Abstract
PURPOSE: In sintering raw material, fine granules less than 1 mm is controlled in acidity, whereby the reduction strength and sintered ore and NOx generation are controlled to a desired value heretofore unattainable.
CONSTITUTION: It has been found that the acidity (CaO/SiO) of sintering raw material affects sintered reduction strength and NOx generation as shown in the figure, in which the reduction strength indicates the resistance against pulverization in a reducing atomosphere at 500 to 600°C. In sintering operation, NOx generation in exhaust gas and reduction strength of product are first observed, then the curves in the figure are used to shift these values to a desired value. For example, if NOx generation is too high, the acidity in part of less than 1mm in the raw sintering ore is incresed. If the reduction strength is too low, the acidity in part of less than 1mm in the raw material is reduced.
