the particle sources can be:

  • melting and refining activities (bf - blast furnace, bof - basic oxygen furnace, eaf - electric arc furnaces), cast house emissions, gas from the top of the furnace during the bf cleaning, oxygen injection and decarburizing phases (primary off-gas emissions), charging/tapping (secondary off-gas emissions)
  • heating and remelt furnaces (depending of type of fuels used)
  • mechanical action (e.g. scarfing, grinding and sand blasting)
  • materials handling (e.g. raw materials, additive, recycled and waste materials, and by-products)
  • coal storage, conveying, charging, coking, pushing, and quenching
  • continuous casting (transfer of molten steel to the mold and cutting of the final product by oxy-fuel torches)
