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
Why did Albert Einstein smoke?
He was bottle fed as a infant
What is an oxygen fed-fire?
An oxygen-fed fire is a fire that has (most likely) pure oxygen fueling it. The air we breathe is composed of around 19% oxygen, therefore by adding more oxygen the fire will get hotter.
Carnivorous birds that fed on organisms exposed to this chemical produced fragile eggs The chemical is?
DDT
In water treatment plant operation does over dosing on filter aid chemicals prevent sealing of filter media?
1. Polymers used as filter aids are similar to flocculants in both structure and function. 2. Filter aid polymers are typically fed at dosages less than 0.1 mg/L; when fed in higher concentrations, they can contribute to filter head loss and short filter run times. 3. Filter aid polymers are fed at a point of gentle mixing (e.g., filter influent trough). 4. Product density and solution strength information can be obtained from the individual polymer manufacturers
What are the raw matierials fed into in the iron works?
a blast furnace

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
What is iron ore lumps and iron ore fines. What is the difference?
· Iron ore fines (less than 6mm) · Sized ore (size 5mm to 20mm) · Lump ore (size 10mm to 40mm) Iron ore fines are created as a result of mining, crushing and processing the larger pieces of ore. The reason lump is preferred is that when it is fed into a blast furnace for steel-making, its particle size allows oxygen or air to circulate around the raw materials and melt them efficiently. The fine iron ore products have first to be processed into what is called sinter, otherwise it will effectively smother the air flow in 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.
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.
What were the two occasions god fed the masses with five loaves and three fish?
Here it was Jesus and not god who fed the 5,000 people.
What are the three basic with holding on a paycheck stub?
Fed, State & SS.
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!
