Du får inte något stål ur en masugn, utan bara ett kolhaltigt råjärn eller tackjärn. Ett järn som behöver ytterligare förädling, i sin nuvarande form kan du på sin höjd använda detta till att gjuta dåliga kanonkulor .

Beror ju på vad du smälter eller hur?
Du får ju tackjärn här i väst men så var tydligen inte fallet i Kina.
Du kan ju läsa här vad som smältes ner och vad som hävdades.
Citat:
With no personal knowledge of metallurgy, Mao encouraged the establishment of small backyard steel furnaces in every commune and in each urban neighborhood. Mao was shown an example of a backyard furnace in Hefei, Anhui in September 1958 by provincial first secretary Zeng Xisheng.The unit was claimed to be manufacturing high quality steel.
Huge efforts on the part of peasants and other workers were made to produce steel out of scrap metal. To fuel the furnaces, the local environment was denuded of trees and wood taken from the doors and furniture of peasants' houses. Pots, pans, and other metal artifacts were requisitioned to supply the "scrap" for the furnaces so that the wildly optimistic production targets could be met.
