摘要： A method of production of cement bonded agglomerated ore not depending on yard curing which can improve the environment, save labor, and improve yield is provided, that is, a method of production of cement bonded agglomerated ore which adds Portland cement as a binder to dust produced from an iron works and/or fine powder ore, treats the same by mixing, moisture adjustment, and kneading steps, then pelletizes it by a pan pelletizer and suitably thereafter cures it to produce blast furnace-use cold pellets or sintering-use minipellets having the required crushing strength, which method charges the raw pellets from the top of a vertical type container and discharges them from the bottom end to form a moving bed and cures the raw pellets in the period from charging to discharging.

摘要： A nonfired agglomerated ore which is satisfactory in reduction property in the shaft of a blast furnace and excellent in rapid heating bursting property and a production method thereof are provided. A carbon containing nonfired agglomerated ore for blast furnace which is prepared in such a way that iron oxide and a carbonaceous material are blended with each other to prepare a mixture, a binder is added to the mixture, and the mixture is kneaded, formed, and cured, wherein the agglomerated ore contains carbon in the content of 80 to 120% of the theoretical carbon quantity required to reduce the reducible oxygen in the iron ores to form metallic iron, and the binder is selected so that the crushing strength may be 7,850 kN/m2 or more at room temperature.
