Description
B. TALBOT. BOTTOM PLATE FOR STEEL INGOT MOLDS. V ,701. Patented No'v'.28,1893.
(No Model.)
UNITED STATES PATENT OFFICE.
BENJAMIN TALBOT, OF PENOOYD, PENNSYLVANIA.
BOTTOM PL ATE FOR STEEL-INGOT MOLDS.
SPECIFICATION forming part of Letters Patent No. 509,701, dated November 28, 1893.
Application filed June 22, 1893. Serial No. 478,548- (No model.)
To all whom it may concern;
Be it known that I, BENJAMIN TALBOT, a subject of the Queen of Great Britain, residing at Pencoyd, Montgomery county, Pennsylvania, have invented a Bottom Plate for Steel-Ingot Molds, of which the following is a specification.
My invention relates to bottom steel ingot molds.
In the manufacture of steel ingots as now practiced, when pouring steel into ingots from the top, the molds are placed upon a cast iron bottom plate or stool. When the stream of metal is poured from the top it strikes the plate with great force and owing to its very high temperature it quickly wears holes in or pits the plate to such an extent that a plate plates for cannot stand many castings before it is worn out. In order to lengthen the life of the plate, in some measure, it has been customary to fill the holes or indentations in the plate, with clay or loam to make the surface thereof smooth. When liquid metalis poured in upon a bottom plate so repaired, it generally washes the clay or loam off the bottom and sometimes this material gets into the steel ingot. The presence of this foreign matter in the ingot causes an extra waste when the ingot is rolled or otherwise treated, and the metal is defective whenever it contains such foreign matter. The object of my invention is to overcome this defectin the manufacture of steel ingots, and to produce a bottom plate by which considerable saving in the cost of manufacture of steel may be eifected, and, also which will avoid the necessityof repeated repairs, c.
Instead of having a bottom plate of cast iron, as generally practiced, I make it of slag, such as is obtained as a waste product from acid or basic steel furnaces, converters, blastfurnaces or any suitable slags which are available from other metallurgical processes.
.Other features of my invention will appear in the description and the claims hereinafter set forth.
Referring to the accompanying drawings in which similarletters of reference refer to similar parts, Figure 1 is a vertical section of a bottom plate, with a portion of the mold thereon mounted upon the car. Fig. 2 is a vertical section of a plate inclosed in wrought iron or steelirame.
In all the figures, A represents the body of slag or equivalent waste product; B, the sur rounding frame which is made of any suitable shape or size, and may be flanged, as shown, or not as desired.
H is a hole in the side of the framethrough which I preferably pour the liquid slag in making my bottom plate, as more particularly described hereinafter.
D represents a portion of a mold mounted upon the bottom plate, and (J, the car body upon which the above parts are shown mounted, and E, the flange upon the said car body.
I have obtained very good results with slags obtained from acid and basic open hearth furnaces. When using these slags I preferably pour the slag in its original liquid condition into a frame of suitable size and shape to form such a bottom plate, as may be desired.
While I preferably use slag obtained as a waste product in making my bottom plate, I do not confine myself to slag thus obtained for oxide of iron, manganese, with or without acid or basic (such as sand or limestone) material can be specially melted and cast into the bottom plates; although this would never be done in works where they had suitable material liquid at no cost, yet they could be made this way and disposed of at a profit.
In order to get a smooth and fine surface upon both sides of the bottom plate,I preforably cast the slag body by pouring the liquid slag through the side of the frame; and to do this I fasten a plate S, by suitable means, upon each side of the frame B, as shown in dotted lines, Fig. 2, and placethis in a vertical position, pouring the molten slag through the hole H. A bottom plate constructed by this method, after removing the plates on either side, presents a smooth surface on both sides and is, therefore, reversible and can be used on both its sides. I
It is obvious that the slag body may be removed from the frame as desired, and another body cast therein.
In Fig. 2 is shown a bottom plate of which the frame is of wrought iron or steel, and in Fig. l, of 'cast iron, but it is obvious thatany suitable material can be employed for this frame.
I sometimes embed in the slag wire rods B,
or other shapes of metal, so as to form acon-.
glomerate mass whereby additional binding of the slag may be obtained; but when this is done care must be taken not to have these rods or binding material near the surface.
By making the bottom plates as I have above described, I not only reduce the cost of manufacture of steel, because part of theliquid slag, which is otherwise thrown to waste, is utilized, but I also efiect a saving by pre- 7 1o venting the waste of that portion of the ingot in which it frequently happensft'here is inclosed some of the loam or clay used on the bottom plates, as herein before described.
While I have shown the bottom plate of rectangular form, it is evident that the form and size, as well as the details of the frame surrounding the slag, may be varied without departing from the spirit of my invention; and of course the bottom plate may or may 20 not be mounted upon the car-as shown.
What I claim isl. The herein described improvement in bottom plates for steel ingot molds, consist- I rounding metal frame, substantially as described.
3. A bottom plate for ingot molds, cons sting of a central body portion of slag w1th w re rods or other metal shapes embedded therein, and surrounded by a metal frame, substantially asdescribed.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
