| 434,910. Piling. CONWAY, M. J., 99, South 11th Avenue, Coatesville, Pennsylvania, U.S.A. Nov. 6, 1934, No. 31896. Convention date, Nov. 6, 1933. [Class 83 (iv)] [See also Group II] In the production of wrought iron and articles made therefrom, a substantial amount of a metallic oxide, capable of producing non- corrosive properties, is incorporated in the slag structure during manufacture. Oxides of chromium, vanadium, titanium may be used for the purpose and may comprise 3 to 15 per cent of the slag. In Fig. 1 is shown the iron with equiaxed crystals 1, and slag lamellµ 2 similar to that obtained in ordinary wrought iron practice. In Fig. 2 is shown a structure for piling, having the adjacent edge faces and edges of muck-bars 3 coated with finely divided chromic oxide to provide films 4 between the bars. | ||||||

| An alloy wrought iron contains molybdenum, and may be made by introducing the molybdenum in the form of ferro-molybdenum or a compound such as calcium molybdate, and puddling. The amount of molybdenum in the finished product may be up to 2 per cent. Specifications 131,896, 293,860, and 295,857, [all in Class 82 (i), Metals, Extracting &c.], are referred to. | ||||||

| 344,277. Wrought iron. BYERS CO., A. M., Clark Building, Liberty Avenue, Pittsburg, U.S.A..-(Assignees of Wille, F.; 310, South Michigan Avenue, Chicago, U.S.A.) April 28, 1930, No. 12975. Convention date, Jan. 28, 1930. [Classes 72 and 82 (i).] In making wrought iron by pouring ferrous metal from a ladle 32 into a slag bath 60 as described in Specification 315,827, [Class 72, Iron &c.], the relative positions of the ladle and bath are changed in two planes. The ladle is mounted on a table 31 oscillating round its vertical axis and carried by a platform 30 reciprocating on rails 34 so that the metal falls into the bath 60 along a sinuous path ; and as the ladle is tilted about its horizontal axis, each successive path is displaced from the position of the previous path and no substantial overlapping occurs. These motions are effected by electric motors 37, 44, and 48 reversed periodically to give oscillating motions by automatic switches. The rails 34 rest on a platform scale 35 so that the weight of metal in the ladle is indicated on dial 36. The slag baths 60 are carried by a train of ladles 24 running on a closed track. First the ladles 24 receive slag from a furnace, then pass under one of a battery of pouring ladles 32, then they pass to a press in which the ingot of wrought iron is pressed and slag removed, whereupon they return to the slag furnace. The ferrous metal from Bessemer converters &c. is brought in ladles 61 on carriages 62 and poured into the ladles 32 by means of crane 63. | ||||||

| 224,941. Wade, H., (Byers Co., A. M.). Aug. 14, 1923. Alloys.-Wrought-iron alloys are prepared by adding a small percentage of a metal or metals more oxidisable than the iron e.g. copper, vanadium, nickel, titanium, chromium or manganese to a steel bath before the latter is poured into a molten slag bath to granulate the metal as described in Specification 170,124, [Class 83 (i), Casting &c. metals], the temperature of the molten slag bath being maintained sufficiently below the melting point of the steel during the pouring operation so as to cause the alloy to be granulated as it enters the bath. The desired temperature of the slag bath may be maintained by various methods. | ||||||

| 206,359. James, R. W., (Hibbard Process Corporation). Nov. 6, 1922. Rolling.-Puddled balls are squeezed in a roll and concave surface mill provided with special means for controlling the entry and exit of the balls. The balls are fed on to an inclined table 20, provided with lateral adjustable positioning guides 29, which delivers the ball against the roll. On release of a trigger 22 the table descends into a recess 27 at a rate depending on the adjustable mass 26 and tha ball descends gently into the pass. The concave surface is built up of sections perforated at 16 and spaced at 15 for the escape of slag. The terminal portion of the surface is pivoted at 33, is registered in operative position by a toe 35 during passage of the ball, and afterwards works inwards to form an incline 32 for the discharge of the ball, which is stripped from the roll by a stop 42. In a modification the pivoted section is replaced by a section slotted to pass an ejecting lever. | ||||||

| 189,622. Hibbard, H. D. Oct. 25, 1921. Purifying and refining.- In the production of wrought iron, molten metal and oxidizing agent are poured repeatedly directly from one container to another, air being excluded, in the form of a sheet of molten metal so that by the repeated impact produced by the pouring the iron collects as a ball or bloom the slag remaining in the molten state. The ball or bloom is passed from one container to anotner to expel the entrained slag therefrom and may be discharged to a squeezer or may be rolled while in contact with the slag until it has assumed an elongated shape. During the operation heat is supplied to maintain the temperature until the non-ferrous elements have been substantially eliminated and the iron comes to nature. In making iron of superior quality two slags are utilized, the first being poured off after the bulk of the silicon phosphorus &c. has been eliminated, and then fresh oxidizing material together with a flux added. The process may be carried out in the furnaces described in Specifications 162,624, [Class 51 (ii), Furnaces and kilns for applying &c.], and 179,888. | ||||||

| 178,564. Cliff, R. Jan. 19, 1921. Baling-presses.-Scrap iron is consolidated by compressing with one or more puddled blooms. A charge of scrap is introduced through an opening c into a cylinder a and pushed to the end by a ram b, a bloom is then introduoed and, if desired, further charges of scrap and additional blooms may be added. After compression, the door d is opened and the mass ejected by the ram. | ||||||

| 166,452. Wade, H., (Byers Co., A. M.). July 22, 1920. Purifying and refining.-Wrought iron is manufactured by preheating comminuted or granulated steel in a reducing atmosphere to a point below its welding temperature and feeding gradually into a bath of iron-silicate slag which is at or above the welding temperature. As the steel drops through the bath balling takes place assisted either by hand or mechanical puddling, if desired, the ball being then removed from the bath and treated in the ordinary manner. | ||||||
