and the class of belonging of the furnace that the Customer requires (AMS – NADCAP).
