The purpose of this technology is to provide a smelting system for zirconium lead - niobium alloy. In order to achieve the above objectives, this technology adopts the following technical scheme: a smelting system of zirconium niobium lead alloy, including the successively connected zirconium niobium lead electrode block processing device, vacuum filled argon welding box and vacuum self-consuming electric arc furnace. Preferably, the zirconium niobium lead electrode block processing device is a press machine, and the press machine is connected with the mixer, and the mixer is provided with a feed port, which is connected with the niobium chip processing device, sponge zirconium feed pipe and lead powder feed pipe respectively. Further preferably, the niobium chip processing device is a crushing machine. Further preferably, the grinder is connected with the electron beam furnace. Further preferably, the sponge zirconium feeding pipeline is connected with the sponge zirconium pretreatment device, which comprises a cleaning tank and a vacuum drying machine, and a sprinkler head with several spraying deionized water is arranged above the cleaning tank. (1) the niobium bar is processed into niobium chip, which is mixed with sponge zirconium and lead powder and then compressed into a number of electrodes of the same size, which are transferred to a vacuum tile-filled welding chamber, and transformed into consumable electrode by argon arc welding. (2) it can be obtained by smelting in vacuum consumable electric arc furnace; Among them, the mass ratio of sponge zirconium, niobium bar and lead powder is 5 ~ 8:1:0.
