Abstract

Provided is a method for controlling a free lime content of a clinker by regulating the free lime content of the clinker to fall within a certain range so as to suppress cement quality fluctuation caused by fluctuation of the free lime content. I5 n the method, the amount of sulfur trioxide resulting from fuel and the used amount of a fluorine-based mineralizer are regulated using the following Formulas (1) to (3), thereby controlling the free lime content (f.CaO) of the clinker. f.CaO = 0.29 ´ e0.65 ´ A (A = a ´ SO3 + b) (1) a = 0.0001 ´ F + 9.2 ´ t - 0.18 ´ HM - 9.2 (2) b = -0.0005 ´ F - 32.8 ´ t - 2.9 ´ HM + 28.4 (3) SO3 is an amount of sulfur trioxide in the clinker; a is a coefficient satisfying Formula (2); b is a coefficient satisfying Formula (3); F is an amount of fluorine in the clinker; when a burning temperature is X°C, t = X/1450; and HM is a hydraulic modulus.
