Abstract
Description
The present invention relates to a melting furnace, and more particularly to an aluminum melting furnace.
Aluminum is a metal that is used as a high strength, high corrosion resistance alloy with various kinds of elements such as Si, Mg, Zn, Mn, Cu as well as being light and good processability, high electric and thermal conductivity. Accordingly, aluminum or an aluminum alloy is widely used in industries such as beverage cans, vehicles, household appliances, architecture, machinery, electricity, and aircraft.
Aluminum In the refining process to produce now, the dross (slag) floats on the surface of the molten metal. These drosses are removed to produce high purity aluminum now. In general, the dross on the surface of the molten metal not subjected to the flux treatment contains 80 to 90 wt% of aluminum, and 60 to 70 wt% of aluminum is contained in the dross on the surface of the molten metal subjected to the flux treatment for cleaning the molten metal . Since a large amount of aluminum is contained in the dross, efforts to recover aluminum or an aluminum alloy from the dross continue to be made.

According to one embodiment of the present invention, the damper includes a support plate for supporting the refractory, and the support plate is exposed to the atmosphere.
According to an aspect of the embodiment of the present invention, the damper includes a center weight connected to one side of the damper blade and a contact prevention wire for preventing the damper from contacting the inner surface of the duct at the maximum rotation.
According to the present invention as described above, the melting furnace body having a structure in which the charging inclined portion is located inside the shell portion of the main body can prevent the aluminum dross from coming into contact with the entire surface of the molten metal, It is easy to cool the lower portion of the furnace to suppress the thermal expansion of the lower portion of the furnace body to prevent cracking of the refractory and to prevent the erosion of the molten metal and further prevent the secondary accident caused by the leakage of the molten metal to the lower portion of the aluminum melting furnace have.
Further, the door part having the inclination angle of 5 degrees smaller than the door part having the inclination angle of 15 degrees in the prior art can easily install the door driving part or the auxiliary device for driving the door frame on the door top.
In addition, it has a natural cooling structure in which the support plate is exposed to the atmosphere in comparison with the conventional forced air-cooled damper, and has a simple structure that is easily accessible from the outside by being installed on a duct opened on one side. , The damper wing is lined with a refractory material, and the durability of the damper wing can be prolonged.
