Rotary Hearth Furnace Iron Direct Reduced Iron. Ironmaking in Rotary Hearth Furnace Ironmaking in the rotary hearth furnace RHF is a direct reduction process which utilizes non-coking coal for the reduction of iron ore. The RHF is the process reactor which consists of a flat, refractory hearth rotating inside a stationary, circular tunnel kiln.
Iron Ore Pellet Plant Burners. Hyl process for direct reduction of iron ore was the fruition of research efforts begun by hojalata y l.Mina, s.A.Later known as hylsa, at the beginning of the 1950s.After the initial evaluation of the concept, it was decided to install a process using a tunnel furnace and several runs were undertaken.
