UNITED STATES SAMUEL T. G. SMITH, OF ST. LOUIS, MISSOURI.
METHOD OF MAKING STEEL, IRON, AND OTHER METAL PLATES.
No Drawing.
To all whom it may concern Be it known that I, SAMUEL T. G. SMITH, a citizen of the United States, residing at St. Louis, Missouri, have invented a new and usefulMethod of Making Steel, Iron, and Other Metal Plates, of which the following is a specification.
This invention relates to a method of making steel, iron and other metal plates or sheets;and has special reference to a method of preventing the plates or sheets from'sticking together when they are folded upon themselves for rolling or piled one on top of the other.
Heretofore in the manufacture of steel, iron and other metal plates or sheets the plates or sheets have been heated and rolled and folded upon themselves, and rolled successively to proper thinness. After the rolled to proper thinness they have been piled or stacked one upon another. As the plates or sheets are very hot it has been impossible to prevent all of the plates or sheets from sticking together, so that they could not be separated without injury to them. The injured plates or sheets could not be used for the purposes for which they were intended without additional handling and treating, so that the costof obtaining creased.
By my present invention'I am enabled to obtain the desirable and beneficial result of preventing the plates or sheets from stick ing during rolling or when they are piled one upon another. I accomplish this result by placing powdered barytes upon the surfaces of the plates or sheets. which prevents perfect plates was greatly inadhesion of the plates or sheets when they are being rolled and when they are piled Application filed June 1, 1925. Serial No. 34,170.
. after having been rolled. The" powdered barytes is placed upon the surfaces of the plates or sheets either'while they are hot or cold and, notwithstanding the intense heat to which the plates or sheets are subjected, the barytes does not produce any injurious effects but prevents adhesion. Its beneficial result is to prevent the plates or sheets from sticking together when rolled, piled, an-. nealed, or otherwise treated.
y my invention I am enabled to reduce largely the,c0st.of producing rolled plates or sheets of iron. steel or other metals. since the damage resulting from the plates or sheets sticking together and the expense of separating the plates or sheets are avoided.
The invention is useful for other purposes, such as preventing adhesion .of cast q ings to mold surfaces or Walls. It also facilitates the Withdrawal of castings from 00 molds. I
I have not attempted to mention all of the useful purposes to which the invention may be applied, but claim the invention broadly for every use.
What I claim and desire ters Patent is 1. The method of preventing adhesion of metal plates or sheets, which consists in applying barytes to the metal plates or sheets.
2. The method of preventing adhesion of metallic plates or sheets which consists in placing powdered barytes upon the surfaces ofthe plates or sheets.
3. The method of preventing adhesion of metallic plates or sheets which consists in placing a quantity of barytes upon the sur' faces of the plates or sheets whenthe plates or sheets are being rolled or annealed.
