Green Pellet
While the bentonite addition decreased, the drop number and thermal shock temperature of green balls improved by 0.9 times/0.5 m and 150 °C, respectively. This has resulted in an improvement in the overall iron grade of fired pellet by 1.02% and in CCS by 1000 N per pellet (Liu et al., 2005; Zhu et al., 2009).

In a 4%C, iron alloy, the maximum solubility is 1.80% at 2600 F. Silicon is surprisingly less effective than carbon since the addition of 3% Si to the above alloy raises the solubility to 2.3% Mg. Some high (2%) Mg iron silicon carbon alloys were frozen and then used as addition material.
