Blast furnace iron making is the main method for modern steel production,the process of blast furnace is an important part.

Blast Furnace - ScienceAid

Blasts furnaces are used for smelting during the production of metals such as iron, lead, zinc, and copper. A blast furnace works by blasting hot air up through the furnace while fuels, limestone, and ore move continuously through the top of the furnace. The method used in blast furnaces have been used since the 1500s.


HOW A BLAST FURNACE WORKS Introduction ... Once a blast furnace is started it will continuously run for four to ten years with only short stops to perform planned maintenance. The Process . Iron oxides can come to the blast furnace plant in the form of raw ore, pellets or sinter. The raw ore is removed from the earth and sized into pieces that ...

The chemistry of steelmaking. Blast furnace.

The production of iron in a Blast Furnace is a continuous process. The furnace is heated constantly and is re-charged with raw materials from the top while it is being tapped from the bottom. Iron making in the furnace usually continues for about ten years before the furnace linings have to be renewed.

Iron Ore Processing for the Blast Furnace

blast furnace process. The iron ore concentrate is now mixed and ready for the pelletizing process. Pelletizing A pellet plant contains a series of balling drums where the iron ore concentrate is formed into soft pellets, in much the same manner that one rolls a snowball, to make a pellet about the size of a marble (between 1/4" and 1/2").

Blast Furnace – Official Minecraft Wiki

Blast furnaces are similar to furnaces, but can smelt only ore blocks and tools/armor made of iron, gold or chainmail. Once an item and a fuel are placed into the blast furnace, the block state changes to lit and the item is smelted twice as fast as a regular furnace. Fuel is also used at double the rate of regular furnaces, so the number of items smelted per fuel stays the same.

Chemistry of the Ironmaking by Blast Furnace Process ...

Nov 22, 2013 · blast furnace, CO, Reaction, slag, Chemistry of the Ironmaking by Blast Furnace Process. Liquid iron (hot metal) is produced in a blast furnace from the burden materials through a series of stone reactions which are taking place at various levels in a blast furnace.

Blast furnace - Simple English Wikipedia, the free ...

A blast furnace is usually built with a steel case and bricks made of magnesium oxide or other refractory material inside the case. The hot furnace cannot melt these bricks. The furnace is cooled with water running inside part of the case and bricks. The process of making iron is simple. Iron ore is basically iron oxide. Iron is made by ...

Blast furnace process - tec-science

Combustion process. The iron in the processed ores must be dissolved out by stone processes. This requires an element that binds oxygen more strongly than iron. This is exactly what carbon can do as a reducing agent.The carbon is fed to the blast furnace in the form of coke (pyrolyzed coal) from the coking plant.At sufficiently high temperatures, the carbon can participate directly in the ...

Blast Furnace operation: HOW A BLAST FURNACE WORKS

Aug 04, 2011 · The purpose of a blast furnace is to chemically reduce and physically convert iron oxides into liquid iron called "hot metal". The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom.


Oct 04, 2016 · A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air ...
