Just out of curiosity, if the molds are made of cast steel, and you are pouring molten

iron into them, which should have the same melting point, what keeps the inner walls of

The melting points of iron and steel are not the same. Iron is around 1700 degrees
fahrenheit, steel is about 2500 degrees f.
