Improvements in Ferro-sodium Fluxes.
I, WALTER JOSEPH MAY, of No. 105, Gibbon Road, Kingston on Thames,
in the County of Surrey, Engineer, do hereby declare the nature of this invention
to be as follows:-
:-
My invention relates to improvements in ferro-sodium fluxes. In carrying it
into effect, I proceed as follows.
Cast iron or steel is melted in a crucible, cupola, blast furnace, or other suitable
melting apparatus, and is poured in a molten state on to beds composed of iron.
borings and chloride, carbonate, or other salts of sodium in an intimately mixed
and mechanically or chemically combined condition, and the molten iron thus
poured on the beds is covered over with a sufficient thickness of a similar mixture
of borings and sodium salts, to prevent or extinguish the flames arising from the
iron. In this way the salts are decomposed and metallic sodium is set free, in
which state it forms an alloy with the iron, while part of the salts in an altered
state also remain adherent to, or combined with, the alloy of metallic iron and
sodium. All or any of the salts of sodium may be used in this process, usually
having an excess of what the molten iron will pick up and convert, but the exact
weights cannot be definitely fixed, owing to the fact that different qualities of iron
require different quantities of sodium salts to produce an alloy with the liberated.
metallic sodium.

improvements in Ferro-sodium Fluxes.
I, WALTER JOSEPH MAY, of No. 105, Gibbon Road, Kingston on Thames,.
in the County of Surrey, Engineer, 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 :-
The present invention relates to improvements connected with ferro-sodium.
fluxes and consists in an improved process for the production of them.
The state of the art in respect of this class of fluxes is to be found in the
Specification of Letters Patent No. 3493 of 1892. This specification describes a
ferro-sodium flux and the distinctive process by which it is produced-such
process being a crucible one as distinguished from an open hearth one.
According to the present invention cast iron or steel is melted in a crucible,.
cupola, blast furnace, or other suitable melting apparatus, and is poured in a.
molten state on to beds composed of iron borings and chloride, carbonate, or other
salts of sodium in an intimately mixed and mechanically or chemically combined
condition, and the molten iron thus poured on the beds is covered over with a
sufficient thickness of a similar mixture of borings and sodium salts, to prevent or

different qualities of iron require different quantities of sodium salts to produce an
alloy with the liberated metallic sodium.
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. The herein before described open hearth process for the production of &
ferro-sodium flux.
2. In process for the production of a ferro-sodium flux, the combination of iron
or steel, borings and any salt of sodium excepting a chloride.
