Blast furnace iron making method using low grade iron scrap

摘要

PPROBLEM TO BE SOLVED: To provide a method for producing iron in a blast furnace with which the high-class steel material can efficiently be produced by utilizing a large quantity of low-grade iron scraps mixing non-iron material, such as copper wire, plastics. PSOLUTION: This method is provided with: a low-grade iron scrap manufacturing process for manufacturing the low-grade iron scrap by dismantling the waste, such as waste car, waste building material; a high-grade iron scrap manufacturing process for manufacturing the high-grade iron scrap from the low-grade iron scrap; a high-grade iron scrap-made iron raw material-making process for treating the high-grade iron scrap into for iron-making raw material; and a high-grade iron scrap charging process for charging the high-grade iron scrap into the blast furnace or/and converter, etc. PCOPYRIGHT: (C)2010,JPO&INPIT
