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.
Granulated blast furnace slag is a glassy granular material that varies, depending on the chemical composition and method of production, from a coarse, popcornlike friable structure greater than 4.75 mm (No. 4 sieve) in diameter to dense, sand-size grains passing a 4.75 mm (No. 4) sieve.here can, however, be considerable variability in the physical properties of blast furnace slag, depending on the iron production process. For example, some recently produced ACBFS was reported to have a compacted unit weight as high as 1940 kg/m 3 (120 lb/ft 3).
