Show I Tuesday, December 31, 1957 THE DRAGERTON TRIBUNE Page Six Dogwood Type Sandwiches Formed used in aircraft and missiles, wide sheets offer a significant saving in weight, plus design and fabrication simplification. A typical steel Dagwood consists of two carbon steel cover plates each one inch thick. Between them goes a filling of four stainless, steel plates each 516-inct- i thick and treated with a separating compound. The sandwich is held together with welded-i- n side and end bars. Prior to rolling, the sandwich is about three in. thick. Heated to jhigli temperature the sandwich is put through a rolling mill at Homestead District Works. Reduced each time it passes through- the massive rolls, the sandwich becomes progressively thinner, longer and wider until it is a plate approximately 38-inc- h thick, 100 inches wide and 250 . Steel PITTSBURGH, Pa. the famed of prototypes Dogwood sandwich have been experimentally rolled at Homestead District Works of U.S. Steel Corporation, it was announced by President Clifford F. Hood. They are expected to have wide significance "in the aircraft and missile fabrication fields. Results of the research and development project produced the e stainless steel widest world. in The experihe .sheets, ments have achieved a breakthrough in the rolling of stainless and alloy steel sheets and hold promise of adding a new dimension materials to futrue for aircraft and missiles. This has been accomplished y by a "sandwich" rolling process by Howard S. Orr. Through this process, U.S. Steel has demonstrated the feasibility of producing steel sheets' up to 99 inches wide nearly twice the stainless and width of light-gag- e now being made by alloy sheets conventional methods. Translated to terms of aircraft material and design, the wide sheets are ah avenue toward more rapid production and less weight. Where aircraft requirements call for alloy and stainless steel wider than now available, these material limitations require joining of two or more sheets. As more and more alloy and stainless steel is thin-gag- mill-produc- ed - de-velop- ed - inches long. In the rolling process each layer of the sandwich undergoes the same amount of reduction in thickness. Rolled to a total reducthick tion of 90, ,the 516-inc- h reduced stainless steel plates are to a nominal thickness of .033 of an inch each. After cooling, the edges of the htlge plate are trimmed and the thin-gasheets are lifted from atop each other. 4 The sandwich technique, has solved some vexing problems that have prohibited rolling of wide alloy and stainless steel sheets. e sheets For one thing, rolled singly become cool quickly and require tremendous mill power to achieve reduction as the cooling goes on. ge thin-gag- Rooted in Minerals chemically transformed to make list of 'commod-itie- s an in general and an extremdiversified list, ranging from ely drugs to fabrics, and from synthetic rubber to cosmetics.
