Definitions

• a wide area of technology The current invention is not available in the area of black metal and is more suitable for alloying with vanadium.
• vanadium For the manufacture of light-alloying vanadium alloys and first of all, pure vanadium is required to protect and equal to the available vanadium oxide, while for the use of iron, vanadium is used. This is the reason for the search for new alloying vanadium-containing materials. Due to this, it was recommended to use vanadium slag, which is obtained by oxidizing 20 vanadium cast iron, as a result of the reduction of vanadium material.
• the slag used here contains a large percentage: iron oxide - 41.6 oxides of oxide - 16.4 oxides of vanadium - 15.8 oxides of manganese - 9.1 30 oxides of titanium - 7.4 oxides of oxide - 2.8 oxides 1.5 metal phase - 8-12 ⁇ mixtures ( ⁇ , ⁇ 2 ⁇ ) - Other. 35 The indicated rule is written in the book of ⁇ .P.
