Technical Field

The invention belongs to the technical field of non-ferrous metal smelting, and particularly relates to a supporting seat for improving the porosity of titanium sponge lumps in a titanium sponge production process.

Background

At present, the domestic sponge titanium production furnaces are 5-ton furnaces, 7.5-ton furnaces, 10-ton furnaces and the like, the porosity of the sponge titanium is reduced along with the increase of the tonnage of the furnaces, most domestic sponge titanium smelting adopts a vacuum consumable electrode electric arc furnace, the sponge titanium is required to be pressed into an electrode during smelting, the porosity equipment of the sponge titanium influences the yield of the pressed electrode, if the porosity is poor, the electrode is interrupted or slag falls in the smelting process due to uneven particles, the smelting is abnormal or interrupted, and great loss is brought to the quality of a titanium ingot and the smelting cost.

In the process of producing titanium sponge in a reduction distillation reactor, the titanium lump on a sieve plate is compactly arranged at the bottom under the influence of high temperature and the self weight of the titanium lump, so that the looseness of the titanium lump is reduced, and adverse influence is generated on the cutting and crushing processes of the titanium lump.

Disclosure of Invention

The invention aims to provide a supporting seat for improving the looseness of titanium sponge lumps, which is supported on a sieve plate panel of a reduction distillation reactor, an upper flange ring at the upper part of the supporting seat supports the periphery of the titanium lumps, and the stress condition of the bottom of the titanium lumps is improved, so that the looseness of the titanium lumps is improved, the working difficulty is reduced for cutting and crushing the downstream of the titanium lumps, and the smelting efficiency is improved for smelting finished titanium sponge.

In order to achieve the purpose, the invention adopts the technical scheme that: the utility model provides an improve titanium sponge titanium lump looseness's supporting seat for in titanium sponge reduction distillation reactor, including last flange ring, a section of thick bamboo and the lower flange ring that all has rough surface, the inner edge of going up the flange ring with the last port fixed connection who props up a section of thick bamboo, the upper surface of lower flange ring with the terminal surface fixed connection who props up the lower port of a section of thick bamboo, prop up the side of a section of thick bamboo and seted up a plurality of through-holes.

And a plurality of upper rib plates are connected between the upper flange ring and the outer wall of the support cylinder.

The upper rib plates are uniformly arranged along the circumferential direction of the support cylinder.

And a plurality of lower rib plates are connected between the lower flange ring and the outer wall of the support cylinder.

The lower rib plates are uniformly arranged along the circumferential direction of the support cylinder.

The surface roughness of the upper flange ring, the support cylinder and the lower flange ring is less than 3.2 um.

The invention has the beneficial effects that: the titanium sponge lump titanium bottom support device can support the periphery of a titanium sponge lump titanium through the upper flange ring, so that the bottom stress of the titanium lump titanium is improved, the decrease of porosity caused by extrusion of the titanium lump on the sieve plate under pressure is avoided, and the bottom of the titanium lump titanium is tight and not beneficial to cutting. The through holes arranged around the support cylinder can ensure that the inside and the outside of the support cylinder are both in a liquid magnesium environment, and the growth of the titanium sponge is promoted. Go up flange ring, lower flange ring and a section of thick bamboo and form a central channel, be convenient for through the ejector pin from bottom to top push out titanium sticks together to the surface of going up flange ring, lower flange ring and a section of thick bamboo has certain roughness, can avoid titanium to stick together long on the supporting seat like this, also is favorable to sticking together titanium ejecting. The upper rib plate and the lower rib plate are arranged to avoid deformation of the flange ring and the support cylinder, so that the support seat can be repeatedly used.

The trial of the invention shows that the average barreled density of the titanium sponge of the 10-ton furnace is 1.45g/cm³The improvement is 1.32g/cm³And the barreled density is greatly improved.

Detailed Description

The present invention will be described in further detail with reference to the following drawings and examples, but the invention is not limited thereto.

Referring to the attached drawings, the supporting seat for improving the looseness of the titanium sponge lump comprises an annular upper flange ring 1, an annular lower flange ring 5 and a cylindrical supporting barrel 3, wherein an upper port and a lower port of the supporting barrel 3 are both open, the upper port of the supporting barrel 3 is welded with the inner edge of the upper flange ring 1, the end face of the lower port of the supporting barrel 3 is welded with the upper surface of the lower flange ring 5, in order to avoid deformation of the upper flange ring 1, the lower flange ring 5 and the supporting barrel 3 in use, the supporting seat is further provided with reinforcing rib plates, the supporting seat comprises an upper rib plate 2 arranged between the outer wall of the upper flange ring 1 and the outer wall of the supporting barrel 3 and a lower rib plate 4 arranged between the outer wall of the lower flange ring 5 and the outer wall of the supporting barrel 3, the upper rib plate 2 and the lower rib plate 4 are fixed in a welding mode, and the upper rib plate 2 and the lower rib plate 4 are uniformly arranged along the circumferential direction of the supporting barrel 3, so that the supporting seat can be repeatedly used for many times. The side equipartition of a section of thick bamboo 3 has a plurality of circular shape through-holes to make a section of thick bamboo 3 inside and outside through the through-hole intercommunication, make titanium in a section of thick bamboo 3 stick together for liquid magnesium environment all around, do benefit to the growth of titanium sponge.

Go up flange ring 1, lower flange ring 5 and a 3 surface of a section of thick bamboo have certain roughness to avoid titanium to stick together to grow on the supporting seat, as preferred, the roughness < 3.2 um.

When the upper flange ring 1 and the lower flange ring 5 are welded, the parallelism of the upper flange ring and the lower flange ring is ensured to be less than or equal to 2 mm.

All welded components of the present invention require full fillet welding.

The invention is tried by a titanium sponge company, and the average barreled density of 10 tons of furnace titanium sponge of the company is 1.45g/cm³The improvement is 1.32g/cm³The barreled density is greatly improved.
