| Hazard Information | Back Directory | [Definition]
The fused substance formed by the action of a flux upon the gangue of the iron-bearing materials charged to a blast furnace and upon the oxidized impurities in the iron produced. Depending upon the particular blast furnace operation, the slag is composed primarily of sulfur and oxides of aluminum, calcium, magnesium, and silicon. | [Flammability and Explosibility]
Nonflammable | [Agricultural Uses]
Blast furnace slag, a by-product in the manufacture of pig
iron from ores, contains a significant amount of
phosphorus. This phosphorus is removed by adding lime
or calcium carbonate to the converter. The phosphorus
oxide formed combines with calcium oxide and silica to
form a slag on top of the molten iron. The slag is then
removed, cooled and powdered and is used for liming
acid soils. Depending on the process of steel
manufacture, the slag is called Bessemer basic slag or
open-hearth basic slag. |
