CARL JOHAN SANDAHL, Engineer Trimsaron near Llanelly, GEORGE BARGATE,
Merchant Barrow-in-Furness CHARLES BERRY PHILLIPS, Hoole Cottage Chester,
Gentleman, do hereby declare the nature of this invention to be as follows:-
Instead of manufacturing these several Alloys of Iron direct from their Ores, or a
mixture of several of their Ores, whereby a great loss is caused by the large quantity
of slag produced carrying off with it a large proportion of the Manganese, when either
Ferro-Manganese, Silico-Spiegel Spiegelisen are manufactured or Chromium when
Chrome-Iron is manufactured, these two metals being valuable, and any saving of
them in the manufacture will enable these several. Alloys named to be manufactured at
a less cost than by the process now in vogue.
For manufacturing Ferro-Manganese Silico-Spiegel,eand Spiegeleisen, instead of
using Iron Ores, or Ores, of Manganese or Manganefirous Iron Ores or both, and
smelting them direct from these Ores in the Blast-furnace; we use pig-Iron either
Hematite or other qualities, and charge these pigs broken in pieces with the Ores of
Mangonese or Manganefirous Iron' Ores or both, with the materials required for fluxes,
and the necessary quantity of fuel, into a Blast-furnace of the usual construction
either using the hot or cold blast; the object of this being that the pig-iron being
comparitivly free from impurities, a very small quantity of Huxing Material if any
will be required to reesmelt this Iron, and only sufficient material will be required to
flux the Manganese or Manganefirous Ores from their impurities, the result being that
having such a small quantity of Slag to deal with a very small proportion of the
Manganese or iron will be absorbed by it, and consequently lost, and the saving of
these Metals will more than compensate for the extra cost of using pig-iron instead
of the 'Iron Ores and Manganefirous iron Ores as before mentioned.
For the manufacture of Chrome-iron in the same way as before mentioned we use
pig-iron and an ore of Chromium prefering an oxide of Chromium and Iron, and
smelting these together as for Ferro-Mangonese &c. the saving of Chromium being
the same viz.-less loss in the Slag.

Chrome-iron.
We, CARL JOHAN SANDAHL, Engineer, of Trimsaran, South Wales, GEORGE
BARGATE, Merchant, of Barrow-in-Furness, and CHARLES BERRY PHILLIPS, Gentleman,
of Hoole Cottage, Chester, 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 :-
This Invention relates to the manufacture of Ferro-Manganese Silico-Spiegel
Spiegeleisen and Chrome Iron and has for its object to effect economy in the
manufacture of these alloys by saving manganese or Chromium in the smelting.
In the ordinary method of manufacturing these several alloys of Iron direct from
their Ores or a mixture of several of their ores a great loss is caused by the large
quantity of slag produced, carrying off with it a large proportion of the manganese
when either Ferro-Manganese Silico-Spiegel or Spiegeleisen is manufactured, or
Chromium when Chrome Iron is manufactured. As Manganese and Chromium are
valuable, any saving of them in the manufacture will correspondingly reduce the cost
of the manufacture of the alloys.
According to this Invention in manufacturing Ferro manganese Silico Spiegel and
Spiegeleisen instead of using Iron ores with the Ores of Manganese or manganiferous
Iron Ores (or any mixture of these) and smelting them direct from these Ores in the
Blast furnace we use pig iron or cast iron either Hematite or any other qualities or
pieces with the ores of manganese or manganiferous Iron Ores or a mixture of these
makes of iron or iron or steel scrap. We charge the pig or cast iron or scrap broken into
Ores and the materials required for fluxes and also the necessary quantity of fuel into
a Blast furnace of the usual or any suitable construction either using the hot or cold
blast. As the pig or cast iron or scrap is comparatively free from impurities
a very
small quantity of fluxing material, if any, will be required to resmelt the iron beyond
that necessary to flux the manganese or manganiferous ores from their impurities the
result being that having but a small quantity of slag to deal with as compared with
that to be dealt with in the ordinary method of smelting a very small proportion of the
manganese and iron will be absorbed by it and consequently lost, and the saving of
these metals will more than compensate for the extra cost of using pig iron or iron or
steel scrap instead of the iron ores or manganiferous iron ores or both as before
mentioned.
In like manner in the manufacture of Chrome iron we use pig or cast iron or scrap
and an ore of Chromium (by preference an oxide of Chromium and iron). We smelt
these together with fluxes and fuel as hereinbefore described with reference to the
other alloys, and a saving of Chromium results because there is less loss of Chromium in
the slag just as there is less loss of Manganese in the case of the alloys of manganese
and iron.

page_text: We do not consider it necessary to give any particular proportions as iron and steel
makers will readily understand that any proportions may be used in accordance with
the kind of iron used and the class of product required.
By the use of this Invention the burden in the furnace is richer and consequently
there will be a larger yield for a given charge and corresponding economy in time
labour and expense results. The furnace will also work more regularly and open and
the quality of the material produced will be greatly improved.
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 manufacture of Ferro Manganese, Silico Spiegel, Spiegeleisen, and Chrome
Iron, the use in the smelting process of pig iron or cast iron or iron or steel scrap
substantially as and for the purpose hereinbefore described.
