Supporting seat for improving looseness of titanium lump of titanium sponge

Abstract

A supporting seat for improving the looseness of a titanium lump of titanium sponge is used in a titanium sponge reduction distillation reactor and comprises an upper flange ring, a supporting cylinder and a lower flange ring which are all provided with rough surfaces, the inner edge of the upper flange ring is fixedly connected with an upper end opening of the supporting cylinder, the upper surface of the lower flange ring is fixedly connected with the end face of a lower end opening of the supporting cylinder, and a plurality of through holes are formed in the side face of the supporting cylinder. The bottom stress condition of the titanium lump can be improved, so that the looseness of the titanium lump is improved, the working difficulty of downstream cutting and crushing of the titanium lump is reduced, and meanwhile, the smelting efficiency of finished titanium sponge is improved.

Description

technical field [0001] The invention belongs to the technical field of non-ferrous metal smelting, and in particular relates to a support seat for improving the porosity of sponge titanium in the production process of sponge titanium. Background technique [0002] At present, domestic sponge titanium production furnace types are 5-ton furnace, 7.5-ton furnace, 10-ton furnace and other furnace types. The porosity of sponge titanium decreases with the increase of furnace tonnage, while most domestic sponge titanium smelting adopts vacuum consumable electrode arc Furnace, smelting needs to press the titanium sponge into the electrode, and the porosity of the titanium sponge affects the yield of the piezoelectric electrode. If the porosity is poor, the uneven particles will cause the electrode to break or drop slag during the smelting process, resulting in abnormal smelting Or interrupt, bring great loss to the quality of titanium ingot and smelting cost. [0003] In the proces...

[0002] At present, domestic sponge titanium production furnace types are 5-ton furnace, 7.5-ton furnace, 10-ton furnace and other furnace types. The porosity of sponge titanium decreases with the increase of furnace tonnage, while most domestic sponge titanium smelting adopts vacuum consumable electrode arc Furnace, smelting needs to press the titanium sponge into the electrode, and the porosity of the titanium sponge affects the yield of the piezoelectric electrode. If the porosity is poor, the uneven particles will cause the electrode to break or drop slag during the smelting process, resulting in abnormal smelting Or interrupt, bring great loss to the quality of titanium ingot and smelting cost

[0003] In the process of producing sponge titanium in the reduction distillation reactor, under the influence of high temperature and the weight of the titanium lump, the bottom of the titanium lump on the sieve plate is dense, thereby reducing the porosity of the titanium lump, and the cutting and crushing of the titanium lump adverse effect on the process
