NiTED STATES PATENT CFFICE.
OSCAR MURISIER, OF ALEXANDROWSKY, NEAR ST. PETERSBURG, RUSSIA, AND PERCY CARLYLE GILCHRIST, OF PALACE CHAMBERS, WESTMINSTER, ENGLAND; SAID MURISIER ASSIGNOR TO SAID GILCHRIS'I.
JUNCTION 0R SEPARATOR LINING FOR OPEN-HEARTH FURNACES.
SPECIFICATION forming part of Letters Patent No. 329,937, dated November 10, 1885.
Application filed May 4, 1885. Serial No. 164,373. (No specimens.)
To all whom it may concern:
Be it known that we, OSCAR MURIsrER and PERCY CARLYLE GILCHRIST, respectively a citizen of the Swiss Republic, residing at Alex- 5 androwsky, near St. Petersburg, Russia, and
a subject of the Queen of Great Britain, residing at Palace Chambers,Westminster, England, have invented a certain new and useful Improvement in Junction or Separator Lin- I0 ings for Open-Hearth Furnaces, of which the following is a specification.
In the manufacture of steel in the Siemens or open-hearth furnace by what is known as the basic or Thomas Gilchrist process, much difficulty has been experienced when the silica roof and sides have been allowed to rest directly upon the basic hearth, as in such case the silica combines with the basic material and rapidly melts away, bringing down 20 with it the sides and ports of the furnace.
The object of our invention is to remedy this defect; and to this end we employ chrome ore made plastic with tar as a separator or junction between the basic and silicious mate- 2 5 rials, such junction being preferably above the slag-level. Such mixture, we find, does notflux with either the basic or silica materials, and may be readily put in place by ramming in the ordinary manner, or may be used in the 0 form of bricks prepared by mixing the chrome ore with just sufficient tar to make the mass plastic, such mass being then molded under pressure into the form of bricks, which may or may not receive a preliminary firing before 3 5 being placed in position. The chrome ore and tar junction (whether rammed in situ or used in the form of bricks) need only be of a few inches in thickness, and will rest directly upon the basic material, while the silica will rest directly upon it.
We are aware that it has been before proposed to use chrome ore and oxide of chromium for lining furnaces, as in United States Letters Patent No. 308,984, such lining being highly resistant and interposed between the bath of metal and the ganister or other lining, and. covering the whole of such lining; but such materials have not, so far as we know, been mixed with tar and used simply as a junction or separator, and
What we therefore claim, and desire to secure by Letters Patent, is
1. A mixture of chrome ore and tar, compounded substantially as set forth, for use in separating or forming the junction between the basic and acid portions of the linings of metallurgical furnaces.
2. A furnace-lining composed of a basic bottom, basic sides, and acid roof, and a belt of a mixture of chrome ore and tar interposed between the roof and sides, as set forth.
In witness whereof we have hereunto set our hands,each in the presence of two subscribing witnesses.
