[0031] A method for preparing a zirconium vacuum consumable smelting electrode, characterized in that it comprises the following steps:
[0032] Step 1, cleaning the mold a11 and the mold b12, and connecting the round cake-shaped extrusion gasket 7 with protrusions distributed at one end to the extrusion rod 6;
[0033] Step 2, placing a plug matching it in the mold b12;
[0034] Step 3: Weigh 100-180kg of the zirconium sponge raw material, and slowly pour it into the mold a11 cleaned in step 1, wherein the zirconium sponge raw material has a particle size of 0.83-25.4mm and a density of 2.2-2.7g / cm 3 ;
[0035] Step 4, under the action of the slider 9 and the mold base 8, the extrusion gasket 7 in the step 1 is in contact with the sponge zirconium raw material in the step 3, and stops when it is completely extruded into the mold b12, and the extrusion Gasket 7 is separated from the zirconium sponge raw material;
[0036] Step 5, slowly pour the sponge zirconium raw materia...
Embodiment 1
[0039] The raw materials are selected with a particle size of 0.83-25.4mm and a density of 2.3g / cm 3 zirconium sponge
[0040] The inner diameters of the through hole 1 and the discharge guide cylinder 3 are both 450mm.
[0041] Clean up mold a11 and mold b12, and connect the round cake-shaped extrusion gasket 7 with protrusions on one end to the extrusion rod 6; place a plug that matches it in mold b12, weigh 100 kg of sponge zirconium raw material, and slowly Pour into the cleaned mold a11; under the action of the slider 9 and the mold base 8, the extrusion gasket 7 is in contact with the sponge zirconium raw material, and stops when it is completely squeezed into the mold b12, and the extrusion gasket 7 Separate from the sponge zirconium raw material; repeat the filling 20 times, replace the extrusion gasket 7 with a round cake-shaped extrusion gasket 7, place the plug in the mold b12 to continue extrusion, and pass through the through hole 1 and the discharge guide cylind...
Embodiment 2
[0044] The raw material is zirconium sponge with a particle size of 0.83-25.4mm and a density of 2.3g / cm.
[0045] The inner diameters of the through hole 1 and the discharge guide cylinder 3 are both 550mm.
[0046]Clean up the mold a11 and mold b12, and connect the round cake-shaped extrusion gasket 7 with protrusions on one end to the extrusion rod 6; place a plug that matches it in the mold b12, weigh 150 kg of the sponge zirconium raw material, and slowly Pour into the cleaned mold a11; under the action of the slider 9 and the mold base 8, the extrusion gasket 7 is in contact with the sponge zirconium raw material, and stops when it is completely squeezed into the mold b12, and the extrusion gasket 7 Separate from the sponge zirconium raw material; repeat the filling 40 times, replace the extrusion gasket 7 with a round cake-shaped extrusion gasket 7, place the plug in the mold b12 to continue extrusion, and pass through the through hole 1 and the discharge guide cylinder...
