Abstract
Description
TECHNICAL FIELD
[0001] The present disclosure relates to the technical field of water atomization powder production, and particularly relates to a centering device for tiling a tundish. BACKGROUND
[0002] The water atomization method uses high-pressure water as a breaking and cooling medium to produce powder through an atomization device. The molten steel liquid is formed into a stable downward columnar metal liquid stream after being controlled by the nozzle of the tundish of the atomization device, and the metal liquid stream is broken into small metal liquid droplets by the high-speed water flow from the atomization nozzle and is rapidly condensed into solid powder particles. The tundish of the water atomization method atomization device is tiled by manual operation. In the tiling process, the operator installs the tundish shell, the lining brick layer and the nozzle one by one, and then adds fine particle magnesia dry vibrating material into the cavity between the lining brick layer and the shell, and then vibrates and compacts the dry vibrating material by a vibrator.
[0003] The vibrator vibrates and compacts the dry vibrating material from the top of the tundish. In the process of vibration and ramming, due to the uneven filling of the dry vibrating material in the cavity between the lining brick layer and the shell, when the outer wall of the lining brick layer is extruded by the dry vibrating material, the nozzle and the lining brick are prone to non-directional misalignment and deviation, so that the nozzle and the lining brick layer deviate from the center of the outlet of the tundish, thereby affecting the flow direction of the metal liquid stream at the outlet of the tundish, causing the metal liquid stream to deviate, and further causing the tundish to be blocked and the high-pressure water to be sprayed back.

[0027] like Figure 1 As shown, the structure of the existing masonry intermediate tundish 20 includes an outer shell 20a, a dry vibratory material layer 20b, an inner brick lining layer 20c, and a funnel 20d. The inner brick lining layer 20c is built inside the outer shell 20a, and a funnel-shaped inner cavity is formed at the bottom of the inner brick lining layer 20c. The funnel 20d is embedded in the outlet part at the bottom of the inner brick lining layer 20c. Fine granular dry vibratory material is filled between the outer shell 20a and the inner brick lining layer 20c to form the dry vibratory material layer 20b. In the existing tundish 20 construction process, during the stacking operation, the vibrator compacts the dry vibrating material below from the top of the tundish 20. During the vibration and compaction process, due to the uneven filling of the dry vibrating material in the cavity between the inner lining brick layer 20c and the outer shell 20a, when the outer wall of the inner lining brick layer 20c is squeezed by the dry vibrating material, the nozzle 20d and the inner lining brick are prone to non-directional misalignment and displacement. This causes the nozzle 20d and the inner lining brick layer 20c to deviate from the outlet center of the tundish 20, thereby affecting the flow direction of the molten metal at the outlet of the tundish 20, resulting in the molten metal flow deviation, and consequently causing problems such as tundish clogging and high-pressure water backflow.

[0033] As shown in Figure 3 and Figure 4 As shown, in one of the embodiments, the centering device 10 for building the tundish further includes a locking block 400, one end of the locking block 400 is provided with a threaded groove 401, the movable adjustment portion 210 is threadedly connected to the threaded groove 401, and the locking block 400 abuts against one end of the symmetric adjustment block 300 away from the bottom plate 100. In the embodiment, when the symmetric adjustment block 300 abuts against the inner wall of the inner lining brick layer 20c of the built tundish 20, since the dry vibrating material is filled between the outer shell 20a of the tundish 20 and the inner lining brick layer 20c, and the dry vibrating material is tamped and compacted by the vibrator, the inner lining brick layer 20c is continuously impacted by the vibration to cause the symmetric adjustment block 300 to slightly vibrate and displace, so that a gap is generated between the symmetric adjustment block 300 and the inner wall of the inner lining brick layer 20c of the tundish 20, and the inner lining brick layer 20c is slightly deviated; the one end of the symmetric adjustment block 300 away from the bottom plate 100 is abutted by the locking block 400, so that the symmetric adjustment block 300 is locked and fixed, thereby preventing the gap between the symmetric adjustment block 300 and the inner wall of the inner lining brick layer 20c of the tundish 20, and further making the fixing effect of the inner wall of the inner lining brick layer 20c of the tundish 20 better, and preventing the inner lining brick layer 20c from being dislocated and deviated.

[0036] As shown in the drawings, Figure 4 As shown in the drawings, in one embodiment, the bottom plate 100 is provided with a mounting hole 101, the mounting hole 101 is located at the center of the positioning ring 110, and the height adjusting rod 200 is provided with a threaded connecting portion 220 at the end away from the movable adjusting portion 210, and the threaded connecting portion 220 is threadedly connected to the mounting hole 101.
