basic oxygen furnace slag usage in concrete works

Basic oxygen furnace slag - BOS (also called LD-converter slag) is formed during the conversion of hot metal from the blast furnace into steel in a basic oxygen furnace. In this process the hot metal is treated by blowing oxygen to remove carbon and other elements that have a high affinity to oxygen.

Basic Oxygen Furnace (BOF) dust can be mixed with binders to prepare cold-bonded pellets and return to BOF for recycling, because of its high total iron and alkaline oxide content. Nevertheless, the lengthy digestion reaction of dead-burned MgO and CaO contained in BOF dust causes expansion and cracking of the pellets, which seriously affect the pellet strength.

Basic oxygen furnace slags (BOS) are by-products of basic oxygen steel production. Whereas the solubility of some elements from these slags has been well investigated, information about the mineralogy and related leaching, i.e., availability of the environmentally relevant elements chromium (Cr), molybdenum (Mo), and vanadium (V), is still lacking. The aim of this study was to investigate

Steel - Bessemer steel | Britannica

Steel - Steel - Bessemer steel: Bulk steel production was made possible by Henry Bessemer in 1855, when he obtained British patents for a pneumatic steelmaking process. (A similar process is said to have been used in the United States by William Kelly in 1851, but it was not patented until 1857.) Bessemer used a pear-shaped vessel lined with ganister, a refractory material containing silica
