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. Dekishev and other "Canada in black metal”. Publishing House “Metallurgy”, Moscow, 1983, p. 36, the same consequence
  • the design is made in the form of two-layer granules with a diameter of 5 metro 5-20 mm.
  • a large amount of carbon was conserved, and the internal layer was completed on a separate basis, which was completed on September 21, 1998.
  • the waste of these products is less than 10 years, and there is a low rate of growth in the metal, which prolongs the process of lightening and lowers the output of the
  • the main task of the invention was to find a material for alloying vanadium, 20 which would increase the energy supply and increase

  • This explosive disintegration of the material significantly increases the reactivity of the medicament to the alloying material and the liquid, as well as to the
  • the positive effect of “encapsulation” of the metallic component of the refractory and mercantile part is acceptable.
  • the size (average diameter) is less than 0.5 mm, the described effect is weaker due to the insufficient thickness of the slump.
  • Oxides which are part of the slavic component of the granule, play a double role.
  • oxides such as iron and brown, create a silica component that accelerates the reduction of iron and vanadium oxides.
