Development of carbon containing castables for steel ladle
Table 4 shows the PLC value of Al 2 O 3 -MgO-C castables. Increase in graphite content reduced the amount of spinel formation. This might be due to the contact between alumina-magnesia and their mass transition during solid state reaction which was obstructed by the presence of graphite thus the spinel formation took place at higher temperature.
