| 摘要 |
The invention relates to ferrous metallurgy, in particular, to composition of alloy for deoxidation and alloying of steel. An alloy for deoxidation and alloying of steel contains aluminium, calcium, silicon, carbon, barium, vanadium, titanium and iron in the following ratio of components, w/w: 45.0-63.0 silicon, 10.0-25.0 aluminium, 1.0-10.0 calcium, 1.0-10.0 barium, 0.3-5.0 vanadium, 1.0-10.0 titanium, 0.1-1.0 carbon and iron – the rest. The invention provides improvement of quality of deoxidation and alloying of steel with applied alloy due to its purification from oxides, phosphorous and sulfur, and, correspondingly, from nonmetallic in structure and increases of level of its mechanical properties. |
