A vacuum furnace is a type of furnace in which the product in the furnace is surrounded by a vacuum during processing. The absence of air or other gases prevents heat loss from the product through convection, and removes a source of contamination. This enables the furnace to heat materials (typically metals) to very high temperatures, and to carry out processes such as brazing, sintering and heat treatment with high consistency and low contamination.
Here we have some technical and construction characteristics via HTS Vacuum Furnaces, designed using latest-generation software and innovative development techniques:
- The chambers are designed and built to ensure the lowest possible heat loss during heating, meaning the lowest energy consumption and the fastest gas discharge during cooling. Ongoing research is directed toward solutions to reduce the deformations during thermal shocks during the various phases of the production cycle.
- Convection Heating If properly designed, correctly implemented and configured, convection heating helps to increase irradiation performance during low temperature heating procedures by favouring thermal irradiation and improving temperature uniformity conditions.
- Cooling: uniform, efficient cooling gas distribution allows the achievement of excellent results across the entire charge and helps to reduce the temperature more quickly, shortening the cycle duration and optimising energy efficiency.
- The vacuum pumping unit is designed to speed up the initial phase of the treatment cycle by reaching the operating vacuum fast, thus reducing cycle duration.
- The cooling water is distributed by means of a suitable pipe network and state-of-the-art flow control and monitoring systems, which guarantee a longer lifetime and lower maintenance costs.
- The handling systems of HTS furnaces are based on continually evolving solutions, with in-depth analysis of the materials and the working conditions on which they will be applied. They are constructed with the aid of clearly defined techniques and procedures in all assembly phases, for absolutely reliable end results.
- Some treatments require precise control of operating pressures; inert atmospheres can be controlled in manual or automatic mode, in static conditions or with continual flushing.
