Metallurgical coke is an important raw material for pig iron production in the blast furnace. During this process the coke undergoes severe mechanical, thermal and chemical stresses. One of these is the CO2 -gasification which may lead to a decisive mechanical weakening of the lump coke by increased carbon burn-off.

The fast heating of anthracite coal and, consequently, the greater release of volatiles may also cause carbon network (or C-structure) fragmentation, resulting in a major increase in the FeO-C reaction rate and the height, as shown in Fig. 11. The same behavior was not observed when anthracite char was added to the same slags.

Anthracite coal typically has moisture content of 3 % to 8 %, ash content of 11 % to 18%, and sulphur (S) content of 0.4 % to 0.7 %. The high variation in ash content translates into wide variations in fixed C content and hence, for use in EAF the ash content is to be kept to a minimum. The ash consists primarily of silica (SiO2).
