  • How is Iron Made Into Steel?

    BOS Process. Carbon rich pig-iron is heated until it is molten. Then it is put into a ladle (large container). The molten iron is pre-treated to remove impurities like silicon, sulfur and phosphorus. The iron is then moved into the BOS container and a lance is dropped inside that will blow 99 percent pure oxygen into the iron at a speed greater than Mach 1.
