Latest Patents

Takusagawa holds a patent for a carbon refractory designed for blast furnaces. The patent describes a method for manufacturing an artificial coarse-grain aggregate with a particle size of 1-5 mm. This aggregate is created by adding alumina particulates to prevent molten iron erosion, metallic silicon particulates to reduce pore size, and an organic binder to flake graphite or artificial graphite. The process involves kneading, molding, baking, crushing, and screening. By using this newly manufactured coarse-grain aggregate instead of conventional materials, large-sized carbon refractories with high thermal conductivity and resistance to molten iron can be produced at high yields. These refractories serve as effective lining materials for the basin parts of blast furnaces.
