In this work, the TA cup method was also utilized to measure the cooling curves of molten slag, as shown in Figure 21. The T L was estimated as 1288 °C (2350 °F) and 1400 °C (2550 °F) for slag A and B, respectively. Obviously, ... Foundry Handbook, Vol. 1, Cast Iron, in Chinese, 2 nd edn. (China Machine Press, 2002), pp. 634-674.
Contamination in the metal rises to the top of the material and is removed as "slag." Cooling systems may be used to accelerate solidification and control metal temperature. ... Elsewhere in the process, foundry managers focus on measurement, especially of energy consumption, as a way to identify further cost and waste reduction ...

[0005] In summary, the foundry slag ladle ...
Cooling in the muller. Although it provides a degree of relief in some systems, most modern foundry engineers view cooling in the muller as an undesirable technical compromise. The process of adding cooling air and fluidizing the sand mass for effective cooling is a direct contradiction to the activities necessary for effective final mixing.
There are 3 types of cooling towers used in direct combination with induction furnace systems (look pages before). a) Dry cooling towers, which work like vehicle radiators with cooling vanes and high air volumes, can be used in … Continue reading Cooling towers ...
