Blast furnace - Wikipedia
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 being "forced" or supplied above atmospheric pressure.. In a blast furnace, fuel (), ores, and flux are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with,Blast Furnace - an overview | ScienceDirect Topics,Blast furnace gases contain close to 30% CO 2, after full combustion of the CO fraction, while the overall flue gas stream from an integrated steel mill is ∼15% CO 2. The same CO 2 capture options introduced above for power-generation plant can therefore also be applied to a steel mill: • CO 2 capture from the overall flue gas stream •Slag - Wikipedia,Slag is a by-product of smelting (pyrometallurgical) ores and used metals. Broadly, it can be classified as ferrous (by-products of processing iron and steel), ferroalloy (by-product of ferroalloy production) or non-ferrous/base metals (by-products of recovering non-ferrous materials like copper, nickel, zinc and phosphorus). Within these general categories, slags can be furtherGlossary of Steel Industry Terms - American Iron and Steel,,A blast furnace enhancement to reduce an integrated mill’s reliance on coke (because of environmental problems with its production). Up to 30% of the coke charged into the blast furnace can be replaced by this talcum-like coal powder, which is injected through nozzles at the bottom of the furnace.

This is a type of furnace, similar in concept to the blast furnace but very much smaller, that is widely used to produce liquid iron in foundries. It is essentially a refractory lined steel vessel around 6-10 metres high into which cold pig iron, and perhaps some iron scrap, plus coke and a limestone flux is charged. Combustion is assisted by,Steel Slag - an overview | ScienceDirect Topics,Depending on the used production technology, the steel slag can be divided into a basic oxygen steel slag, an electric arc furnace slag and a ladle furnace slag (De Brito and Saika, 2013). The steel slag is used as a secondary cementitious binder, or aggregates for road construction ( Sheen et al., 2013 ; Manso et al., 2004 ).Programmable Fiber Furnace - Rio Grande,The vent-hole with plug allows you to exhaust fumes from the oven.
