A. Defects Noted in Furnace I Which Have Resulted in Structural Ch_ nQes In
1. The upper portion of the steel supports of the skip hoist interfered
with the gam outlet pipes. The Blae2:h~._'t firm, in Leipzig, was to blame for
this error in design.
2. The space between the cold-air sliding valves and the Coy-per atovee vat'
too narrow to allow the counterbalance arm to traverse its prescribed path. The
pipe connections were lengthened from 250 millimeters to 300 millimeters.
3. The cant-iron cmntnrbaiances for closing the shutters on the coke rind
are bunkers were found to be too light. The supplier, SAG (Soviet Corporation)
Mackeosen Melchine-Building Plant, Magdeburg, vill make the necessary adjustment.
4. it was found that the pnermati,:: cylinder used. to r&ct! the small fur-
nace-top bell would not work at a pressure of lace than 8.7 atmospheres. Born-
-... the .. r.are not wbt a to produce sn_ :IS nh a mcesure. The PAtIflLRr-
balance weight vwl reduced from 4.8 tons to 3.4 tone, a:d now the cylinder verka
satisfactorily.

5. The dry valve on furnace I turned out to be of rather poor design. A
valve of improved design has been installed on furnace II, and another is ready
to replace the one now in use on furnace I.
6. When the fuel-gas sliding valves were connected to the Cowper stoves
7. The covers on the blowers buckled. The suppliers, EIO (Federation of
People-Owned Enterprises for Power Plant Machinery and Motors) Bitterfeld, will..

r,acneu,to hue not metal ladles. The tipping stsnds necessary for this operation
will be made by the Mcsenthin firm in Leipzig. In addition, a hoist will be at
tached to the trolley runway to make possible quick replacement of the pouring
spout?.
B. Structural Shortcomings Noted But Not Yet Altered
1. A trolley runway for the replacement of Cowper st..we fittings is absc-
lutely necessary. The ZKB has voraed out designs for approval by the EKC, but
so far the EKO has done nothing in this matter,
2. To prevent endangering the trusses of the pneumatic cylinder if the fur-
nace ohould blow out, the foundations for the trusses should be on the same level
as the furnace foundations, not lower, as they are now. This suggested type of
construction will be carrie3 out on furnace III.
C. Structural Faults Observed in Furnaces I and II for Which Remedial Measures
Will B:z Taken in Furnaces III and IV
1. From furnace III on, the supports of the hot-air pipes will be relocated
to facilitate the installation of the Cowper stove fittings.
2. Because of the position of the probe bar, the balancing supports had tc
be relocated. As a consequence of relocating the supports, the fastening of the
discharge hopper must also be altered. SAG Polysius in Dessau, has been informed
of this.
3. The EKO desired a relocation of the gas line running from the wet valves
to the blowers. The c'haarne could not be carried out on furnace II, but has been
mF+de on furnace III and will be wade on subsequent furnaces. The new location
of the line necessitated attachi.g a bracket to the blower supports.

The diameter of the inner platform is to be increased by 200 millimeters.
The tapping platform is 4o be relocated. The slag platform will have stronger
supports. To protect the carbon lining (Kohlenatoffstempfmasse) of the furnace

walls, the openings through.whirh the blest pipes extend into the furnace will
be surrounded with a layer of firebrick. There has been some change of plan
regarding the projected relocation of the furnace cooling pipes, occasioned in
part by the installation of additional measuring instruments and in part by
structural considerations. The zic has not yet obtained any written statement
on these changes from the EKO.

Iron-tapping platform - The crane runway will be raised one meter. The
minimum distance between the upper edge of the trolley carriage and the lower
edge of the frame is to be ?300 millimeters; The electric cable line will be
fastened to the lower edge of the frame. The platform will support the same
weight as the platforms at furnaces I and II, and in addition there will be a
layer of sand over the whole platform one half meter deep. Catwalks will be
erected on both sides of the platform. The crane track will be strengthened.
Sliding doors are to be installed on the side of the platform which is open to
the weather. The entire platform is to be rcrfed. The ruof covering is to be
of precast concrete slabs with sheet metal louvers. The platform floor is to
be of steel concrete (without sheet metal). An additional pair of supports is
to be installed in front of the control room, as a substitute for the booms.
Slag-tapping platform -- The supports will be strengthened by cross-braci.,g.
The'p.atform floor is to be of steel concrete (without sheet metal). The hand
rails will be raised.
Furnace-top bell -?? It is intended to alter the base and the supports of
the pneumatic cylinder used to raise the bell.
DECREE SETTING UP A COMMISSION TO STUDY THE EKO
L decree was issued by the GDR Council of Ministers on 14 February
1952 setting up a commission to study tr^ situation at the EKO and make
recommendations. The decree statee:/
To accelerate the elimination of all shortcomings and weaknesses in the set-
ting up of the EKO, Fuerstenberg/Oder, there is hereby established a commission
of four experts; who, 'For, a period of 3 months, shall assume supreme coordinating
authority in all activities at the plant, including production, technical in-
stallations, and the erection of buildings. Fritz, Selbmann, Minister of Metal-
lurgy and Mining, shall be chairman of this commission; the members of the com-
mission shall be Graduate Engineer Zieger, Fritz Walter, and Rudolph Rossmeisel.
The commission is responsible for improving the technical and industrial
equipment and the work organization.
