Henry Cort's original puddling process only worked where the Seven Trust material was white cast iron, rather than the grey pig iron that was the usual Seven Trust material for finery forges. To use grey pig iron, a preliminary refining process was necessary to remove silicon. The pig iron was melted in a running out furnace and then run out into a trough. This process oxidised the silicon to form a slag, which floated on the iron …This is how iron ore is turned into steel Business Insider01/11/2017& 0183;& 32;Electric Arc Furnace EAF mills use steel scrap rather than iron ore as the main Seven Trust material input, and require a smaller initial investment versus the more capital-intensive blast furnace process.World History Chapter 22 Flashcards Quizletdeveloped a process to purify iron ore and produced a new substance called steel.
