1 Claim.
This invention relates to metallurgy, one of the objects being to enable the production of an alley or modified metal having a more exactly determinable chemical analysis than is atiorded by the prior art teachings.
A specific example of the invention is illustrated by the accompanying drawing, in which:
Figure 1 is a side view; and,
Figure 2 is a cross-sectional elevation on line 11-11 01' Figure 1.
More specifically, the drawing shows a conventional molten steel ladle I with its rests 2 resting on the centers 01' parallel structural beams 3 whose ends are supported from the floor by short columns 4 and which are centrally provided with fixedly positioned lugs 5 embracing and centering the rests 2. A pit 6 is formed in the floor supporting the columns 4 to provide room for the ladle I and to permit the use of columns of conveniently restricted lengths.
Since the ladle is mounted by the tops of the beams 3, the bottoms of the latter are placed under tension by the weight of the ladle, and this tension is transmitted of lugs 8 welded to the bottom of the beam and to the rod 7, these lugs 8 being equally spaced to either side of the center of the beam.
It follows that the Application April 23, 1938, Serial No. 203,922
steel to be alloyed can be poured into the ladle I and its exact weight determined by observation oi the milliammeter I2, it being understood that the weight 01 the ladle I must be deducted from the total reading obtained. This information permits the calculation of the exact weight of alloying substance which must be added to the steel in the ladle to produce an alloy of the desired chemical analysis, due regard being given to vaporization losses and the like.
ward movement and mounting said ladle between said positions so as to flex downwardly in a curve between said position w rod is also placed in tension so as to strain, and a strain gauge worked by said rod, whereby the degree said rod is strained by tension ALBERT A. FREY. EDWARD J. PARSONS.
