A support seat for improving the porosity of titanium sponge

Abstract

A support seat for improving the porosity of sponge titanium and titanium lumps, the support seat is used in a sponge titanium reduction distillation reactor, comprising an upper flange ring, a support cylinder and a lower flange ring each having a rough surface, the upper flange ring The inner edge of the ring is fixedly connected with the upper port of the support cylinder, the upper surface of the lower flange ring is fixedly connected with the end surface of the lower port of the support cylinder, and the side surface of the support cylinder is provided with a plurality of through holes. The invention can improve the force on the bottom of the titanium lump, thereby improving the porosity of the titanium lump, reducing the work difficulty for the downstream cutting and crushing of the titanium lump, and at the same time improving the smelting efficiency for the smelting of the finished sponge titanium.

Description

technical field [0001] The invention belongs to the technical field of non-ferrous metal smelting, in particular to a support seat for improving the porosity of titanium sponge in the production process of titanium sponge. Background technique [0002] At present, the domestic sponge titanium production furnace types are 5-ton furnace, 7.5-ton furnace, 10-ton furnace and other furnace types. The looseness of sponge titanium decreases with the increase of furnace tonnage, while most domestic sponge titanium smelting adopts vacuum consumable electrode arc. Furnace, smelting need to press the electrode of sponge titanium, and the porosity of sponge titanium equipment 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 interruption, which will bring great loss to the quality and smelting cost of titanium ingots. [0003] In t...

[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
