Iron Processing Britannica

iron processing, use of a smelting process to turn the ore into a form from which products can be fashioned.included in this article also is a discussion of the mining of iron and of its preparation for smelting. iron is a relatively dense metal with a silvery white appearance and distinctive magnetic properties. It constitutes percent by weight of the earths crust, and it is the modern iron making. iron is manufactured in a blast furnace. first, iron ore is mixed with coke and heated to form an iron-rich clinker called sinter. sintering is an important part of the overall process as it reduces waste and provides an efficient raw material for iron making. coke is produced from carefully selected grades of coal.

Steel Basic Oxygen Steelmaking Britannica

steel steel basic oxygen steelmaking: more than half the worlds steel is produced in the basic oxygen process which uses pure oxygen to convert a charge of liquid blast-furnace iron and scrap into steel. the basic oxygen furnace is a refractory-lined, tiltable converter into which a vertically movable, water-cooled lance is inserted to blow oxygen through nozzles at sponge iron, originating from iron ore, namely, silica and alumina and the sulphur and phosphorous contents adversely affect the economics in subsequent steel making operation. therefore, the ore should be high in iron content and low in gangue, physical specification size mm oversize max

Direct Reduced Iron Process Tec Science

In the electric steel process, the sponge iron obtained from the direct reduced iron process is used for crude steel making. In general, scrap is also added to this process as well as pig iron from the blast furnace process. these components are then mixed in a special oven. while the pig iron is already liquid, the sponge iron and the added the process of sponge iron making aims to remove the oxygen from iron ore. the quality of sponge iron is primarily ascertained by the percentage of metallization which is the ratio of metallic iron to the total iron present in the product. sponge iron manufacture is highly sensitive to raw material characteristics.

Steel Making Process Arcelormittal

In the former process, iron ore is the main raw material. In an electric furnace, scrap iron is used and occasionally also sponge iron. sponge is an intermediate product, which is produced from iron ore by means of direct reduction and that is then further reduced and smelted in an electric furnace.sponge iron plant, to produce the sponge iron from iron ore lumps and pellets, to cater to the growing demand for sponge iron in bellary-hospet region of karnataka state. subsequently, due to various reasons, the industry ms. sri subramanya sponge iron pvt. ltd. pre-feasibility report for mini-integrated steel plant of 1,32,000 metric tons

How Sword Making Works Howstuffworks

charcoal is essentially pure carbon. the carbon combines with oxygen to create carbon dioxide and carbon monoxide carbon and carbon monoxide combine with the oxygen in the iron ore and carry it away, leaving a porous, sponge-like mass called a bloom. the bloom was then hammered to remove most of the the bessemer process was the first inexpensive industrial process for the mass production of steel from molten pig iron before the development of the open hearth furnace.the key principle is removal of impurities from the iron by oxidation with air being blown through the molten iron. the oxidation also raises the temperature of the iron mass and keeps it molten.

the process reduces iron ore using a reforming gas made from natural gas. the dri is used mainly as the raw material for electric arc furnaces as a clean iron source substitute for scrap iron. pores are left behind in the dri after oxygen has been removed. these pores, if filled with water, for example, can cause the iron to reoxidize withIn the primary route of steel making iron ore is used as raw material. In the first stage iron ore is melted in a blast furnace to produce hot metal, and in second stage this hot metal is moved to a steel making shop to produce steel in a basic oxygen furnace. In the secondary route of steel making steel is produced using sponge iron, scrap etc.
