Well, I assume you are talking about Bloom iron and not steel. If you google “ How to make bloom iron “ you’ll find plenty of info and videos. There’s a neat DVD called “From Ore to Axe” by Lee Sauder, Steve Mankowski, and Shel Browder. Steve and Shel are both now retired blacksmiths from Colonial Williamsburg and Lee is known worldwide for his research and production of bloom iron. In the DVD, they make an axe starting with iron ore, transitioning to bloom iron, forging the axe, inserting a steel cutting edge and Shel finally chops a tree.
One other thing - Lee Sauder has a website that includes pages of information including how to make a bloomery. I watched the smiths at colonial Williamsburg make bloom iron a few years ago. Interesting process.
