HORIZONTAL DOOR FURNACES
This range comprises the traditional furnaces loaded horizontally through a door. These furnaces are able to perform all heat treatments, both on small quantities and on medium-large charges, guaranteeing high quality treatment results. They are available in various sizes and can be constructed in different configurations, with graphite or metal chamber and low or high vacuum, depending on their intended use. They are therefore able to deliver an appropriate response to the needs of all heat treatment operators in the most widely varying fields of application.
LARGE HORIZONTAL FURNACES
Chamber
The main characteristic of these furnaces is the use of the vacuum to treat very large, heavy components. As an alternative to mobile hearth solutions, furnaces can be equipped with an automatic tending system capable of loading and unloading even very heavy, bulky pieces in safety.
The studies and tests performed have enabled our design engineers to develop innovative solutions on this type of furnace as well, to improve performance both during heating, for more uniform, faster irradiation, and with regard to gas circulation during cooling.
Accessibility and safety
This series of furnaces is able to treat extremely large workpieces; these large dimensions cause an exponential increase in the difficulties of managing safety and accessibility, as well as in guaranteeing reliability over time. The design work done to develop the right solutions for handling equipment and the structures for accessing parts above the ground has therefore been of fundamental importance. The measures introduced on these furnaces to comply with safety parameters and the relevant regulatory requirements have also been crucial.
VERTICAL FURNACES WITH MOBILE HEARTH
Vertical furnaces with mobile hearth
These furnaces have been developed in response to specific treatment needs, which require the workpieces to be positioned vertically. These applications include a number of uses in the aviation sector, such as landing gear, in industry for the production of dies or extruders, or when the pieces for heat treatments are particularly tall, as in the case of tubes or cylinders; in this case the best solution is without a doubt to choose a vertical furnace, specially designed for the heat treatment of workpieces with shapes of this kind.
Designed for special applications
The capability for loading from below by lifting the mobile hearth and a variety of support options depending on operating needs mean that the right answer is always available for every application. If the parts for treatment are particularly large and heavy, or complex shapes make handling problematical, a VBL furnace is certainly the best solution; the hearth moves vertically for easier loading access and also travels horizontally outside the furnace for easier loading and unloading of the workpiece. With this system, loading and unloading by means of a hoist or bridge crane is a simple procedure.
VERTICAL PIT FURNACES
When the workpeices are not only long but also require special loading arrangements, as in the case of blades or broaches, positioning must be uniform with the stresses distributed along the workpieces; suspension is one option, which minimises deformations and the consequent need for post-treatment machining. The right product should be chosen for these specific needs; VTL series furnaces offer the best guarantees of good results when treating workpieces of this type.
Unbeatable flexibility and solutions
Apart from the choice of loading arrangements, vertical furnaces also offer a large number of alternatives with regard to both chamber type and vacuum level, not to mention convection heating for some treatment requirements. The choice will always depend on the user’s needs and will aim to provide the most convenient operation without sacrificing versatility and quality of results. Here again, these furnaces are very flexible in use, thanks to the options available and the large number of parameters for setting to create heating and cooling cycles that are precise in all phases of the treatment.
