REVERSIBLE BASE PLATE FOR CASTING STEEL INGOTS IN MOLDS Filed June 12, 1934 Fig. I

Patented Apr. 16, 1935 UNITED STATES PATENT OFFICE REVERSIBLE BASE PLATE FOR CASTING STEEL moors IN MOLDS Application June 12, 1934, Serial No. 730,242
In Germany January 12, 1933 1 Claim.
Reversible base plates for casting steel ingots in molds are known. These base plates are, however, open to the objection that the vents for the runner bricks, the stand pipe and in conjunction herewith also the places for setting up the molds, are directly opposite one another. Consequently the plates must be considerably thicker so that they are much heavier, and the desired object, namely saving, becomes to a great extent illusory. Moreover, even if made of greater thickness, the plates retain the very serious inconvenience that, when reversed, the above mentioned opposite, already very delicate portions of the plates cause flaws and fractures, especially the portions on which the chills are placed, on which portions the liquid steel gradually eats away the material and forms recesses, are very detrimentally afiected, or weakened or even become brittle on the side first used, owing to the heat radiated therethrough by the casting. Further, the known plates are very unpractical because their surfaces are not fully utilized and thus large portions of the plates remain unused.
All these objections are overcome by the doublesided base plate according tothe invention.
An embodiment of the invention is illustrated by way of example in the accompanying drawing in which:-
Fig. 1 shows the base plate in plan view.
30 Fig. 2 is a side elevation of Fig. 1.
According to the invention the base plate I which, although made only slightly longer, can be used on both sides, has channels 2 and 3 in each surface. The channels in the one surface are slightly displaced with regard to the channels in the other surface so that the recesses for the runner bricks and the stand pipe in conjunction with the places for setting up the molds are not directly opposite on the upper and lower sides of the plate so that this place can be utilized to much better advantage than the hitherto known 5 two double plates. The base plate according to the invention is further not thicker and only slightly heavier than a one-sided plate. Another advantage, which is of great importance chiefly for obtaining a life twice as long as a one-sided 10 base plate, consists in that the very delicate portions for the recesses of the channel bricks and the stand pipe and the places for setting up the molds are, when the plate is reversed, not afiected by the heat radiated therethrough by the cast- 15 ings. carried out on the side first used, but come to rest on places which cannot be influenced from the other side and are just as durable as those on the first side so that the life of the plate is prolonged to an extent hitherto unattainable and the best utilization of the two-sided base plate is obtained, this representing an enormous continual saving in the consumption of base plates so that a further means has been found for efiecting a very considerable reduction in the cost of production of steel.
The invention can be used in like manner for casting steel ingots and blooms in several rows and in large quantities.
I claim:-
A reversible base plate for casting steel ingots in molds having channels for the rmmer bricks and the stand pipe arranged mutually displaced in its upper and lower sides.
