Description

The invention relates to non-ferrous metallurgy, in particular to the production of sponge titanium by magnetothermic reduction of titanium tetrachloride.

A device is known, depicted in the book "Titan" by V. A. Garmat et al. M: Metallurgy, 1983, p. 372, Fig. 104, including a recovery apparatus with a lid, a drain device and a false bottom, consisting of a metal sheet on the supports. A solid metal sheet was attached to the wall of the recovery apparatus with three strips due to their welding to the wall.

The disadvantages of this device include the fact that the sheet was continuous and therefore the magnesium in the apparatus was not cleaned of impurities before the process itself. In addition, the products of electric welding, which fixed the plates to the wall of the apparatus, remained in it and could fall into titanium sponge. Therefore, the lack of purification of magnesium from impurities immediately before the process and the ingress of electric welding products in the apparatus during welding of the plates before each process significantly reduced the quality of sponge titanium.

The closest device to the claimed invention is a device for magnetothermal production of sponge titanium (prototype), described in RF patent No. 2238342 "Method for producing sponge titanium and a device for its implementation". The device for producing sponge titanium is made in the form of a recovery apparatus, consisting of a retort reactor with a cap and nozzles, a drain device, a false bottom, consisting of a perforated sheet with grooves mounted on supports, pressed from above by three step supports (holders).

The disadvantages of this device include the fact that a special device is required to install a perforated sheet under the upper supports (holders), while this requires increased labor costs and a longer installation. In addition, during the operation of the vacuum separation apparatus, when the perforated sheet is in an inverted retort capacitor, cases of falling of the sheet on the heat shield of the vacuum separation apparatus were observed, which led to the termination of the process and to the subsequent repetition of the process. All these disadvantages lead to a decrease in the performance of the device.

The technical result of the present invention is to improve the performance of the device.

The technical result is achieved in that in a device for producing sponge titanium, including a retort reactor with a cap and nozzles, a drain device, a false bottom made in the form of a perforated sheet with slots along the edges placed on the lower supports, it is new that the perforated sheet made along the edge with platforms formed by slots, the lower supports are made with holes for fixing the perforated sheet in a horizontal position on the lower supports using metal loops skipped through opening the lower supports and the platforms thrown over the perforated sheet.

- In addition, the sites formed by the slots are evenly spaced around the edge of the perforated sheet.

- In addition, the number of pads along the edge of the perforated sheet is at least four, located at an angle of 90 ° to each other.

The presence of metal loops located near the wall of the retort does not interfere with the installation of the perforated sheet on the lower supports. In this case, does not require a special device, which is used in the prototype to rotate the sheet (sheet weighing more than 100 kg), and bring it under the supports (holders). All these manipulations in the prototype increase the installation time, reduce the performance of the device.

In the case of the invention, metal loops are thrown onto the sites of the perforated sheet manually, which reduces the installation time and increases the productivity of the device.

When used for fastening a perforated sheet of metal hinges, the reliability of their fastening during the process is guaranteed.

And in the device of the known invention, it is possible to shift the sheet in the opposite direction and exit it from under the holders, if it is poorly brought under them. This significantly reduces the performance of the device, since it requires re-installation.

Therefore, all the features of the claimed invention provide a technical result.

A device for producing sponge titanium is shown in FIG. 1; FIG. 2 shows a perforated sheet.

The device consists of a retort reactor 1 with a cover 2 and nozzles 3, a drain device 4 and a false bottom 5, including a perforated sheet 6 with slots 7 forming platforms 8, which is mounted on the lower supports 9, to which are attached metal loops 10, passed through holes 11 in the supports 9. Thus, the perforated sheet 6 is attached to the lower supports 9 with metal loops 10 thrown over the platforms 8.

A device for producing sponge titanium works as follows.

Since the retort reactor 1 enters the reduction process with condensate of magnesium and its chloride after the vacuum separation process, the false bottom 5 is mounted in the retort condenser before the vacuum separation process. In four holes 11 of the supports 9 of the false bottom 5, metal loops 10, for example, of wire, are fixed and removed to the wall of the retort-condenser (retort-reactor 1).

Then, in the retort-condenser (retort-reactor 1), a perforated sheet 6 is placed on the supports 9, nothing interferes with its placement on the supports 9. On its four platforms 8, located at an angle of 90 °, metal loops 10 are manually thrown, introducing them through the slots 7 near the platforms 8, which significantly reduces the installation time and increases the productivity of the device. After mounting the false bottom, the retort condenser is checked for leaks and the vacuum separation apparatus is completely mounted. During the vacuum separation process, a condensate of magnesium and its chloride is deposited in the retort condenser. After the vacuum separation process is completed, the vacuum separation apparatus is cooled, dismantled, and the retort with magnesium condensate and its chloride is used as a retort reactor 1 in the reduction apparatus (device for producing sponge titanium). In the mounting stand, the retort reactor 1 is closed with a lid 2 with nozzles 3, the drain device 4 is welded to the retort reactor, the device is checked for leaks, installed in the recovery furnace, and the process for producing sponge titanium is carried out.

Thus, nothing prevents the placement of the perforated sheet on the supports 9, which reduces labor costs.

Manually stitching metal loops also reduces labor costs. Spontaneous removal of metal loops 10 from sites 8 during the processes of vacuum separation and recovery is excluded.

The acceleration of the installation time of the device and the exclusion of falling of the perforated sheet during the vacuum separation process increase the productivity of the invention.
