<p>Metals are deoxidized by treating them with a very fluid oxide-extracting slag containing not less than 5 per cent and not more than 90 per cent of titanium oxide and acid, neutral or basic oxides usually contained in metallurgical slags and in such relative proportions that the slag has an acid character and is capable of extracting the oxides from the metal treated. In an example, a slag contains 35 per cent of titanium oxide, 25 of silica, 30 of alumina, 5 of lime and 5 of manganese oxide. Specifications 409,911 and 423,732 are referred to.</p> |
