描述
This furnace represents an advanced solution for the
heat treatment processes
as it is suited to various materials to be treated and to many different types of charge and piece geometry.
The heating up of the charge may be applied either in
high vacuum
or with
partial pressure of inert gas
. This is made possible by an automatic system that regulates the vacuum within the range of 0,1 to 1 mbar at a preset level, introducing argon or nitrogen.
Quenching
of the charge can be achieved either in middle vacuum or by gas flow.
The pressure can be preset between 0.8 to 1.0 bar and circulated by a
centrifugal fan
.
During the quenching phase it is possible to circulate the gas (nitrogen, argon, etc.) at a maximum pressure of 1.0 bar cooling the charge from above, from below, from top and bottom, alternately, or top and bottom together producing the
fastest decrease of charge temperature
with the
best uniformity
.
