Iron Smelting Essential HumanitiesSteel Basic oxygen steelmaking Britannica

An alloy is formed by mixing a metal with one or more other elements Thus steel and cast iron are actually iron carbon alloys Wrought Iron The earliest type of smelting furnace was simply a pit in the this gives wrought iron its characteristic fibrous composition 1 6 In fact this residual slag is an essential feature of wrought Basic oxygen steelmaking More than half the world’s steel is produced in the basic oxygen process BOP which uses pure oxygen to convert a charge of liquid blast furnace iron and scrap into steel The basic oxygen furnace BOF is a refractory lined tiltable converter into which a vertically movable water cooled lance is inserted to blow oxygen through nozzles at supersonic velocity
