Problems solved by technology
The quality of domestic electric melting furnaces is not high, which is not conducive to the improvement of production technology and product quality of white copper tubes for seawater desalination
The traditional point melting furnace has the same cross-sectional area up and down. The disadvantage of this point melting furnace is that due to the uneven distribution of the electric field, the temperature of each point inside the electric melting pool is quite different, and the raw material copper melting process is not uniform.
On the other hand, when the temperature of the furnace is too high, a large part of the internal heat is dissipated to the outside, which cannot be fully absorbed by the raw materials, wasting electric energy
In addition, in order to accurately and conveniently obtain the melting state of the molten material and the quality of the product, the current melting furnace also lacks the necessary facilities
Therefore, the existing melting furnace can no longer meet the current production needs

The invention discloses an electromagnetic stirring shield electric melting furnace which comprises an electric melting furnace shell. The electric melting furnace shell is divided into an inner electric melting furnace shell body and an outer electric melting furnace shell body. A heat shield layer is arranged between the inner shell body and the outer shell body. A heat insulation layer is arranged between the heat shield layer and the outer shell body. The upper portion of the electric melting furnace is a melting furnace and the lower portion of the electric melting furnace is a settling basin. The cross sectional area of the melting furnace is larger than that of the settling basin. A rotary magnetic field coil is arranged on the circumference of the settling basin. The settling basin is communicated with a holding furnace through a dog hole. The dog hole is provided with a sampling valve which is connected with a sample check meter. The electromagnetic stirring shield electric melting furnace has the advantages that electric energy loss of the electric melting furnace is reduced and product quality is improved.
Description
technical field [0001] The invention provides an electric melting furnace, in particular to an electromagnetic stirring shielding electric melting furnace. Background technique [0002] With the rapid development of my country's economy, the supply of fresh water and electricity will be in a long-term tense state. White copper tubes for seawater desalination are key materials for the development of seawater desalination, thermal power, nuclear power and ships. The electric melting furnace is a key facility for the raw material equipment used in the production of white copper pipes for seawater desalination. The function of the electric melting furnace is not only related to the consumption of electric energy, but also has an important impact on the quality of the copper pipes produced. The quality of domestic electric melting furnaces is not high, which is not conducive to the improvement of production technology and product quality of white copper tubes for seawater desalin...
