For general information about merchant pig iron, please visit the pig iron page. Modern blast furnaces produce more than 10,000 tonnes per day. Blast Furnace Process. The blast furnace is a counter-current gas/solids reactor in which the descending column of burden materials [coke, iron ore and fluxes/additives] reacts with the ascending hot gases.

By vr foundries on 12-May-2018. In this rather short blog let us discuss the three different grey iron casting processes: Die Casting, Centrifugal Casting and Ductile Iron Casting. Centrifugal casting is usually a method employed to cast cylindrical parts and components giving outer surfaces that are finely grained with uniform dispersion.

Billets are semi finished product. We manufacture square billets of size 100*100 sq.mm. We use Induction furnaces and continuous casting machine for billets manufacturing. The process of manufacturing Billets is a two stage process. The first stage consists of feeding M.S. Melting scrap, Sponge Iron, Pig Iron and other alloys in the induction ...

Iron ore is used mostly in pellet and/or lumpy form. Oxygen (O2) is removed from the iron ore by chemical reactions based on H2 and CO for the production of highly metalized DRI. In the direct reduction process, the solid metallic iron (Fe) is obtained directly from solid iron ore without subjecting the ore or the metal to fusion. Direct ...

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. Now, these iron ores are nothing but oxides of iron that contains other materials like ...

You know why a production flow chart is important and you've seen how it works in our example of a production flow chart. Now, let's take a look at how you make a production flow chart. 1. Identify Tasks. First, you have to know all the tasks in the production process, everything from start to finish.

A Process Flow Chart (PFC) in manufacturing is a diagram of the separate steps of a operations/process in sequential order. PFC also known as process flow diagram (PFD), and Process Map.. PFC is a …

Iron making. The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way. A third group …

Before iron ore can be used, oxygen must be removed from it. Known as 'reducing', this can be done either in the blast furnace, where hot air is injected into a continuous feed of coke, sinter and lime, or by the direct reduced iron (DRI) process. The result from both is liquid iron, which is then transported to the basic oxygen furnace. The blast furnace …

DRI production. Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, i.e. without melting, as in the blast furnace. The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal. Iron ore is used mostly in pellet and/or lumpy form.
