How to calculate Heat loss by radiation in cooling of hot metal by natural air cooling? I want to calculate the heat lost by hot metal put in a mould, to the air. The surface temp of the hot metal drops from 1400 °C to 900°C in this while. There is only natural air cooling in the process. Ambient temperature is 35°C. How should i approach this?To be specific this is the air cooling in the Pig Casting Machine.

You should be having the emissivity value and the dimension of it. Then we can calculate the heat by radiation
