G. Wallace, in Fundamentals of Aluminium Metallurgy, 2011. 4.3.6 Melting and alloying. The secondary aluminium industry employs a range of furnaces, however the most common is oil or gas fired reverberatory furnaces ranging from 5 to 90 tonnes capacity and rotary furnaces of 2–20 tonnes capacity. Modern plants will utilise efficient oxygen enriched burners for faster melting rates.

The early development of the reverberatory furnace for smelting copper ores was the work of the Welsh smelters, particularly those of Swansea. The first record of a reverberatory furnace is made by Jars, who states that copper-smelting was effected in reverberatory furnaces at Middleton-Tyas, in Yorkshire, England. The first patent, of any importance, for improvements in reverberatory furnaces ...

5/17/2017· 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.
