The end face of the consumable electrode block pressed by the existing die is rectangular and has consistent specification, and then a single-layer electrode and a double-layer electrode are obtained by a 1 XN and 2 XN assembly welding mode. The single-layer electrode specification is smelting in a small crucible. The double-layer electrode is smelted in a large crucible. When the assembly welding is carried out, the welding angle is not easy to control due to the fact that the plane is too long, the arc is prone to burning the gun head and causing electrode oxidation, titanium melt is prone to flowing, welding seams are prone to rosin joint, the double-layer electrodes can only be welded on the punch and the bottom die face, the strength of the welding face is obviously insufficient, and certain quality and potential safety hazards exist during smelting.
Secondly, because the end face of the electrode block pressed by the existing mould is rectangular, on one hand, the filling rate of the electrode block put into a crucible is low, so that the optimal process of melting one ingot by one electrode cannot be implemented; on the other hand, the welding of the auxiliary electrode is influenced during primary smelting, the arc operation in the smelting is unstable, and the black shell and the thick flash on the surface of the primary ingot are difficult to perform flat-head treatment (the quality risk is large).
In addition, the existing mould can only press 2-3 specifications of electrode blocks, can not meet the requirements of medium-diameter crucibles, and is slightly influenced by the specification of the electrode, and the titanium alloy ingot for the structural part can only be changed from twice smelting to three times smelting; in addition, the size of the conventional electrode block is too large, the uniformity of components is poor, and the quality of a titanium alloy ingot is influenced.
