Heat treating furnaces of
steel industry are manufactured in using the same basic units for the design.
Certain difference can be found only in design of wall construction and in
A separate group is
represented by the bell-type and hood type furnaces. These equipment are
primary used for heat treating of coils, wires and bands. In viewing the
dimensions of charges they are manufactured with various dimensions and
capacities. Matching to the technological aim an optimum number of basements
and heating bells can be produced.
The bell-type furnaces are
furnished with computerised control. In order to meet the requirement of
stringent accuracy of temperature uniformity within the charge, heavy duty
furnace atmosphere blowers are applied. In order to achieve the required
efficiency by gas firing, recuperators are playing an important role as well as
the management of the proper mass flow.
Heat treating furnaces are
manufactured for gas and electrical heating. The rapid and controlled cooling
of the charge can be done by applying cooling bell (bell type furnaces), or by
flowing the atmosphere through water-cooled coolers, resp. in using cooling
During the development
activity was also realised the simultaneous control of furnace batteries both
from the spot and from the central control room too. By using of PC operated
system, the quality certification and archiving technology was elaborated too.
