Abstract

The invention relates to a low-cost niobium-titanium alloy electrode preparation method and a niobium-titanium alloy electrode. The niobium-titanium alloy electrode preparation method comprises the steps of material distribution, electrode block pressing, electrode assemble welding and electrode smelting. According to the low-cost niobium-titanium alloy electrode preparation method, compared witha traditional niobium-titanium alloy electrode preparation method, the raw material cost is low, the manufacturing cost is low, and the yield is high; by using the method, the length of an electrode block joint welding seam can be increased, the strength of the electrode is improved, the problem of niobium inclusion caused by block falling of a core during smelting of the niobium-titanium electrode prepared by the common titanium and titanium alloy electrode preparation method can be solved, and a cast ingot obtained after smelting of the prepared electrode is free of niobium inclusion.

Description

technical field [0001] The invention relates to the technical field of electrode preparation, in particular to a method for preparing a low-cost niobium-titanium alloy electrode and the niobium-titanium alloy electrode. Background technique [0002] Titanium and titanium alloys usually press the electrode block first, and then assemble and weld the electrode and then smelt it. If this method is used for the niobium-titanium binary alloy, when it is smelted to the joint of the electrode block, it is easy to lose the block because the titanium melts first, and the high melting point niobium The niobium-containing inclusions are not fully melted in the molten pool, and the niobium content in the dropped block is low and the niobium is easy to agglomerate to form a large niobium non-melting block. Even during remelting, since the melting point of niobium-titanium alloy is much lower than that of niobium, the large niobium infusible blocks formed by agglomeration are difficult to...
