They do it all the time, out of the furnace comes crude iron, which then must be moved to the steelmaking plant. It is cast into bars only at the steel plant. The carbon dissolved in crude iron lowers the melting point substantially, it's around 1200 °C, so you can actually transport it in steel vessels.
