Super heat is the temperature of gas above the boiling point of liquid. It is calculated by subtracting saturation temperature from the thermocouple temperature.

See lessFor pure metal super heating can be calculated, for iron and steel it is delicate. For steel casting it is above 50°C of tapping temperature ~1500°C(total) to minimize heat losses while pouring, later carrying laddle to casting moulds.

For pure metal super heating can be calculated, for iron and steel it is delicate. For steel casting it is above 50°C of tapping temperature ~1500°C(total) to minimize heat losses while pouring, later carrying laddle to casting moulds. Now for cast iron it is tedious, since tons of metals to be poured by 30 secs to prevent chilling effects and graphitisation. Experience makes you a good melter!
See lessFor steel casting Superheat is the difference between the liquidus temperature of the liquid steel and the measured liquid steel temperature (Tundish temperature). For steel casting it is above 40-50°C of tapping temperature to minimize heat losses while pouring, later carrying laddle to casting molRead more

See lessSuperheat is the difference between the temperature above the melting point and melting point. Steel is superheated above melting point to compensate for the fall in temperature during transfer and to maintain the good flowability.
