JAMES HoRNERQOF NEW YORK, N. Y, ASSIGNOR TO HIMSELF AND JOHN ooX, or POMPTON, NEW JERSEY.
Letters Patent No. 104,957, dated July 5, 1870.
IMPROVED METHOD OI ROLLING METAL BARS.
The Schedule referred to in these Letters Patent and making part of, the same.
To all whom it may concern Be it known that I, JAMES Houses, of the city, county and State of NewzYork, have invented a new and useful Improvement in'Rolling Steel, Iron, and other Metals and I110 hereby declare that the following is a full,clear, and exact description thereof, which will enable others skilled in the art to make and use the same.
This invention relates to a new and useful improve: ment in the process of rolling steel, iron, and other metals, more especially designed for steel in the round form, but applicable to other forms,avliereby such steel, or other metals, are produced free from scale in the most rapid manner without the use of oleaginous or lubricating substances, as in the ordinary process pursued in rolling these metals.
The usual method in rolling steelis to take the bar from the reducing-rolls (which contain square grooves) and pass it through oval grooves, and afterward through round grooves when round bars are to be made.
By this method the compression is on all its sides, so that the scale is rolled in excepting in the last passage from the oval to the round grooves, and then there is but little chance for the scale to clear itself.
To render this steel marketable, a slow process of cold rolling is resorted to, involving the use of tallow, or other oleaginous substance, in combination with plumhago, thus materially increasing the cost of the article.
By my process thebars of steel are rolled hot, and delivered from the rollers ready for market.
The process consists in taking the bar from the square reducing-rolls and passing it through fiat rolls,
- which eifectuallyremovcs the scale from the two sides.
The bar is then passed through oval grooves, in doing which'thc two edges of the bar are subjected to all the pressure, which thoroughly removes the scale from the flattened sides. At this stage of the process the bar has become so cold-that no more scaleis produced. Then, by passing it through the round grooves, the bar is finished clear of all scale.
This method of rolling is applicable to steel, iron, and many other metals, and to bars of other than a round form, the main object of the improvement being to avoid rolling in the scale during the process of rolling.
Having thusdesoribed my invention, I claim as new and desire to secure by Letters Patent- The method herein described of manufacturing scaleless round bars of metal readyfor the market, without cold rolling, that is to say, taking .the bar as it comes from the reducing-rolls, and, without reheat in, rolling it out successively between plain rolls, with nothing to confine it laterally, in order to reduce it to a flat shape, then edgewise in an oval groove, to impart to it an oval shape,'and then in a cylindrical groove, to give it thefinished round shape.
JAMES HORNER.
