process to produce steel cutlery from iron ore

Making steel Steel is made from iron ore, a compound of iron, oxygen and other minerals that occurs in nature. The raw materials for steelmaking are mined and then transformed into steel using two different processes: the blast furnace/basic oxygen furnace route, and the electric arc furnace route

    12.5 Iron And Steel Production

    The production of steel in an EAF is a batch process. Cycles, or heats , range from about1-1/2 to 5 hours to produce carbon steel and from 5 to 10 hours or more to produce alloy steel. Scrapsteel is charged to begin a cycle, and alloying agents and slag materials are added for refining. Stagesof each cycle normally are charging and melting operations, refining (which usually includes oxygenblowing)

    In all cases, basic oxygen furnace steelmaking is a method of primary steelmaking that blows oxygen through molten iron ore or coal to lower the carbon content of the alloy and change it into low-carbon steel. The process was developed in 1948 by Robert Durrer, who refined Bessemer steel production by replacing air with oxygen

    This is how iron ore is turned into steel

    Nov 01, 2017 Iron ore, coking coal, and limestone are added into the top of the blast furnace while heated air is blown into the bottom of the furnace to drive the combustion process. The combustion of iron ore with other materials in the blast furnace produces molten pig iron, which is then converted to steel

    How does coke and coal play into steel making?

    Jun 22, 2016 Coke is used as a fuel and a reducing agent in melting iron ore. It is produced by baking coal until it becomes carbon by burning off impurities without burning up the coal itself. When coke is consumed it generates intense heat but little smoke, making it ideal for smelting iron and steel. Prior to the 1880’s, steel was produced using charcoal

    Process. Direct reduction processes can be divided roughly into two categories: gas-based, and coal-based. In both cases, the objective of the process is to remove the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 C (2,190 F))
