Steel Making Process
Henry used oxidation to get rid of the impurities in the metal. to do this you would blow air through the metal and it would remove the impurities as a gas or as slag witch can be take from the top. This method was also good because you could add things into the metal like a alloy. this process of making the steel helped the USA tremendously , it helped in the railroad which always need new rails because of the soft metal, and also in bridges because they kept collapsing.
