According to the different electrode electroslag furnace, divided into self and non self power consumption type furnace slag furnace two. The difference between the two is that the consumable electrode of the former is the melting material, and the melting process is continuously melting. The main lifting mechanism by electroslag furnace power supply and control system, mold or crucible, electrode, feeder, ingot and a water cooling system. When the first small smelting remelting of the alloy material and the required pieces of electro slag powder into a mold bottom, and then decreased in contact with the electrode alloy and arc furnace. Consumable electrode surface and electric arc furnace slag and the arc heating effect, quickly melted and formed a pool of molten metal and covered in the slag pool. With the melting and shortening of consumable electrode, the quantity of electric slag must be added regularly to get a certain depth of slag pool.
