MRC MSF 11-3 - Operating the Electric Furnace

10
Prepare the place where the Furnace will be used.
8. PREPARATION FOR USE
The Furnace should be dried before using it for the first time or if it has been out of operation
for a long period of time and stored in humid conditions. It should be dried as follows:
- without load, heat the Furnace until it reaches a temperature ranging from 100-150C
and maintain this temperature range for 2-3 hours;
- heat up to the nominal temperature. Maintain for 1-2 hours.
The dried Furnace can now be operated.
While drying, some ‘smoke’ may appear but it has no effect on further operation of the electric
Furnace.
9. OPERATION
Open the door of the electric Furnace.
Put the load on the bottom plate (-s) at least 1/10 of the space away from the side walls to
ensure a better circulation of air.
When putting or taking off the charge do not damage thermocouple, mounted in the chamber.
The data indicated in technical specifications refer to the working space.
-The supporting surface, where the Furnace will be placed on, must be
smooth and non-combustible.
-To prevent damage to the floor covering or the risk of fire if a hot object falls
during removal from the chamber, the floor covering in the working area of
the Furnace must be non-combustible.
-The Furnace must be installed at a safe distance from the surrounding
surfaces:
-The minimum distance from the rear and side surfaces of the
Furnace to flammable surrounding surfaces is L = 0.5 m;
-The minimum distance from the top surface of the Furnace to
flammable surrounding surfaces is L1 = 1 m;
-The minimum distance from the rear and side surfaces of the
Furnace to non-combustible surrounding surfaces can be reduced to
L = 0.2 m;
-The minimum distance from the rear surface of the Furnace with a
ventilation hole or chimney in the rear wall to the surrounding
surfaces L = 1 m;
In individual cases, safety distances must be adapted to the environment and
larger distances must be selected.
The room where the Furnace is installed must have a good ventilation
system. Working with the processes that emit vapors, fumes, etc. in addition,
we recommend installing hoods or connecting the furnace chimneys to the
ventilation system as shown in the figure.
