Vertical vacuum furnace VVF type

Vertical vacuum furnace VVF type

Vertical vacuum furnace has many advantages. High automation limits manual work just to loading and unloading the heating chamber. It guaranties high repeatable results of heat treatment, saving energy and reducing cycle time. The treated elements obtain higher cleanliness than those treated in solt bath or atmospheres with oil quenching. The vertical construction lets to harden long shape detailes without risk of distortion.

Features: round heating chamber, user-friendliness, compact construction, minimal heat loss, overall units treatment, internal cooling system, easy and safely maintenance, automated loading/unloading of batch, wide scope of use, fast and steady batch warming-up, deformation-free long batches´ processing.

Processes: hardening, degassing, soldering, permeating, tempering, highalloyed steel hardening

The series of vertical vacuum furnaces is adjusted to suit the standards of aircraft, automotive and tool industries. Optionally, your furnace may be equipped with a high vacuum system, convection heating and cooling in 0.5,6,10,12,16 and even 20 bar cooling gas overpressure of nitrogen, argon, hydrogen, helium atmospheres or mixtures thereof. An adequately selected set of pumps ensures a vacuum level from 5x10-1 mbar to 5x10-8mbar. Working heat treatment temperature ranges from 120 °C up to 3000 °C.

Graphite heating chamber

In an attempt to meet the requirements of contemporary heat treating technology, here at AMP we have developed graphite insulation of heating chamber based on a monocylinder made of graphite felt and graphite foil. The combination of those two materials resulted in a new insulating composite which surpasses the traditional insulating packs based on polygonal construction. Our solution permits energy saving and guarantees temperature uniformity from +/- 2 °C. The heating element is made of light bent graphite strips while large radiation surface ensures high dynamics of heating and proper temperature distribution.

Molybdenum heating chamber

A molybdenum heating chamber is used where high purity of treatment is required as well as in applications with high and ultra high vacuum. The insulation pack consists of a few layers of thin sheets of increased resistance to temperature and two or three layers of molybdenum sheets. For certain applications the sheets feature and addition of Lanthal. In order to increase their life-span they are lined with a 1 mm thick layer of graphite foil. The heating element is made of molybdenum of increased recrystalization resistance (alloy addition of La). Lengthwise fluting is provided in order to stiffen each heating element.


Process control system.

Our process control system is based on a high class logic controller integrated with an operator's touch panel designed for industrial working conditions. The control systems features a few access levels, which enables an arbitrary configuration of treatments. Visualization of events and alarms permits a hands-free operation. The AMP systems has a provision for remote control and maintenance of the equipment from any computer logged on to the Internet, Ethernet or likewise network.

AMP designs and manufactures their equipment in compliance with the standards specified by the customer. These standards include: PN/EN, NEMA, NFPA, BAC5621, SAE AMS 2750D, SAE AMS 2769, ВАС 5617, GAMPS 5101, P.S. 15000, MMC282 and others. All equipment made to aviation industry standards are ready to handle treatments in accordance with requirements of NADCAP.

Workload fixtures

Every AMP furnace may be equipped with workload fixtures on as required basis. Workload trays or hearth may be made of CFC composite, heat resistant steel or molybdenum. All fixtures are selected to suit individual requirements of the customers and their strength is optimized through the design and calculation system MES.
