When the particle size distribution of the inert material is indicated by means of a grain size distribution (fraction), the calculation is made according to formula (1). Furthermore, the addition rate of an inert material with a particle diameter of 3 mm of more or an inert material with a grain size corresponding to a particle size of 3 mm or more is set to be 0.3 wt.% or less based on the total amount of the charge. The addition rate of the inert material is set to be in the range of 1-7 wt.% of the total amount of the charge.
