A high O2 potential in the steel is beneficial for low N2 levels and the heat should be tapped open as opposed to killing the heat. At 1600 deg C, the maximum solubility of N2 in pure Fe is 450 ppm. Typically, the N2 levels in the steel at tapping ranges around 80 to 100 ppm. Decarburization is also beneficial for the removal of H2.

The starting point for ball mill media and solids charging generally starts as follows: 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 10%-15% above the ball charge for total of 23% ...

The ball charge and ore charge volume is a variable, subject to what is the target for that operation. The type of mill also is a factor as if it is an overflow mill (subject to the diameter of the discharge port) is usually up to about 40-45%. If it is a grate discharge you will have more flexibility of the total charge.
