The temperature measurement of cast iron is quite a complex subject. The temperature of a bath of molten metal is by essence not homogeneous. You can have in the same molten bath, discrepancies of temperature that can reach 100°C, due to location and flux motion of cast iron. For this reason, an instantaneous punctual measurement is not the most effective way to appreciate the temperature of molten metal.
FOSECO has developed a range of different technologies for temperature measurement in order to help the foundry man to appreciate his pouring temperature range. These technologies can be applied to a pressurized furnace or bottom pour ladle with various types of cast irons
