What are the 2 liquids that are tapped off from a blast furnace?
The two liquids tapped off from a blast furnace are molten iron and slag. Molten iron is the main product, while slag is a byproduct that is formed from impurities in the ore.
What kind of fire bricks are used for molten blast furnace slag?
High alumina fire bricks are commonly used in applications involving molten blast furnace slag due to their high refractoriness and resistance to thermal shock. These bricks are able to withstand the high temperatures and harsh conditions of the slag without deforming or deteriorating quickly.
Which material formed during smelting is denser molted metal or slag?
The molten metal is the denser material, the slag floats on top of it and can be "scooped" off during the smelting process.
Does iron ore slag sink to the bottom of the blast furnace?
Slag is the waste which is skimmed off the top of the molten iron that comes out of the blast furnace. It is a mixture of calcium and magnesium compounds, plus other impurities such as iron oxide, but is mainly calcium silicate. The formula for calcium silicate is CaSiO3.
What is the purpose of limestone in the blast furnace?
Limestone is added to the blast furnace as a flux material. It helps to remove impurities in the iron ore by forming a molten slag that floats on top of the molten iron. This slag can then be easily separated from the iron.

What is added to remove rocky waste and it forms molten slag?
Limestone

Gold or silver bars how do you remove the slag?
To remove slag from gold or silver bars, you can heat the bars in a furnace until the slag becomes molten. Then, you can carefully pour off the slag, leaving behind the purified metal. It's important to use proper safety gear and follow appropriate procedures when handling molten metals.
What is slag powder?
Slag is the unwanted stuff that floats on top of molten metal. It is often glassy. My house has slag powder as insulation in the floors (it was built in 1940 and there was (and still is) an iron foundry in the town.
What is a word for molten metal scum?
Dross is a term used to describe impurities or scum that float on the surface of molten metal.

Why limestone is used in the blast furnace?
Limestone is used in the blast furnace as a flux material to help remove impurities such as silica, which would otherwise form a slag that interferes with the smelting process. When limestone is added, it combines with the impurities to form a molten slag that can be easily separated from the molten iron.
What is slag from welding?
Slag is the residue left on a weld bead from the flux. It shields the hot metal from atmospheric contaminants that may weaken the weld joint. Slag can also be globules of molten metal that are expelled from the joint and then re solidify on the metal surface. in either case, they are usually chipped away with a slag hammer.
What is added to the flux and form a slag?
Common additives to the flux, such as limestone or silica, react with impurities in the metal to form a slag. This slag helps to remove impurities from the metal during the refining process and is then removed from the surface of the molten metal.
How is slag formed?
A slag is a girl who sleeps around with girls and wears revealing clothes and wears padded push up bras. They two time and wear a lot of make up to get attention form males, males often think of them as easy and have very little respect for them and only use them for sex and blow jobs. e.g. ramanSo if you do the above you are classified as a slag
