Detailed description of the invention
In order to improve the accuracy of alignment of described middle water containing opening and described crystallizer, the utility model provides a kind of centering device for tundish outlet, described device comprises: first pair of pointer, and one end of described first pair of pointer is connected with by ring, and described first pair of pointer is provided with handle; By ring, described one end by ring is connected with one end of second pair of pointer, and the other end of described second pair of pointer is connected with the first backup plate; The described other end by ring is connected with one end of the 3rd pair of pointer, and the other end of described 3rd pair of pointer is connected with the second backup plate; Wherein, by described first pair of pointer, described second pair of pointer, described 3rd pair of pointer, described centering device for tundish outlet is placed in the central point of described crystallizer, guarantees described middle water containing opening and described crystallizer precise alignment.
Below by drawings and the specific embodiments, the technical solution of the utility model is described in further detail.
The present embodiment provides a kind of centering device for tundish outlet, be applied on crystallizer, as shown in Figure 1, described device comprises: the first pair of pointer 11, by ring 12, handle 13, second pair of pointer 14, first backup plate 15, the 3rd pair of pointer 16, second backup plate 17; Wherein,
The mode that one end of described first pair of pointer 11 is fixed by welding or screw is connected with by ring 12, and described first pair of pointer 12 is provided with handle 13; Wherein, the mode that described handle 13 is fixed by welding or screw is arranged on described first pair of pointer 12.The length of described first pair of pointer 11 can be 650 ~ 1050mm.
Described mode of being fixed by welding or screw by one end of ring 12 is connected with one end of second pair of pointer 14, and the mode that the other end of described second pair of pointer 14 is fixed by welding or screw is connected with the first backup plate 15.
Described mode of being fixed by welding or screw by the other end of ring 12 is connected with one end of the 3rd pair of pointer 16, and the mode that the other end of described 3rd pair of pointer 16 is fixed by welding or screw is connected with the second backup plate 17.Wherein, described second pair of pointer 14 is identical with the specification of described 3rd pair of pointer 16, and described second pair of pointer 14 can be 48 ~ 49mm with the length of described 3rd pair of pointer 16.Described first backup plate 15 is identical with the specification of described second backup plate 17, and described first backup plate 15 is 1 ~ 2mm with the thickness of described second backup plate 17, and described first backup plate 15 is semicircle backup plate with described second backup plate 17.Vertical range between described first pair of pointer 11 and described first backup plate 15, described second backup plate 17 is 115mm.
Wherein, described first pair of pointer 11, described second pair of pointer 14, described 3rd pair of pointer 16, the described material by ring 12, described first backup plate 15 and described second backup plate 17 are metal material, and the material of described handle 13 is metal material or wooden; Described metal material can comprise stainless steel etc.
In practical application, before underway bag immersible ladle nozzle centering, the centering device for tundish outlet provided by the present embodiment is placed in crystallizer, makes first pair of pointer 11 point to the central point of narrow face copper plate of crystallizer, and namely first pair of pointer 11 and narrow face copper plate of crystallizer center line coincide; Make second pair of pointer 14 and the 3rd pair of pointer 16 point to Wide-surface copper plate of crystallizer central point, namely second pair of pointer 14 and the 3rd pair of pointer 16 and Wide-surface copper plate of crystallizer center line coincide simultaneously.Now, described centering device for tundish outlet is just in time precisely positioned at the central point of crystallizer.
By continuous casting production vehicle-mounted tundish reach the cast position of conticaster, described tundish immersed nozzle is made to be positioned at above crystallizer, the position of adjustment middle water containing opening, middle water containing opening is made to be sitting at the top of described centering device for tundish outlet, described tundish is steadily fallen into described centering device for tundish outlet, make the outer wall of middle bag soaking water gap and described centering device for tundish outlet by ring inwall good agreement, middle bag soaking water gap completes precise alignment.By handle 13, described centering device for tundish outlet is taken out.
Here, described mould wall thickness is 230mm, and narrow face copper plate of crystallizer is long is 230mm, and tundish immersed nozzle external diameter is 130mm..Because the diameter of the first backup plate 15 and the second backup plate 17 is 130mm, identical with tundish immersed nozzle external diameter; And second pair of pointer 14 length and the first backup plate 15 thickness sum are 50mm, 3rd pair of pointer 16 length and the second backup plate 17 thickness sum are 50mm, therefore namely can ensure that the spacing between the outer wall of described tundish immersed nozzle and two pieces of wide copper coins of crystallizer is identical.And the vertical range between first pair of pointer 11 and the first backup plate 15 and the second backup plate 17 is 115mm, therefore, can ensure that first pair of pointer can point to the mid point to narrow face copper plate of crystallizer.The center line solving tundish immersed nozzle and Wide-surface copper plate of crystallizer center line and narrow copper plate can not the technical problem of simultaneously centering.
The centering device for tundish outlet that the utility model provides, easy and simple to handle, accuracy of alignment is high, to solve in prior art artificial contraposition not problem accurately.And steel stream deflection in crystallizer can not be caused because of middle water containing opening skew, molten steel produces the phenomenon of bias current.Ensure that molten steel in mold even flow field, symmetry.Improve slab quality simultaneously, avoid bleed-out accident to occur, reduce production cost.
The above; be only preferred embodiment of the present utility model; be not intended to limit protection domain of the present utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
