PROVISIONAL SPECIFICATION.
Improvements in Converters or Apparatus to be employed in the
Manufacture of Steel and Ingot Iron.
I, JOSEPH EBOR MITCHELL, of 9, Regent Street, Barnsley, in the County of
Lancaster, Mining Engineer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in converters or apparatus to be
employed in the manufacture of steel or ingot iron, the object being by the
improved and novel constructions of converter hereinafter described to obtain
greater heat and better practical results than heretofore. The invention consists
in so constructing and arranging the converter and the tuyers used in combination
therewith that the air blast has a tendency to cause the mass of molten metal in
the converter to rotate in a gradually decreasing circle and the metal is thereby
carried from near the sides of the converter to near the centre and being kept
constantly in motion or gyrating, is brought down much quicker than heretofore.
According to this invention we employ a vessel or converter similar in shape
to any of the ordinary and well known converters, such for instance as a Bessemer
converter, or a cylindrical converter having a conical or tapering bottom.
In connection with the converter or vessel we arrange a series of tuyeres or
pneumatic blast pipes by which a blast of air is directed onto the metal in the
converter. The tuyeres or blast pipes are placed horizontally or thereabouts, and
on one and the same line or plane. The tuyeres are arranged so that a stronger
air blast is directed on one side of the converter than on the other, as for example
by having four tuyeres directed to one side of the converter and three only to the
other side, and the stronger blast causes the molten metal to rotate or gyrate and
at the same time to move towards the centre without unduly churning or
agitating it.

ascertained in and by the following statement:-
This invention relates to improvements in converters or apparatus to be
employed in the manufacture of steel and ingot iron the object being by the
improved and novel constructions of converter hereinafter described to obtain
greater heat and better practical results than heretofore. The invention consists
in so constructing and arranging the converter and the tuyers used in combination
therewith that the air blast has a tendency to cause the mass of molten metal in
the converter to rotate in a gradually decreasing circle and the metal is thereby
carried from near the sides of the converter to near the centre and being kept
constantly in motion or gyrating is brought down much quicker than heretofore.
Such being the nature and object of my said invention the following is a com-
plete description of same, reference being had to the annexed drawings, in
which:-
Fig. 1 is a sectional side elevation of the improved converter.,
Fig. 2 is a sectional plan view on line A, B of Fig. 1.
According to this invention we employ a vessel or converter 1 similar in shape
to any of the ordinary and well known converters, such for instance as a Bessemer
converter or a cylindrical converter having a conical or tapering bottom 2 and an
inclined and contracted upper part 3.
In connection with the converter or vessel 1 I arrange a series of tuyeres or
pneumatic blast pipes 4 4* by which a blast of air is directed onto the metal in
the converter. The tuyers or blast pipes 4 4* are placed horizontally or thereabouts
as shewn, and on one and the same line or plane. The tuyeres 4, 4 are arranged
so that a stronger air blast is directed on one side of the converter 1 than on
the other, as for example by having four tuyeres 4, 4 directed to one side of the
converter and three tuyeres 4*, 4* only directed to the other side, and the stronger
blast causes the molten metal to rotate or gyrate and at the same time to move
towards the centre without unduly churning or agitating it.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
(1) The improved converter herein described and substantially as illustrated by
the annexed drawings.
(2) A converter in which the tuyeres are arranged horizontally or thereabouts
and in such a manner that a stronger blast is directed on one side of the converter
than on the other as and for the purpose herein. described.
