This invention relates to the mechanical the interior member being preferably of steel treatment of steel, and has to do particularly and provided with Water cooling conduits.

This rolled stock later requires con- 5 of a material for which iron or steel has siderable rolling whencold, to produce a pol little or no aflinity, which fit around the steel ished surface suitable for highly finished rolls.. As shown, these jackets 4 and .5 are parts such as automobile body sheets, fenders, held in osition by means of the nuts 6 and 75 stock for nickel plating, etc. may be tted in any practical manner and are The present invention relates to the Workformed of a non-ferrous material, preferably ingr or rollingp of steel by rolling or forging bronze, or any material for which iron or instrumentalities having a rollingv or forging steel has little or no aifinityu 3U face which does not have an allinity for the The steel rolls 1 and il may be hollow or 80 ferrous metal.

.. In the particular illustration, Il have shown a pair of rolls for rolling sheet or bar stock,

' gardless of'v their degree of ferrous metals being worked.

but it will be understood thatsuch non-ferrous material may be utilized as the working 'or forming-elementsin any desired type of apparatus Afor mechanically working iron, steel or other ferrous metals. The point being that iron or steel may be reduced and formed without in anyway causing any detrimental' results in the surface due to the aiinity between the working surfaces of the forming means and the'iron or steel being formed and worked, but rather to improve that surface by filling in all the depressions, or rolling down the high points and producing a much more polished condition without the adhesion to the rolls caused by the pres- 'sure on and the affinity of the material' being 'formed or rolled. p

I am aware that attempts have been made to electro-plate rolls with nickel to prevent the forming'of cracks in the rolls, but so far as I am aware I believe I am the first to mechanically treat or work iron or steel by means of working surfaces having no affinity for the iron or steel being worked whereby to produce strips,bars,.sheets, etc., with a polished surface unmarred by the sticking to the-Working or rolling elements.

What I'claim is: 1. The 'method of rolling ferrous metals,

which comprises rolling and forming such ferrous lmetals by relatively moving rolling surfaces'which have noinherent afinity repolish for the 2. The method of rolling ferrous metals, which consists in bringing such metalsto a temperature suiiicent for rolling, and rolling and forming such hot metal by surfaces pf non-ferrous material having little or no inherent aiinity for the hot metal even when such surfaces are not smooth.

3. Apparatus for mechanically treating iron and steel andalloy steel, ycomprising a plurality of rolls ypositioned and 1spaced to t Work and form such metal, said rolls each 4. Apparatus for mechanically treating iron, steel and alloy steels, comprising one or more rolls for working such metal, said rolls consisting of iron or steel over which cylinders revolve in co-ordination, said cylinders formed of a properlyv tempered material which has little or no affinity for iron,

steel and alloy steels regardless of the degree of smoothness of said tempered material.

5. Apparatus .for mechanically 'treating ferrous metals, comprising relatively movable working surfaces for receiving and working said metals, said working surfaces being l formed of a bronze material having little or no aiiinity for the metal bein worked.

In testimony whereof I a si ature;

comprising a jacket or jackets formed er1-. l

tirely of a non-ferrous material over a mandrel formed of ferrous material,`said nonferrous material having `Lno anity for the metal to be treated even when the surface of saidV jacket is not smooth.
