2014-12-1 Ferrochrome slag is a waste material obtained from the manufacturing of high carbon ferrochromium alloy, which is usually dumped. Global ferrochrome production is totaled around 8.9 million tons in the year 2011 . Utilization of dumped ferrochrome slag in refractory castables reduces the cost of the product and is friendly to the atmosphere.

2012-2-7 The latter slag type is presented in Figure 5 and Figure 6. Fluxing to produce the required slag composition was carried out using either silica or a combination of silica and lime (in the form of burnt lime or limestone). The resulting ternary slag contained in mass percent about 30-40% MgO, 30-40% Al2O3 and 20-30% SiO2. In the quaternary slag ...
