How fine does coking coal need to be ground

  • Coking Wikipedia

    Coking is the process of heating coal in the absence of oxygen to a temperature above 600 °C (1,112 °F) to drive off the volatile components of the raw coal, leaving behind a hard, strong, porous material with a high carbon content called coke Coke is predominantly carbon Its porous structure provides a high surface 展开When caking coals are heated they soften, swell, become plastic, then form lightweight, porous coke particles These coals are also called agglomerating coals (free swelling index of 1 or Coking Coal an overview ScienceDirect Topics2013年4月5日  Coke is required to be strong, with as little degradation as possible, to support the iron ore and coke mix above it in the blast furnace The larger the blast furnace the higher the strength of the coke is needed to Coking Coal IspatGuru2019年1月1日  The operational efficiency of a coke plant depends on three vital aspects: first, the produced coke should meet the quality standards required for the use of modern blast Industrial perspective of the cokemaking technologies
