Indeed, that is a pretty accurate description. One of the notable things about bloom iron is that the iron does not achieve a molten state in the smelting process - we couldn't reach those temperatures until the industrial revolution.
The English were producing cast iron cannon in the 1540s, and the Chinese were producing a wide range of cast iron objects long before then. According to Technology in the Ancient World, the earliest known Chinese cast iron object dates from about the fourth century before Christ. That is just a little bit before the Industrial Revolution. If you check either Edwin Tunis's Colonial Craftsmen or Jack Coggins's Ships and Seaman of the American Revolution, you can get a very nice cross section of a colonial furnace producing cast pig iron in ton quantities.
