The authors show that, up to approx. 0.2% addition, Uranium as an alloying element has little improving effect on the properties of carbon steel. Uranium, however, can be used as a great effective deoxidizer or refiner of molten steel, improving the final deoxidation and the steel ingot-making procedures properly, because it has great affinities with oxygen and sulphur, and the specific gravities of it's oxides and sulphides are greater than that of molten steel. For the practical application of uranium in steel making, the authors point out that it is necessary (1) to establish the detailed regulations for handling radioactive substances from the standpoint of practical operation, (2) to develop the method of uranium addition, (3) to clarify the chemical reaction between refractories and uranium, (4) to investigate the deoxidizing and desulphurizing reactions with uranium in molten steel and (5) to establish the manual on disposal and treatment of the refractories worn out, slag and steel scraps.
