[0036] As Figures 1-7As shown, a double-branch exchange electroslag furnace continuous production device comprises a base surface 1 and a remelting chamber 2, a control frame 3 installed on the base surface 1, two lifting branches 4 symmetrically connected to the control frame 3, two consumable electrodes 5 respectively arranged at the moving ends of the two lifting branches 4, an angle control assembly 6 arranged on the upper surface of the control frame 3, a translation assembly 7 fixed in the remelting chamber 2, a plurality of melting parts 8 arranged on the translation assembly 7, a plurality of cooling water conveying assemblies 9 respectively installed on the plurality of melting parts 8, a water inlet tank 10 fixed in the remelting chamber 2, and a water outlet tank 11 fixed on the water inlet tank 10;

[0037] The melting part 8 comprises a bottom water tank 12, a crystallizer 13 fixed on the bottom water tank 12 by bolts, and a plurality of support columns 14 fixed at the bottom of the bottom water tank 12, wherein

[0038] The two lifting branches 4 are adapted to control the two consumable electrodes 5 to alternately extend into one of the crystallizers 13 for work;

[0039] The angle control assembly 6 is adapted to synchronously adjust the angles of the two lifting branches 4 to control the two consumable electrodes 5 to alternately align with one of the crystallizers 13;

During work, the plurality of melting parts 8 containing remelted materials are hoisted into the translation assembly 7 in the remelting chamber 2, and one of the melting parts 8 is placed on the lower side in front of the control frame 3. Then, under the coordination of the two lifting branches 4 and the angle control assembly 6, the two consumable electrodes 5 can alternately complete the continuous processing and remelting work of a single electroslag ingot. After the electroslag melting in the melting part 8 is completed, the translation assembly 7 is operated to control the plurality of melting parts 8 to simultaneously adjust the positions, so that the melting part 8 where the electroslag melting is completed is separated from the control frame 3, and the remaining melting parts 8 containing unremelted materials are moved to the control frame 3, thereby realizing continuous remelting production work.
