Sheffield process

A basic open-hearth process using charges so low in sulfur and phosphorus that they could be used in the acid process; the pig iron charged is hematite iron. The charge contains all the elements required to give the required analysis, plus the usual margin of carbon. The charge contains about 0.5% silicon and a maximum amount of manganese, to ensure correct conditions in the bath.
