Abstract

The invention discloses a vacuum arc remelting furnace. The vacuum arc remelting furnace comprises a movable burner and a static smelting station. The movable burner is connected with a driving support through a supporting mechanism. An electric conduction material rod penetrates through the center of the movable burner from top to bottom and is connected with the movable burner. The static smelting station comprises a copper crystallizer and a stainless steel water cooling jacket. The copper crystallizer is movably placed in the stainless steel water cooling jacket. The stainless steel water cooling jacket is fixed below the movable burner. A cable is twined around the outside surface of the stainless steel water cooling jacket. According to the vacuum arc remelting furnace, in the smelting process, electric currents pass through the cable twined around the outside surface of the stainless steel water cooling jacket of the static smelting station, thus a magnetic field is generated, and transverse force is exerted on metal smelted in a smelting cavity. Therefore, manual control over magnetic field stirring in the smelting cavity is achieved, the smelting precision is improved, and the available quantity of products is increased.

Description

technical field [0001] The invention relates to a vacuum melting furnace used in the field of metal melting. Background technique [0002] Vacuum arc remelting is a vacuum melting technology that uses an arc as a heat source to melt metals under vacuum conditions. [0003] Under the condition of no slag and vacuum, the metal electrode melts rapidly under the high temperature of the DC arc and resolidifies in the water-cooled copper crystallizer. When the liquid metal forms a droplet in the form of a thin layer and passes through the arc region of nearly 5000K to the crystallizer and is maintained and solidified in the crystallizer, a series of physical and chemical reactions occur to refine the metal and purify the metal. , Improving the crystal structure and improving performance. [0004] However, with such a vacuum melting technology, uncontrollable magnetic field stirring will be generated in the melting chamber during the melting process, and the crystals being melted...
