I, ALEXANDER EDWIN TUCKER of Holly Street Smethwick Metallurgist do
hereby declare the nature of this invention to be as follows:-
In carrying out the improvements in the Linings & Bottoms of Steel Converters
detailed in my specification of 14507% and joint specification of 75718 I find that
slag, as ordinarily produced in the Basic process for the manufacture of Steel, either
alone or mixed with various bodies such as Lime or oxide of Iron, and cast into bricks
or blocks may be advantageously used for the linings of Copper Lead and other similar
furnaces as well as Steel or Siemens Furnaces & Steel or Bessemer Converters, such
bricks or blocks may be conveniently cast in iron or sand or other suitable mould and
if required may be annealed they may then be used in the ordinary way.

I, ALEXANDER EDWIN TUCKER of Holly Street, Smethwick, Metallurgist 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:
In carrying out the Improvements in Linings and Bottoms of Steel Converters etc.
detailed in my specifications of 145078 and joint specification of 757185 I find that
Thomas Gilchrist slag as produced preferably in the Basic Bessemer Converter but also
in the Basic Siemens Furnace may be advantageously applied to various Metallurgical
Furnaces as herein described.
For Smelting and Reheating Furnaces employed in the Metallurgy of Copper,
Lead, Iron Steel etc. I prefer to make the roofs and sides of bricks which may either
be cast or compressed from Basic slag. In making cast-bricks the slag is melted in a
suitable furnace or cupola preferably lined with a neutral or basic material and is then
run into either sand or iron or other suitable moulds, the bricks being afterwards
annealed when necessary. For the bottoms or hearths of many Furnaces as in the
case of "Iron Refineries," Reheating or Mill Furnaces etc., I find it more convenient
to make the bottom by spreading over it a layer of coarse slag and then some fine
slag on the top of this and glazing the whole before using. In some cases where it is
not desirable to rebuild the whole furnace of slag bricks, the hearths or bottoms may
be put in in this way without any danger of their fluxing with the ordinary firebrick
walls. By the use of such linings much economy in the ordinary waste of metal i
effected and in the case of Iron or Steel reheating Furnaces a better surface is obtaine
on the sheets, plates or bars etc., and a cinder very rich in oxide of iron is produce
and as free from Silica and Phosphoric acid as the "best puddler's tap" cinder, instea
of the ordinary siliceous "flue cinder" obtained from the usual sand bottom furnace
The cinder I produce forms therefore an excellent fettling for the puddling furnace.
Having now particularly described and ascertained the nature of my said Inventic
and in what manner the same is to be performed, I declare that what I claim is:-
1. The manufacture of Bricks by casting Thomas-Gilchrist slag as herein describe
2. The construction and lining of Metallurgical Furnaces either in whole or in pa
with such bricks.
3. The formation of hearths or bottoms of Iron Refineries, Metallurgical Smelti
and Reheating and other similar furnaces by Thomas-Gilchrist slag as herein describe
Dated this Ninth day of April 1887.
