PROVISIONAL SPECIFICATION,
An Improved Mode of and Apparatus for Casting Ingots of Steel
or Ingot Metal.
We ADALBERT KURZWERNHART, Managing Director, and ERNST BERTRAND,
Managing Engineer, both of Zuckmantl near Teplitz, Bohemia, do hereby declare the
nature of this invention to be as follows:-
According to our invention ingot moulds for casting ingot iron or steel are arranged
in inclined positions and in groups side by side or one above the other, each mould
having at its upper end a hole having a refractory lining for running in the metal.
In grouping such ingot moulds one above the other, we employ longitudinally
divided moulds, which offer the advantage that they need not be made of tapering
form as is the case with ordinary ingot moulds. The line of division of the mould
may be at top, at bottom, or at an intermediate point; in the accompanying drawings
the division is shewn at bottom. As shewn on the drawing each mould division
consists of a strong plate P with side and end ribs or flanges, forming the sides of the
mould. Any number of these divisions may be arranged in combination, being
secured together by screw bolts or wedges. Before fixing the moulds together, the
openings at their upper ends have fitted into them the blocks M of fire clay or other
refractory material, having holes for the passage of the metal, so that all the moulds
communicate by means of these holes with the casting spout or box G placed on top.
Owing to the inclined position of the ingot moulds all gases liberated from the cast
metal can escape upwards through the holes at M, while any permanent formation of
cavities in the ingots will be prevented by the pressure of the head of metal in the
box G, forcing fresh metal into such cavities.
The casting box may consist either of an ingot mould of metal or refractory
material as at Figs. 1 and 2, or it may be of funnel shape as at Fig. 3. Fig. 4 shews
the combination of two sets of the inclined moulds with one and the same casting box,
the two sets being inclined in opposite directions. In a similar manner three or more
such sets may be grouped together.

An Improved Mode of and Apparatus for Casting Ingots of Steel
or Ingot Metal.
We, ADALBERT KURZWERNHART, Managing Director, and ERNEST BERTRAND,
Managing Engineer, both of Zuckmantl near Teplitz, Bohemia, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
According to our invention ingot moulds for casting ingot iron or steel are arranged
in inclined positions and in groups side by side or one above the other, each mould
having at its upper end a hole having a refractory lining for running in the metal.
In grouping such ingot moulds one above the other, we employ longitudinally
divided moulds, which offer the advantage that they need not be made of tapering
form as is the case with ordinary ingot moulds. The line of division of the mould
may be at top, at bottom, or at an intermediate point; in the accompanying drawings
the division is shewn at bottom.
As shewn on the drawing each mould division consists of a strong plate P with
side and end ribs or flanges, forming the sides of the mould. Any number of these
divisions may be arranged in combination, being secured together by screw bolts or
wedges. Before fixing the moulds together, the openings at their upper ends have
fitted into them the blocks M of fire clay or other refractory material, having holes for
the passage of the metal, so that all the moulds communicate by means of these holes
with the casting spout or box G placed on top.
Owing to the inclined position of the ingot moulds all gases liberated from the cast
metal can escape upwards through the holes at M, while any permanent formation of
cavities in the ingots will be prevented by the pressure of the head of metal in the
box G, forcing fresh metal into such cavities.
The casting box may consist either of an ingot mould of metal or refractory
material as at Figs. 1 and la which shew respectively a longitudinal and transverse
section, or it may be of metal lined with refractory material as at Fig. 2, or it may be
funnel shape as at Fig. 3. Fig. 4 shews the combination of two sets of the inclined
moulds with one and the same casting box, the two sets being inclined in opposite
directions. In a similar manner three or more such sets may be grouped together,
being inclined in three four or more different directions.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed we declare that what we claim is:
In the casting of ingots of steel or ingot metal, the use of inclined ingot moulds P
divided longitudinally and arranged in layers one above the other having runner
holes M and a casting box G common to all substantially as herein described with
reference to the accompanying drawings.
