Any changes on tap hole clay should be designed based on three key performance concepts: High resistance to corrosion and erosion to ensure long casting durations and uniform casting rates; good adhesion to the blast furnace inner wall to promote stability; and necessary plasticity to facilitate efficient pushing/drilling.
Consequently, the porosity and water absorption are much lower than those of ACBFS or expanded blast furnace slag. Pellet sizes range from 13 mm (1/2 in) to 0.1 mm (No. 140 sieve size), with the bulk of the product in the …
A small portion of non-ferrous slags (e.g. copper) is converted to abrasive materials or grinding media in mills, the majority are stored in slag yards or landfilled.

10.2.2 Blast furnace slag. Blast furnace slag (BFS) is a by-product from iron production in blast furnaces, which are fed by a mixture of iron-ore, coke and limestone. In the process, the iron ore is reduced to iron while all remaining materials form the slag, which is tapped off as a molten liquid and cooled.
