Iron is removed from a blast furnace through a process called tapping, where a hole at the base of the furnace is opened to release the molten iron. The iron is then cast into molds to solidify and form pig iron or further processed into steel.
Limestone helps remove impurities (silica, alumina) from the iron ore, forming slag. Coke serves as a reducing agent, reacting with the iron ore to produce carbon monoxide for the reduction process. Iron ore provides the iron for the production of steel in the blast furnace.

Looking in your local Yellow Pages will provide a list of furnace repair companies. You do not need to take the furnace to them, they will come to your home and do an assessment of the damage and give you an estimate of how much it will cost to repair. When calling for repair estimates, make sure that the do not charge for the estimate and only charge for repair work done.
An electric furnace in which the heat is developed by the passage of current through a suitable internal resistance that may be the charge itself, a resistor embedded in the charge, or a resistor surrounding the charge.
Babidi's puppet in season 8, he's a demon.
A cupola furnace is a tall, vertical furnace used to melt iron and other metals. It works by charging alternate layers of metal and coke (carbon fuel) through a charging door at the top of the furnace. The coke is ignited, creating intense heat that melts the metal charge, which is tapped periodically from the base of the furnace.
Submerged Arc Furnace is also called smelting furnace. The furnace is called submerged Arc because Soderberg(Carbon) Electrodes are , buried inside the charge mix. Though Arcing is there but can not be seen. This Furnace is used for producing Ferro Alloys,Pig iron,Silicon metal, Calcium Carbide, Ferro Silicon,Ferro Chrome, Silico Manganese
The charge in the blast furnace typically consists of iron ore, coke (a form of coal), and limestone. The iron ore is the main source of iron, the coke provides the heat and reducing agent, while the limestone helps remove impurities in the form of slag.
there is none, they want charge you for another furnace. there needs to be a class action against Lennox.
If the furnace is lined with refractories and the charge is full a 60% alumina will be 1600C.
