METHOD OF PRODUCING FERRo-slLICo MAGNEslUM ALLOY.
No Drawing. Application filed November 11, 1916, Serial No. 130,908.
Specification of Letters Patent.
Serial No. 443,222.
To allwhom it may concern:
Be it known that We, GUsTAv PISTOR, AL- BERT BEIELSTEIN, and AnoLF BECK, all subjects of Germany and residents of Frankforton-the-Main, Germany, and Bitterfeld, Gen many, respectively, have invented certain new and useful Improvements in the Method of Producing Ferro-Silico-Magnesium Alloy, of which the'following is a specification.
Our invention relates to the production of an alloy containing magnesium and being adapted to be used as a deoxidizing agent for iron and cast steel. The object of the invention is to provide a process of producing such an alloy that contains magnesium and silicon Which latter substance has proved a quality improver of considerable value.
It has been proposed to produce a ferromagnesium alloy by adding magnesium to iron or steel in a semi-fluid state, and to use the alloy thus obtained for the purpose of treating iron or cast steel. It has been further proposed to previously alloy the magnesium With nickel or aluminium, and to introduce the thus obtained alloy into an iron or steel bath, said bath being required to be in semi-fluid state for that purpose. The resulting alloy has been applied for refining iron or cast steel.
l/Vhile trying to introduce, in the same manner, silicon into a magnesium alloy intended to be used for the same purpose of deoxidizing ironor cast steel, We found that the alloying of silicon and magnesium offers considerable difiiculties.
Now, we have discovered that alloys of the desired character can be obtained in a simple and smooth manner by starting with ferro-silicon in a semi-fluid state and adding the magnesium hereto. The magnesium must be added to the ferro-silicon when the latter is in a semi-fluid state, that is, not
completely melted. If the addition of the magnesium is delayed until the terro-silicon is completely melted and thinly fluid, only a small portion of the magnesium will alloy, by far the greater portion being uselessly consumed. Instead of magnesium, alloys of magnesiuinand any other metal, may be introduced into the terro -silicon While the same is in a semi-fluid state, such magnesium alloys, for instance, as magnesium aluminium, or magnesium-nickel. In carrying the invention into effect, a ferro-silicon may be used containing silicon to any percentage, for instance, a ferro-silicon containing from per cent. to per cent. silicon.
For the purpose of effecting a deoxidation of an iron or steel bath,'the thus obtained alloy may be app-lied either in a fluid or in a solid state.
What We claim as our invention and desire to secure by Letters Patent ot the United States, is:
The method of producing an alloy containing magnesium for use as a deoxidizing agent for iron and rest steel consisting in melting ferro-silicon to a semi-fluid state and. adding magnesium thereto while in said state.
In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
