How iron is made

The Manufacturing Process Charging the blast furnace The melted iron might go to a further alloying process or might be cast into ingots called pigs The slag is carried away for disposal Treating the gases 3 The hot gases produced in the chemical reactions are drawn off at the top and routed to a gas cleaning plant where they are cleaned Get price

What is Sponge Iron? (with pictures)

Aug 31 2019Sometimes known as direct-reduced iron sponge iron is a product that is produced using iron ore The iron ore is often in the form of pellets or lumps and is subjected to a reduction process that is created by the use of a reducing gas that emits from coal or a natural gas source This type of iron can be produced in several different types of furnaces including coke or charcoal ovens Get price
