Definitions

  • the invention relates to a blast furnace smelting process, in particular to a process of smelting ferronickel by a blast furnace of nickel oxide ore without crystal water.
  • nickel metal the most important element of smelting stainless steel and special steel
  • the traditional nickel metal production is mainly extracted from the nickel sulfide ore which accounts for 30% of the earth's nickel resources, and its production process is mature.
  • the current reserves are insufficient and resources are in crisis. It is forced to pay more attention to the extraction of nickel metal from the laterite nickel ore (nickel oxide ore) which accounts for 70% of the earth's nickel resources.
  • the solution is separated from the nickel sulfate, and metal nickel is formed by electrolysis to form only 1 to 2% of the total amount, and the remaining components are discarded.
  • the process equipment has large investment, complicated process, long cycle and serious environmental pollution.
  • the use of blast furnace smelting is undoubtedly a more economical choice, but because the laterite nickel ore is often accompanied by Cr 2 0 3 components, and the melting point of chromium is high,
  • the sintered ore is crushed and sieved, and the sintered ore with a particle size of 10 to 50 mm is a smelting raw material of the blast furnace, and the ore powder having a particle diameter of less than 10 mm is re-sintered;
  • Nickel 0. 5 ⁇ 4. 5%
  • the CaO content is greater than 50% limestone, quicklime CaO content greater than 80%, the content of Mg in the dolomite> 10%, in the fluorite CaF 2 content of> 80%.
  • the blast furnace smelting process provided by the invention has low cost, and the traditional ore furnace process requires 2000 to 4000 kWh/ton of iron, and the coke is 0.5 ton.
  • the blast furnace consumes 150 ⁇ 200 in the process provided by the invention. Electricity / ton of iron. Energy saving, large output, average blast furnace output is greater than the average output of the submerged arc furnace. Less pollution and less dust.
  • the raw material recovery rate is high, and the yields are: iron 97 ⁇ 98%, nickel 99%, chromium 40 ⁇ 50%. detailed description:
  • Sintered ore, raw ore, coke, limestone/lime, dolomite and fluorite are mixed and smelted to obtain ferronickel.
