PROVISIONAL SPECIFICATION.
Certain Improvements in the Manufacture of Iron and Steel and
other Metals, and in Apparatus to be Employed in the said
Manufacture.
I, HENRY GETHING RICHARDSON, of Hawthorn Cottage, Wordsley, in the
County of Stafford, Glass Manufacturer, do hereby declare the nature of this
invention to be as follows:-
This invention cousists of the hereindescribed improvements in the manufacture
of iron and steel and other metals and in apparatus to be employed in the said
manufacture. By my said invention I purify and improve the quality of the iron
or steel or other metals at the point or place of conversion or reduction of the ore
to the metallic state in the blast furnace or whilst the iron or other metal is being
heated in the refinery furnace. When my said invention is applied to a blast
furnace for reducing iron ore I either make the iron produced better in quality and
more suitable for puddling or I make the iron more suitable for the production of
steel, this depending upon the kind of purifying materials which I use and mix
with the molten metal, as hereinafter described, at the point or place of conversion
or reduction of the ore to the metallic state.
I will describe my invention as applied to melting iron ore in a blast furnace.
According to this invention I inject, force, supply and deliver through tuyere
pipes, or tubes, flues, or passages, into the blast furnace, at the point or place of
conversion or reduction of the ore to the metallic state, such chemicals gases or other
materials as are suitable for purifying the iron the said chemicals or other materials
being injected forced supplied or delivered through the said tuyere pipes flues or
passages by the aid of a blast of steam or hot or cold air or gas.
I may thus deliver carbonates, oxides, nitrites, muriates, or other suitable
substances for the purifying of the molten metal at the point of conversion in
particles and in suitable quantity to have the desired effect upon the molten metal.
Thus by my invention anyone may with proper materials desulphurate or
dephosphorate or otherwise purify the iron at the time of melting or fusing of
the ore.
I may pass the said purifying materials or gases into the blast pipe or blast pipes
from a tank or hopper or other chamber or through the blower by which the blast
is produced, in the same way for instance as sand is delivered from a sand blasting
machine to the point of operation. Thus manganese, charcoal, lime or other
suitable purifying materials in a powdered state can be carried by the air or stean
blast or by the gas through the blast pipe or pipes and through the tuyere or
tuyeres into the blast furnace to the point of fusing or melting of the ore; or
the said purifying gas or material can be delivered to the point or place of
conversion or reduction of the ore through another pipe or pipes independent of the
required tuyere or tuyeres now in use.
My method as above described as applied to purifying iron in a blast furnace
can be similarly applied to a refinery furnace the purifying material being carried
into the refinery furnace in a similar manner to that above described with reference
to a blast furnace and delivered at the point or place where the metal is melted by
the blast.

furnace or in a refinery furnace can be similarly employed for the purifying of
any other metals as they are reduced from the ore or fused in a metallic state.

