Definitions

  • the present invention relates to carbon-containing pellets for the use as reduction material in electric smelting furnaces for the production of metals and alloys, more particularly for the use in electric smelting furnaces for the production of pig iron, ferro alloys and silicon.
  • Pellets as described above which only contains biomass produced from wood chips and paper, further have the disadvantage that they have a high volume compared to the content of fixed carbon and it is therefore difficult to substitute a major part of reduction material based on fossile carbon with this type of pellets.
  • the biomass is produced by treatment with water vapour under high pressure of a mixture comprising 90 - 99.5 % by weight of wood chips and 0.5 - 10 % by weight of paper, preferably 96 - 99 % by weight of wood chips and 1 - 4 % by weight of paper.
  • Pellets according to the present invention containing 75 % by weight of biomass produced by treatment of 98 % by weight of wood chips and 2 % by weight of paper with water vapour under high pressure and 25 % by weight of particulate coal having a particle size less than 3,8 mm, were examined as to SiO reactivity.
  • SiO reactivity was measured by means of a standardized method where a gas mixture consisting of 13.5 % SiO, 4.5 % CO the remainder being argon, at a temperature of about 1650°C is passed through a bed of the material to be tested. When the gas mixture comes into contact with the carbon material in the bed, more or less SiO(g) will react with the carbon to form SiC and CO- gas. The content of CO in the gas mixture which has passed through the carbon materials in the bed is analyzed and the amount of SiO which has reacted with carbon for the formation of SiC is calculated. Based on this a reactivity number is determined.
  • Pellets according to the present invention containing 60 % by weight of biomass produced by treatment of wood chips with water vapour under high pressure and 40 % by weight of carbon black having a particle size between 200 and 300 ⁇ m were examined as to SiO reactivity using the same method as described in Example 1
  • the result of the SiO reactivity is shown in figure 1 with arrow marked 4.
  • the pellets containing petrol coke according to the present invention show a remarkably high SiO reactivity compared both to petrol coke as such and also to biomass as such.

Abstract

La présente invention concerne des granulés de carbone utilisés comme matériau de réduction dans des processus métallurgiques de réduction destinés à la fabrication de métaux et d'alliages. Les granulés comprennent, d'une part, de 40 à 95 % en poids de la biomasse obtenue par le traitement de copeaux de bois, et éventuellement du papier, au moyen de la vapeur haute pression et, d'autre part, de 5 à 60 % en poids d'un ou de plusieurs matériaux à fines particules de carbone qui contiennent une quantité importante de carbone élémentaire.
