GEORGE E. GAIL, JR., F LONTIAC, MICHIGAN, ASSIGNOE OF ONE-SIXTH TO HARRY A. SIBLEY AND ONE-SIXTH T0 GEGEGE A BROVJN, BOTH OF PONTIAC, MICHIGAN METAL-CHIP BRIQUETTE.
I No Drawing.
To all whom it may concern:
Be it known that I, Gnoncn E. GAIL, Jr., a citizen of the United States of America, residing at Pontiac, in the county of Oakland and State of Michigan, have invented certain new and useful Improvements in Metal-Chip Briquettes, of which the following is a specification.
The invention relates to the manufacture of briquettes of finely divided scrap metal such as cast iron borings, turnings etc. The obiect of the invention is to produce a bri uette adapted to be used in a cupola so that the scrap metal may be re-melted in a foundry instead of being returned to the blast furnace, the latter being the usual practies.
In order to provide a practical briquette for use in a cupola it is necessary to provide a suitable binding material which is capable of withstanding a very high temperature so that the briquette will retain its form until the metallic ingredients assume the molten condition. My improved briquette will fulfill the above requirements and in addition, is capable of being manufactured by a simple and cheap process so that a reat saving is made by briquetting all of the scrap material and reintroducing the same into the cupola.
According to my invention the metallic chips are mixed with a diluted solution of commercial water-glass (silicate of soda) and then placed in suitable molds in which the metal is compressed by tamping or other suitable means. Th briquette is then dried preferably by heating to a temperature of approximately 100 F. for from 15 minutes to an hour and then removed from the mold.
In this condition it is ready for immediate use in the cupola.
As an example of the process which may be used in the practical preparation of the briquettes one ton of iron chips is mixed 4 with a solution comprising one and one-half gallons of commercial water-glass 47 Baum and ten gallons of water. This mixture may be molded to any desired size, but as an example, I prefer to form fifty pound Serial No. 6,459.
briquettes since this has been found to be.
a good practical size for the cupola. What I claim as my invention is:
l. A briquette adapted comprising a dried comp tallic chips and a binder incorporated therefor use in cupolas acted block of mein consisting solely of diluted liquid Water glass, said briquette bein capable of Withstanding high ten'iperatures without premature disintegration.
2. A briquette adapted for use in cupolas comprising a dried compacted mixture of finely divided cast iron scrap metal and a binder consisting solely water-glass said mixture tially the following proportions, iron, one
of diluted liquid being in substanchips with a binder. consisting solely of liquid water-glass, compressing the mixture in a mold, and drying the same.
4:. The process of manufacturing briquettes comprising the mixing of as borings, turnings and the like with a binder consisting solely glass the mixture being metallic chips such 76 of diluted waterin the proportions of substantially one and one-half gallons of commercial water glass and ten gallons of water to one ton of metal, compressing the mixture in a mold and heating to a temperature of substantially 100 or over.
5. A briquette adapted comprising a dried comp F. for 15 minutes for use in cupolas acted block of metallic chips and a binder incorporated therein containing liquid water glass as the principal ingredient, said briquette being capable of withstanding high temperatures without premature disinte ration.
6. A briquette adapted for use in cupolas comprising a dried compacted mixture of finely divided cast iron scrap Ilibbutl and a binder of dlluted water glass, said briquette being capable of withstanding high temperatures without premature disintegration,
the binding action bein to the water glass.
,9, due principally 7. A briquette adapted for use in Cupolas comprisinga dried compacted mixture of finely divided cast iron scrap metal and a binder containing diluted liquid Water glass, said mixture being in substantially the following proportions, iroin one ton, commercial water glass one and one-half gallons, Water ten gall011s,'tlie binding action in said mixture being due principally to the Water glass.
8. A briquette adapted for use in Cupolas comprising a dried con'ipacl'ed block of inetallic chips and a binder incorporated therein containing liquid water glass, said briquette being capable of withstanding high temperatures Without premature disintcgiiation, the binding action being due, prim cipally to the Water glass.
In testimony whereof I fli'fiX my signature.
