  • SteelmakingWikipedia

    Steelmaking is the process of producing steel from iron ore and/or scrap. In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of

  • Direct reduced ironWikipedia

    Hot-briquetted iron (HBI) is a compacted form of DRI designed for ease of shipping, handling and storage. Hot direct reduced iron (HDRI) is DRI that is transported hot, directly from the reduction furnace, into an electric arc furnace, thereby saving energy. The direct reduction process uses pelletized iron ore or natural "lump" ore.

  • How clothes iron is madematerial, history, used, parts

    As each subassembly of the iron is manufactured, the pieces are checked for correct functionality. During the assembly process, an iron is removed from the production line and taken apart by an independent department to look for errors. Any mistakes result in the whole batch of irons being checked and corrected if necessary.
