Blast furnace – A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally iron, but also others such as lead or copper. The end products are usually molten metal and slag phases tapped from the bottom, the downward flow of the ore and flux in contact with an upflow of hot, carbon monoxiderich combustion gases is a countercurrent exchange and chemical reaction .
Mar 03, 2014· Blast furnace. In contrast, air furnaces (such as reverberatory furnaces) are naturally aspirated, usually by the convection of hot gases in a chimney flue. According to this broad definition, bloomeries for iron, blowing houses for tin, and smelt mills for lead would be classified as blast furnaces.
If the GGBFS is ground by itself, it can be blended mechanically with cement at the cement mill to make ASTM C595, Type IS, Portland blastfurnace slag cement, or it can be added at the concrete plant to make slag concrete.
