Construction And Working of Open-Hear Furnace
Points : Construction And Working of Open-Hear Furnace, Definition Definition The open-hearth furnace is a regenerative and reverberatory direct-flame furnace that ranges in capacity up to 350 tons of metal. Depending on the lining of the furnace, the ferrous material produced may be either acid or basic.
The type of ferrous material-melted depends on the chemical compositionf the insulating material of the furnace. The flame in the open-health furnace is directed ‘on to the metal, which is held in a hearth-shaped device encased in an inverted arch. The fuel and preheated air are introduced at one end of the oblong furnace, directed at the metal, and exhausted through the other end of the furnace. Open-hearth furnaces are used to heat large batches of metal and are designed primarily for large tonnages of metal to be melted at one time.
