Batch of required metal charge materials weighed and weighted for the intended chemical composition.

For cast iron alloys the charge commonly comprises pig iron, recirculation material and scrap steel. The more precise and accurately the charge is calculated and composed, the lower is the requirement for subsequent melt corrections.
