What are the raw materials fed into the blast furnace?
The raw materials fed into the blast furnace typically include iron ore, coke (a form of carbon), and limestone. Iron ore is the primary source of iron, coke acts as a fuel and reducing agent, while limestone helps remove impurities during the smelting process.
What are the proess of iron production in blast furnace?
First we add the basic iron production elements (i.e, limiston,coreand processed iron e.g hematite,Fe2O3 ) the coke is react with oxygen and form crbone monoxide the limestone decomposed to CaO and carbon dioxide,CO2 carbondioxide,CO2 react with Fe2O3 to form Fe and CO CaO (reaction flux) react with almunia and silica form slag the Fe is removed as a molton ways below blast furnace and sage is removed anather ways,THANK YOU FOR READ
Which is the finest iron ore with a very high content of iron up to 70 percent?
hematite with 66% iron in it. In olden days haematite is directly fed into the blast furnace
What is the equation for combustion efficiency of natural gas burning furnaces?
The equation for combustion efficiency of natural gas burning furnaces is typically calculated as: Efficiency = (Energy output / Energy input) x 100% where Energy output is the heat released by burning the natural gas, and Energy input is the total energy content of the natural gas fed into the furnace.
What is an oxygen fed-fire?
An oxygen-fed fire is a fire that is fueled by an increased supply of oxygen, resulting in a more intense and faster-burning fire. It can be more difficult to control and extinguish due to the higher oxygen levels supporting combustion.
What are the raw matierials fed into in the iron works?

Electric arc furnace how is it charged?
There are several ways of charging the Electric Arc Furnace(EAF). 1. 100% Scrap Charging by opening the furnace roof and introducing scrap bucket into the furnace shell. In this process 2-3 charges are taken for reaching the designed capability of furnace. This results heat loss when roof is opened. 2. In latest process DRI/Sponge Iron is fed from roof hopper, continuously, into the molten metal pool. 3. In another process, hot metal(from blast furnace) is introduced from slag door or roof top. This is the most effective method for reducing Tap To Tap Time(TTTT).
What is the biggest impurity in the extraction of iron?
The problems that iron impurities can cause in a blast furnace can include the iron not melting down correctly, obnoxious fumes being created, and the impurities could ruin an entire batch of melted iron.
What are three word forms of feed?
fed fed feeding
Which is the finest iron ore with a very high content of iron up to 70 percent?
hematite with 66% iron in it. In olden days haematite is directly fed into the blast furnace
What is an up flow furnace?
An up-flow furnace is a heating device that draws in air from near floor level in a building, heats it and then discharges the warmed air through a vent or plenum at the top of the machine. The warmed air is then fed into ductwork that distributes it throughout the building. This type of furnace is useful for installation below the area to be heated.
Why is a blast furnace called a blast furnace and not a furnace or fire furnace?
The basic concept of a blast furnace hasn't changed in more than 100 yrs. Modern furnaces are of course more complex due to newer technologies. First of all the furnace is basically a steel tank, inside it is lined with brick or gunite. The outside shell is protected from the heat by hundreds of "coolers" which are located around the entire furnace. Coolers are usually made from copper and have water inlets and outlets; water does not enter the inside of the furnace but is circulated in a closed loop system through a network of piping. At the bottom of the furnace are openings called tuyeres (ta-weers) through which hot air is blown into the furnace. The tuyeres are connected to a large brick-lined pipe called a bustle pipe. The bustle pipe is connected to a series of very large stoves. Outside air is fed into the stoves where it is heated. The heated air is then blown into the bustle pipe, through the tuyeres and into the furnace. The tuyeres can also be piped to allow the use of oxygen, pulverized coal, and natural gas to enhance the heat. Raw material is loaded into the top of the furnace by conveyor or a skip car which runs on a track pulled by cables. The raw materials are iron ore, limestone, coke and alloys chosen by the steelmaker. At the bottom of the furnace is an opening called the tap hole. The tap hole is plugged by a machine called a mud gun, the mud gun is loaded by hand with "mud" which is a high grade refractory that does not melt under the intense heat. After the materials reach the desired temp (usually about 3500 deg F) another machine called a tap drill drills out the mud to let the molten metal out of the furnace; this is known as "casting". Molten metal and slag are separated by a series of channels, slag (girl) will flow to a pit or slag car to be carried away. The slag is cooled to be used in a variety products such as an additive in concrete. The metal is channeled to bottle cars to be transported to different areas of the mill for processing. This is a very basic overview of a blast furnace, they are highly complex and very dangerous!
How does breakfast help with short term memory?
Breakfast basically starts the fire in your inner furnace, including your brain. Your brain has been fed and is active, including memory functions.
