1. In a process for producing pig iron by reducing iron ore concentrate in which solid pre-reduced iron ore, coal, oxygen gas, and slag formers are injected beneath the surface of a molten iron bath contained in a reactor vessel, and react to produce said pig iron, slag, and exhaust gases including CO 2, CO, H 2 and H 2 O, the improvement comprising:

Oct 07, 1996 In accordance with the above, the present invention provides a process for converting iron oxide containing ore fines into pig iron, comprising the steps of introducing said fines into at least one fluid bed reactor, partially reducing at least a portion of the fines by exposing them to a reactant gas in the fluid bed reactor, disposing at least a portion of the partially reduced fines in a charging device

Using water-powered bellows, a large and consistent volume of air created enough heat to completely melt the ore from which iron was made. The technology created two major developments in iron production. First, blast furnaces were now able to make cast iron for the production of hollowware such as pots and kettles

Oct 23, 2017 The process of manufacturing pig iron is a bit complicated. The following steps explain the same as simply as possible. Raw Materials-. The raw materials used in the blast furnace to produce high-quality pig iron are iron-ore, coke, limestone, and sinter

Iron ore is combined with charcoal in a blast furnace to create pig iron. The process of pig iron production involves the combination of iron ore, charcoal, and an intermediary material known as a flux inside a blast furnace. As the materials combine with intense heat, much of

How to Manufacture Pig Iron: How Pig Iron is made? Following three distinct operations are involved in the manufacturing process of pig-iron:. The iron ores as obtained... The crushing of ores helps in two ways:. If ores contain clay, loam and other earthy matter, they are washed in a stream... In

Pig iron is the basic building block of all ferrous metals. It is formed when iron ore is refined in a furnace in the presence of charcoal, limestone and air. It is the basic form of iron used to make decorative wrought iron items. When the pig iron is further refined and a minimum amount of carbon is added, the crystalline structure of the metal changes and steel is produced

Introduction. Iron making evolved over a few thousand years. Using the ancient bloomery method, iron ore was converted directly into wrought iron by heating the ore while at the same time melting the ore's impurities and squeezing them out with hand hammers. This is also called the direct process. By the 1100s water-powered hammers replaced

Oct 23, 2017 The pig iron itself does not have much use but it finds a great number of applications when converted into steel alloys in the steel industry. The process of manufacturing pig iron is a bit complicated. The following steps explain the same as simply as possible. Raw Materials-The raw materials used in the blast furnace to produce high-quality

Pig iron is produced by smelting or iron ore in blast furnaces or by smelting ilmenite in electric furnaces . Pig iron is supplied in a variety of ingot sizes and weights, ranging from 3 kg up to more than 50 kg. The vast majority of pig iron is produced and consumed within integrated steel mill complexes. In this context the term “pig iron

Nov 01, 2017 Once the pig iron ore has been produced it is sent to an basic oxygen furnace, or BOF, to turn it into steel. Molten iron from a blast furnace is “charged” (poured from a ladle) into the BOF

A process for producing pig iron from iron ore fines wherein the fines are partially reduced in a fluid bed reactor and, without pelletizing, briquetting or otherwise agglomerating the partially reduced fines, injecting them with a lance below the surface of a bath of a submerged arc furnace

The first stage is to produce pig iron in a blast furnace.5. The second is to make wrought iron or steel from pig iron by a further process.To make iron, you start with iron ore. Iron ore is simply rock thathappens to contain a high concentration of iron.Common iron ores include:Hematite - Fe2O3 - 70 percent ironMagnetite

The pig iron is obtained from the iron ores in the following steps: 1. Concentration. It is the process of removing the impurities like clay, sand etc. from the iron ore by washing with water. 2. Calcination or roasting. It is the process of expelling moisture, carbon dioxide, sulphur and arsenic from the iron ore by heating in shallow kilns. 3
