Embodiment Construction
[0012] A titanium sponge supporting and pore-forming device for producing titanium lumps, the present invention will be further described in detail below with reference to the accompanying drawings.
[0013] like figure 1 As shown in the figure, a titanium sponge producing titanium lump support and hole forming device is mainly extended into the sieve plate center hole 5 provided on the sieve plate 6 by the bottom end of the support cylinder 1; the upper part of the support cylinder 1 and the Bolt holes 4 are provided in the middle and lower parts of the conical head 2; after the bottom end of the conical head 2 extends into the interior of the top end of the support cylinder 1, the conical head 2 and the support cylinder 1 pass through the bolt 3 into the bolt hole 4 to carry out the process. Fixed connection.

A supporting and pore-forming device for producing a titanium lump from titanium sponge is mainly characterized in that the bottom end of a supporting barrel extends into a sieve plate center hole formed in a sieve plate, a conical head is arranged at the top of the supporting barrel, and the supporting barrel and the conical head are connected through bolts. Before reduction feeding production, the device is hung into a reactor for reduction production, after reduction is finished, the height of a titanium lump is larger than that of the device, the device enters the earlier stage of distillation, the supporting barrel of the device plays a role in supporting the upper portion of the titanium lump, and the acting force of the upper portion of the titanium lump on the lower portion of the titanium lump is reduced. In the later stage of distillation, under the action of high-temperature sintering and gravity, the height of the titanium lump is shortened, the conical head penetrates through the upper portion of the titanium lump, a hole is formed in the center of the titanium lump, and distillation vacuum can reach the center of the titanium lump in time. By utilizing the device, the supporting effect on the upper titanium lump in the earlier stage of distillation and the pore-forming effect on the titanium lump in the later stage of distillation are realized, the structural compactness of the sponge titanium lump is improved, and the production power consumption cost is saved.
Description
technical field [0001] The invention relates to production equipment of sponge titanium, in particular to a support and pore-forming device for producing titanium lumps from sponge titanium. Background technique [0002] The large-scale production of titanium sponge production furnace is the development trend. After the large-scale furnace type, the diameter and length of the titanium lump will become larger, and the output of titanium sponge in a single furnace will increase, which can greatly improve product quality, save consumption and labor costs. In the industrial production of titanium sponge, magnesium is used to reduce titanium tetrachloride to produce titanium sponge. During reduction production, the temperature of the reaction point is above 1200 ° C, after the reduction and feeding of titanium sponge is completed. When the height enters the 1000 ℃ high vacuum distillation to remove magnesium and magnesium chloride, due to the high height of the titanium lump, the...
