Abstract
The utility model relates to an immersible ladle nozzle centering tool which comprises a centering staff gauge, a limit clamping beam and crystallizer limited blocks, wherein the centering staff gauge is arranged in the middle of the centering tool, the limit clamping beam is arranged on the top end of the centering staff gauge, the two ends of the centering staff gauge are provided with the crystallizer limited blocks, and the distance between the two crystallizer limited blocks is equal to the distance between the inner sides of two vertical faces of a crystallizer. The immersible water hole centering tool has simple structure, convenient use and operation, can accurately center a ladle nozzle and the crystallizer, effectively guarantees the quality of casting blanks, and improves the benefits of enterprises.
Description
Technical field
The utility model relates to a kind of adjustment instrument, particularly relates to a kind of submersed nozzle centering instrument.
Background technology
Submersed nozzle is the passage that the tundish molten steel flows into crystallizer, and the centering of submersed nozzle between crystallizer has very big influence for safety of watering steel and slab quality, therefore to the very strict requirement that is equipped with at the mouth of a river.The tundish submersed nozzle hole direction that spues is determined treating that the seat in the plane prepares, after the hired car centralising device is adjusted the position of the mouth of a river and crystallizer in cast position relies on, must guarantee that mouth of a river external diameter is to two wide identity distances of crystallizer, two leptoprosopy of hole direction over against crystallizer that spue from equal, the mouth of a river.At present, the centering of submersed nozzle when treating that the seat in the plane is prepared mainly adjusted by operator's range estimation, in hired car adjust in cast position the mouth of a river, back external diameter to two wide identity distances of crystallizer from equal, the hole direction is inclined to one side and the mouth of a river spues, can not be over against two leptoprosopy of crystallizer, because the collimation error, frequent appearance is the situation of centering accurately.Centering is inaccurate, and the middle back, cast position of hiring a car just can't be retrieved, and brings very big influence for the security and the slab quality of pouring molten steel.The centering that the cast mouth of a river, position and crystallizer are wide also is the range estimation by the operator, thereby there is certain error, though can adjust once more by middle hired car centralising device, but can not reach centering accurately, produce very big influence equally also for pouring practice and slab quality.
Summary of the invention
The utility model has overcome deficiency of the prior art, and a kind of simple in structure, easy to operate submersed nozzle centering instrument is provided.
In order to address the above problem, the utility model by the following technical solutions:
A kind of submersed nozzle centering instrument, comprise centering scale, spacing Ka Liang and crystallizer limited block, centering instrument middle part is provided with the centering scale, centering scale top is provided with spacing Ka Liang, centering scale two ends are provided with the crystallizer limited block, and the distance between two crystallizer limited blocks equals the distance between two facade inboards of crystallizer.
Compared with prior art, the beneficial effects of the utility model are:
By adopting the utility model centering instrument, the operator can realize accurately, fast that the mouth of a river the accurate centering for the treatment of seat in the plane and cast position, has guaranteed the quality of strand, has improved the performance of enterprises.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is treating seat in the plane centering schematic diagram for utilizing the utility model;
Fig. 3 is for utilizing the utility model at cast position centering schematic diagram.
The specific embodiment
A kind of submersed nozzle centering instrument, as shown in Figure 1, comprise centering scale 1, spacing card beam 2 and crystallizer limited block 3, centering instrument middle part is provided with centering scale 1, centering scale 1 top is provided with spacing card beam 2, centering scale 1 two ends are provided with distance between 3, two crystallizer limited blocks 3 of crystallizer limited block and equal distance between 8 two facade inboards of crystallizer.
Treat the centering at the mouth of a river, seat in the plane, as shown in Figure 2, the operator according to the central point of this instrument centering scale 1, can finely tune position, the mouth of a river when treating that the mouth of a river is prepared in the seat in the plane, realizes the accurate centering at the mouth of a river.Utilize mid point limited block 5 center lines of mouth of a river holder 7 and middle bag body 4 leptoprosopy center lines same vertical parallel lines, mid point limited block 5 center lines and the crystallizer 8 leptoprosopy center lines of mouth of a river holder 7 are foundation same vertical parallel lines during cast, the mid point limited block 5 of mouth of a river holder 7 as the spue datum mark of hole 6 centerings of the mouth of a river, spacing card beam 2 and 5 interlocks of middle water-coating port holder 7 mid point limited blocks with the centering instrument, by rotation mouth of a river angle, make the mouth of a river after the installation spue hole 6 center lines and mouth of a river holder 7 mid point limited block 5 center lines point-blank, so just make spue hole 6 vertical plane angles and middle bag body 4 vertical plane angles of the mouth of a river be consistent.
The centering at the mouth of a river, cast position, the centralising device of hiring a car in utilization fine setting position, the mouth of a river, the accurate centering of realizing 8 wide in the mouth of a river and crystallizer.As shown in Figure 3, when central hired car reaches crystallizer 8 tops, the utility model is inserted in the crystallizer 8, make 8 wide copper coins of crystallizer and 3 interlocks of crystallizer limited block, the central point that utilizes centering scale 1 is that crystallizer 8 leptoprosopy central points are foundation, by hired car leptoprosopy in adjusting to middle distance, make the mouth of a river spue the central point pointer of hole 6 center lines and centering scale 1, so just finish the mouth of a river spue hole 6 center lines and the check and correction of crystallizer 8 leptoprosopy center lines on same vertical parallel straight line at same position.
