Description

Technical Field

[0001] The utility model relates to the field of smelting furnaces, in particular to a detachable vacuum induction smelting furnace. Background Art

[0002] In the prior art, vacuum induction melting furnaces are used to produce various alloy materials. Medium-frequency induction heating is used to perform high-temperature alloying on the raw alloy materials. This involves fastening a rammed crucible to an induction coil. The alloy melt is poured into a designated container by tipping the crucible, thereby producing a master alloy. This process is often performed under a vacuum or inert gas atmosphere. However, during the pouring process, this fastened crucible easily leaves residual solidified residue on the inner wall and at the pouring gate. This requires cleaning after each smelting operation, and even the slightest mistake may require the crucible to be rebuilt, increasing operating costs and reducing production efficiency. Furthermore, the prior art uses a single channel for filling the melting furnace with inert gas and lacks a precise device for detecting oxygen content within the furnace. This can lead to an insufficient inert gas atmosphere and oxidation of the molten alloy. Furthermore, the prior art lacks a stirring device or insufficient stirring during the alloy melting process, resulting in severe elemental segregation in the resulting alloy ingot and significantly reduced performance.

[0003] In summary, how to achieve sufficient stirring of the alloy melt during the heating process and facilitate the removal of the crucible containing the alloy melt has become an urgent problem that researchers in this field need to solve. Utility Model Content

[0007] During use of this solution, a crucible filled with the required smelting alloy materials (such as rods, particles, powders, etc.) is placed in the induction coil, and the furnace cover of the furnace body is tightly closed. Before heating the crucible, the second lifting rod rises to the limit position, and the crucible clamp is driven to move away from the top of the induction coil by the transverse movement module to avoid damage to the crucible clamp due to heat; when heating the crucible, the induction coil works, and during the heating process, the first lifting rod descends, and the vibrating rod is placed in the crucible to stir the alloy melt in the crucible so that the melt is stirred evenly to avoid serious segregation of elements in the alloy ingot after cooling; after heating is completed, the crucible clamp is moved to the top of the crucible through the transverse movement module, and the second lifting rod descends to clamp the crucible clamp, and the crucible is transported to the placement platform through the two-axis movement of lifting and transverse movement, so as to facilitate the removal of the crucible after cooling.

[0014] Pulling the pull rod causes the induction coil to drive the crucible to a tilted state. The molten alloy in the crucible flows out due to the tilt and flows into the mold on the casting mold stage, thereby directly pouring the heated molten alloy.

[0015] In order to ensure a high concentration of inert gas near the induction coil, the utility model adopts a method of providing a plurality of annular tubes arranged vertically and connected to the connecting tube on the inner wall of the furnace body; the induction coil is provided between the plurality of annular tubes, and an air outlet facing the induction coil is opened on the inner wall of the annular tube;

[0016] The inert gas enters from the inert gas inlet, passes through the annular tube, and is discharged from the gas outlet. The gas outlet angles on each annular tube are inconsistent and all face the inductive coil, thus achieving a higher inert gas concentration near the inductive coil.
