The heating of cylindrical billet in annular furnaces in shaft and pipe rolling is investigated. The laws of billet heating and rough-shaft heat treatment are established, as a function of the state of the furnace hearth, the increment of billet supply, and the adjustment of the gas lines to regulate the heating process and ensure uniform heating. Improved conditions for billet heating and heat treatment and the cooling of rolled shafts have been introduced at the 250 shaft-rolling mill at Dneprovsk Metallurgical Works.
