Black Beauty blasting media is a coal slag abrasive that has low moisture and can be used in standard blasting equipment. This particular coal slag is a fast cutting abrasive because of its sharp angular edges. It is also non-metallic, and chemically inert. Black Beauty has a low dust count and low free-silica.

in a slag-tap furnace, as much as 50 percent of the ash is retained in the furnace as boiler slag. In a cyclone furnace, which burns crushed coal, 70 to 85 percent of the ash is retained as boiler slag (NETL 2006). The American Coal Ash Association (ACAA) (ACAA 2007) estimates that during 2006, the ... More than 85% of the boiler slag is used ...

Abrasive blasting operations can create high levels of dust and noise. Abrasive material and the surface being blasted may contain toxic materials (e.g., lead paint, silica) that are hazardous to workers. Silica sand (crystalline) can cause silicosis, lung cancer, and breathing problems in exposed workers. Coal slag and garnet sand may cause ...

9.5.1 Slag–metal mixing. In steelmaking, slag–metal mixing is a very common phenomenon and it occurs due to the shear at the slag–metal interface caused by excessive liquid steel flow. 37 This mixing leads to emulsification of steel in slag, which increases the total interfacial area and consequently the rate of slag–metal reactions.