Certain Improvements in the Manufacture of Iron and Steel and
other Metals, and in Apparatus to be Employed in the said
Manufacture.
1, HENRY GETHING RICHARDSON, of Hawthorn Cottage, Wordsley, in the
County of Stafford, Glass Manufacturer, 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 consists of the hereindescribed improvements in the manufacture
of iron and steel and other metals and in apparatus to be employed in the said
manufacture. By my said invention I purify and improve the quality of the iron
or steel or other metals at the point or place of conversion or reduction of the ore
to the metallic state in the blast furnace or whilst the iron or other metal is being
heated in the refinery furnace. When my said invention is applied to a blast
furnace for reducing iron ore 1 either make the iron produced better in quality
and more suitable for puddling or I make the iron more suitable for the
production of steel, this depending upon the kind of purifying materials which
I use and mix with the molten metal, as hereinafter described, at the point or
place of conversion or reduction of the ore to the metallic state.
I will describe my invention as applied to melting iron ore in a blast furnace.
According to this invention 1 inject, force, supply and deliver through tuyere
pipes, or tubes, flues, or passages, into the blast furnace, at the point or place of
conversion or reduction of the ore to the metallic state, such chemicals, gases, or
other materials as are suitable for purifying the iron the said chemicals or other
materials being injected, forced, supplied, or delivered through the said tuyere
pipes flues or passages by the aid of a blast of steam or hot or cold air or gas.
I may thus deliver carbonates, oxides, nitrites, muriates, or other suitable
substances for the purifying of the molten metal at the point of conversion in
particles and in suitable quantity to have the desired effect upon the molten metal.
Thus by my invention anyone may with proper materials desulphurate r
dephosphorate or otherwise purify the iron at the time of melting or fusing of
the ore.
For instance if the iron which is being smelted from the ore in the blast furnace
requires more oxygen at the time of reduction of the ore I may use oxide of
manganese as the purifying material pulverised fine in the proportion of say about
9 lbs. more or less to the ton of iron produced, the manganese to be passed into the
blast pipe at the time the reduction of the ore is completed. If the iron requires
more carbon at the time of the reduction of the ore I may use charcoal dust at the
rate of 6 lbs. more or less to the ton of iron produced or I may use coke dust for
the same purpose in the proportion of say 9 lbs. more or less to the ton of iron
produced. For desulphurising the iron I may use carbonate of lime in the
proportion of 10 lbs. more or less to the ton of iron produced; or I may use
carbonate of lime and muriate of soda combined and well mixed in the proportions
of 5 lbs. of carbonate of lime and 5 lbs. of muriate of soda more or less to the ton
of iron produced the mixture to be passed into the blast pipe in a regular flow at
the time of the reduction of the ore.

page_text: I may pass the said purifying materials or gases into the blast pipe or blast pipes
from a tank or hopper or other chamber or through the blower by which the blast
is produced, in the same way for instance as sand is delivered from a sand blasting
machine to the point of operation. Thus manganese, charcoal, lime or other
suitable purifying materials in a powdered state can be carried by the air or steam
blast or by the gas through the blast pipe or pipes and through the tuyere or
tuyeres into the blast furnace to the point of fusing or melting of the ore; or the
said purifying gas or material can be delivered to the point or place of conversion
or reduction of the ore through another pipe or pipes independent of the required
tuyere or tuyeres now in use.
Means for carrying out my said invention are illustrated on the accompanying
drawing on which Fig. 1 shews in part sectional elevation a blast pipe and tuyere
and a tank or hopper and connections for supplying the purifying materials to the
blast pipe. A is the tuyere and B is the blast pipe by which the blast is supplied
thereto. C is the hopper or chamber containing the purifying materials the lower
part of this hopper or chamber having a connecting pipe D through which the
purifying materials can fall into the blast pipe B to be delivered with the blast
through the tuyere A to the point place or spot where the ore iron or other metal
is first melted in the furnace. E is a slide for regulating the flow of the purifying
materials into the blast pipe B.
When supplying purifying gases to the blast pipe B the connecting pipe D
has to be connected by a pipe D1 (see Fig. 2) to a gas holder so as to supply the
gas to the blast pipe B to mix with the blast and be delivered at the place or spot
where the ore or metal is melted in the furnace. F is a valve for regulating the
flow of the gas to the pipe D D¹.
My method as above described as applied to purifying iron in a blast furnace
can be similarly applied to a refinery furnace the purifying material being carried
into the refinery furnace in a similar manner to that above described with reference
to a blast furnace and delivered at the point or place where the metal is melted by
the blast.
My invention as above described with reference to purifying iron in a blast
furnace or in a refinery furnace can be similarly employed for the purifying of
any other metals as they are reduced from the ore or fused in a metallic state.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
:-
1. Purifying or improving the quality of metals by melting the same or their
ores by means of a blast charged with purifying materials or with a purifying gas
or gases which purifying materials or gases are by the said blast delivered at the
point or place where the melting of the metal or ore first takes place in the furnace
substantially as hereinbefore set forth.
2. The combination with the blast pipe and tuyere of a furnace for melting
metals or their ores of a chamber containing purifying materials or purifying gases
and a pipe or passage connecting said chamber to the blast pipe so arranged as to
lead the purifying materials or gases into the blast pipe to be delivered by the
blast at the point or place where the melting of the metal or ore first takes place
in the furnace substantially as hereinbefore set forth.
