<p>The filler material (2) for the outlet of fusion containers (1) useful in steel industry, comprises a carrier material (95%), which has a grain size of 200 mu m and whose grains are covered with a casing of first and second solid components. Maximally 10 % of the first and second component has grain diameters of greater than 2 mu m and of greater than 90 mu m respectively. The first material constitutes 5-95 wt.% of second component. The maximum grain diameter of the first and second component is smaller than 2 mu m and 90 mu m respectively. The first component consists of soot.

Maximally 10 % of the first and second component has grain diameters of greater than 2 mu m and of greater than 90 mu m respectively. The first material constitutes 5-95 wt.% of second component. The maximum grain diameter of the first and second component is smaller than 2 mu m and 90 mu m respectively. The first component consists of soot, whose primary particle diameter is less than 200 nm. The sum of the components of the casing is less than 5% of the total material. The containers are filled with molten metal or steel. The second component consists of oxide materials and two non-oxidic materials, of which one of material melts at 1400-1650 [deg] C. The oxides are brought as single oxide or as chemical compound into the material. An independent claim is included for a method for production of filler material.</p> |
