A metallurgical furnace, often simply referred to as a furnace when the context is known, is an industrial furnace used to heat, melt, or otherwise process metals. Furnaces have been a central piece of equipment throughout the history of metallurgy ; processing metals with heat is even its own engineering specialty known as pyrometallurgy .
An electric melting furnace. A melting furnace is necessary only when spin casting metal. The metal must be molten prior to introduction into the mold. It is necessary for a spin casting furnace to have a temperature controller, as there is an optimal range for each metal.
Typically a transfer ladle will be used to transfer molten metal from a primary melting furnace to either a holding furnace or an auto-pour unit. Treatment ladle: a ladle used for a process to take place within the ladle to change some aspect of the molten metal. A typical example being to convert cast iron to ductile iron by the addition of ...
The pig iron was melted in a running out furnace and then run out into a trough. This process oxidized the silicon to form a slag, which floated on the iron and was removed by lowering a dam at the end of the trough. The product of this process was a white metal, known as finers metal or refined iron.
The maximum melting area of day tanks is 10 m2, and the melting capacity is between 0.4 and 0.8 t/m2 of melting area. The pot furnace is one type of this. The furnace consists of a refractory masonry basin with a depth of 40 to 60 cm (bottom furnace), which is covered with a vault with a diameter of 70 to 80 cm (top furnace).
By David Shepardson. WASHINGTON (Reuters) -President-elect Donald Trump cannot ignore a law requiring Chinese-based ByteDance to divest its popular short video app TikTok in the U.S. by early next ...
Electric arc furnaces make steel from scrap or direct reduced iron. A "heat" (batch) of iron is loaded into the furnace, sometimes with a "hot heel" (molten steel from a previous heat). Gas burners may assist with the melt. As in BOS, fluxes are added to protect the vessel lining and help impurity removal.
