Latest Patents

Chitose Shiotani holds a patent for a process titled "Process for producing cold-bonded iron ore for use in a blast furnace." This process involves creating non-fired iron ore that is introduced as a charge into a blast furnace. The iron ore contains 10 to 70% of particles with diameters ranging from 1 to 10 mm. The material is molded into a block using methods such as pressure-molding, shock-molding, or packing-molding with vibrations. After molding, the block is cured or hardened and then crushed to achieve a predetermined shape. Additionally, additives like CaO, Al₂O₃, or MgO can be incorporated to adjust the basicity of the mixture to a range of 0.8 to 2.0. The molding step is designed to ensure that the final product has a void volume equal to or less than 25%.
