Improvements in the Manufacture of Articles in Iron and Steel and
Alloys of same direct from the Ore.
I, HERMANN NIEWERTII, of Chaussee Strasse, Berlin, Prussia, Engineer, do hereby
declare the nature of this invention to be as follows:
This invention relates to the production of iron and steel goods, such as bars
rods and castings direct from the ore, and is carried out briefly in the following
manner:―
The iron ore, is prepared in the usual manner (roasted &c.,) and then ground
to powder or to pieces of suitable size. If the ores are not pure they may, before.
further treatment, be purified by any of the known means.
The iron ore is first mixed with water, tar or other suitable material having the
same effect and from this material is moulded the articles to be made from the
iron. For tubes and rectilineal objects the mass may be forced out at nozzles by
suitable presses. Wheels and shaped pieces are produced in moulds, or the potters
wheel or similar means are used to produce the required shape..
The objects so moulded are then placed into muffels or ovens suitable shape and
heated after insertion by a gas flame capable of reducing the iron for instance
carbonic oxide, hydrogen, or the like. The reduction may however be carried out
in any other manner.
The reduction of the articles formed from the iron ore takes place at a relatively
speaking low temperature, which is much below the melting point of iron. The
object itself will, by reason of the heat and chemical action generated in the reduc-
tion, be thoroughly welded and form a firm homogeneous mass. The melting process
may however be further promoted by supplying heat from outside.
Whether the material required be cast iron, steel, or malleable iron, entirely
depends on the amount of coal mixed with the iron and the gas employed for
reduction.
It is easy by my process to produce articles of the most complicated shape in steel.
or cast iron, tubes and vessels of malleable iron or steel, columns, articles for daily
use and parts of machinery if made by my method will be of far better quality and
much cheaper than heretofore.
If the articles are to be made of an alloy of iron with other metals, a suitable
amount of the oxide of such metal is added to the iron ore.

page_text: formed, to be particularly described and ascertained, in and by the following
statement:-
This invention relates to the production of iron and steel goods such as bars,
rods, and castings, direct from the ore. At present in the production of articles
from cast iron, malleable iron, or steel, it is necessary to first obtain the cast iron
from the ore by expensive means, and then to further convert the cast iron
into malleable iron or steel, by further expensive means when the articles required
are produced by still further expensive means. By my invention I do away with
all these operations and produce articles either in cast iron, malleable iron, or
steel, direct from the ore, and in many cases, of a far better quality than is now
usual. The invention is carried out in the following manner
The iron ore is prepared in the usual manner as for smelting, and is then reduced
to powder or finely granulated. If the ores are not pure they may before further
treatment be purified by any of the known means. The prepared iron ore is then
formed into a paste by the admixture of water or tar and coal dust, and from this
paste is moulded in any convenient way the articles to be made from the iron.
For tubes and rectilineal objects, the mass may be forced out of nozzles by pressure.
Wheels and shaped pieces can be either moulded or formed by the potters wheel,
or other means suitable to produce the required shape. The objects so moulded are
then placed in muffel furnaces or ovens, and heated by a gas blast capable of
reducing the iron, for instance, carbonic oxide, hydrogen, or the like. The reduc-
tion may however be carried out by other applications of heat. The reduction of
the iron ore takes place at a relatively speaking, low temperature, below the smelt-
ing point of iron. The object itself will by reason of the heat and chemical
action generated in the reduction be thoroughly welded and form a firm homogeneous
mass. The melting process may however be further promoted by outside heat.
The metal obtained namely, iron, steel, or malleable iron, entirely depends on the
amount of coal mixed with the iron ore and the gas employed for reduction. For
common goods the coal dust may be omitted. It is easy by my process to produce
articles of the most complicated shape in steel or cast iron, and tubes and vessels
of malleable iron or steel, and parts of machinery of far better quality and much
cheaper than heretofore. If the articles are to be made of an alloy of iron and
other metals the ore of the different metals of which the alloy consists is mixed
in such proportions that after the removal of the foreign bodies in the metal, the
desired quantity of the metal to form the alloy is obtained.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim is:
The means of producing metal articles direct from iron ore or mixture of ores here.
