PATENT OFFICE.
UNITE-D srAirss 80 Drawing. Application filed November To all whom it may concern.
Be it known that Rmmam J. PUGH, citizen of the United States of America, residing at Youngstown, inthe county of Mahomng and State of Ohio, has invented certain new and useful Improvements in Methods of Pre ring Pickled Steel Sheets, of which the 0 owing is a s ecification This invention relates to the treatment of iron or steel, or articles having surfaces of iron or steel. The principal ObJGGt is to provide a treatment for steel sheets with a-wet solution, adapted to render the articles capable of resisting stains and oxidization and passing to drying rolls in a moist condition.
Another object of the invention is to provide a treatment, which will materially. lessen the labor required in treating iron or steel in this manner.
Another object of this invention is to provide a treatment, which will practically eliminate the need of brushing of steel plates after going through my treatment.
It is now common to the industry of preparing steel sheets to use means of brushing the plates, in order to remove foreign substances before the sheets are introduced to what is known as drying rolls.
A- still further ob ect of the invention is to provide a means oftreatment, whereby, the steel sheets so treated may be taken directly from the last bath of my improved treatment and introduced to an ordinary galvanizing process.
he common method of treating steel sheets now known to the trade, consists in assing the sheets through a sulphuric bath, ollowed by -a water bath, and then into a bath containing muriatic acid.
My methods of treating sheet steel isto, first, introduce the sheets to a hot solution of sulphuric acid, followed by being taken into a water bath. The next step is to place the steel sheet into a special solution to free 23, 1928. Serial No. 676,566.
it from stains and foreign matter, and to otherwise, treat the surfaces for the pur-' pose above mentioned. This solution or reaction products formed by the followmg The next step is to introduce the sheet, thus treated to a hot spra to clean the sheets just before entering w at is known to the trade as dry rolls, for the purpose of thorough] drying the sheets. It will be seen that y this method the old method of sending the steel sheet through the muriatio acidtank before entering the dry rolls, has been eliminated.
What I claim is 1. The treatment of iron, steel, or articles having the surface of iron or steel, which comprises the subjecting of the same to the action of sulphuric acid bath, followed by a water bath, then introduced to a liquid, consisting of: sulphate of zinc, oxide'of zinc, permanganate of potash, water, sulphuric acid, muriatic acid, substantially .as described for the purpose set forth.
2. The treatment of iron, steel, or articles having the surface of iron or steel, for the purpose of preparing said surfaces for metallic coating, comprises subjecting the same to the action of: sulphate of zinc, 4 lbs., oxide of zinc, 4 lbs., permanganate of potash, 1 lbs, sulphuric acid, 75 lbs, H
muriatic acid, 14 lbs.,'water, 100 gallons.
In testimony whereof I aflix my signature. I
