Description

(54) DEVICE FOR TREATMENT OF METAL MELT

The proposed device can have two versions.

FIG. 1 shows a schematic sectional view of a device with a device for fixing the chamber lid in height as a set of dimensional removable liners; in fig. 2 is a device with mechanisms for vertical movement of the lid, executed in the form of jacks.

Option 1 (see Fig. 1). The device has a lined chamber 1 and a lid 2 on which a mechanical agitator 3 is installed with a mixing body, made in the form of a blade 4. The mixer 3 is connected to a rotary drive (not shown) with the help of a hinge shaft 5, which can be changed with a length The camera 1 is interconnected with the lid 2 by means of vertical guides — three fasteners 7 fixed to the chamber shtang 6 and connected to the lid 7. covering each bar 6.

Three cylindrical segments 10 are fixed on the chamber, which are placed between the rods 6, covering the edges of the lid 2 and forming, together with the liners 9, a protective casing to prevent dust, gases and melt splashes in this part. Option 2 (see figure 2) o

The device is equipped with mechanisms for vertical movement of the cover, implemented in the form of jacks 11, which are both vertical guides and fixtures for fixing the cover in height. The jacks 11 are screwed and driven synchronously from the actuators (not shown in Fig. 2).

The device works as follows. Example. The operation of the device, as per variant 1, begins with the upper position of the cover 2. A part of the blade 4 of the agitator 3 is immersed in the melt. After srabatani part of the blade 4, immersed in the melt, the stirrer 3 is stopped, the cover 2 is connected to the lifting device G: and the drawing is not shown) and lift. Each rod 6 is removed one by one, jy 9 and the cover 2 is lowered with an agitator 3. The lower part of the blade 4 is lowered by the height of the liner 9. Then they turn on the drives of the agitator 3 and continue to work. After collecting the new part of the blade 4

in the manner described, the cover 2 with the blade 4 is again lowered. After the entire blade 4 has been worked off, the cover 2 is removed, the new blade 4 is fixed and the cover 2 is installed in the upper position.

Then the cycle of operation is repeated.

PRI mme R 2. The operation of the device, implemented in option 2, differs from the operation of the device, performed in option 1 only in that the vertical movement of the cover 2 for immersion

driven blades 4 into the melt carried out with the help of jacks 11.

The mixer 3 of the device can be made as a blade, and another type, for example rod.

Metal processing device

melt allows you to increase the duration of work of the mixing organ

to the required depth. This allows you to increase the operational reliability of the device and 2-3 times reduce the cost of its maintenance.

Claims (3)
