Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As shown in Figure 1, the utility model embodiment comprises ball float 2, pallet 3, positioning disk 4, mark post 5, scale 6, pointer 7.In order to the mechanism of clearer description the present embodiment, Fig. 1 also show the matching relationship of the present embodiment when applying and between tundish 11, and shows the molten steel 10 in tundish 11.
Specifically, ball float 2 is in spherical, surperficial for the molten steel 10 placing, swim in tundish 11.Preferably, ball float 2 is corundum or graphitic carbon fire resistive material, and for utilizing such material compressing by pressing process.Be connected in order to realize between ball float 2 with mark post 5 quick, ball float 2 is embedded with the steel loop arranging internal thread, and steel loop protrudes from ball float 2 surface, and the lower end of mark post 5 is threaded with steel loop.Further specifically, as shown in Figure 1, Figure 2, Figure 5, the top of ball float 2 is provided with a column 22, and namely steel loop is embedded in this column 22 in advance, or this column 22 is steel loop.That is the internal thread hole of column 22 core 21 is formed by the internal thread of this steel loop.In other examples, the middle part of column can be internal thread steel loop, and the outside material of column is the same with ball float material, is also fire resistive material, and outside and the ball float of column are integrally formed.Column can, when pouring basket liquid level fluctuates large, prevent molten steel from filling with in internal thread steel loop.
As shown in Figure 1, Figure 3, pallet 3 is in tabular, and preferred rounded tabular, it is for being laid on the clad 12 of tundish 11, and when practical application, the central area of clad 12 is provided with measures through hole 120, and namely pallet 3 is covered on this.The central area of pallet 3 is provided with the first through hole 30, first through hole 30 is corresponding with measurement through hole about 120, best axis is consistent, the diameter of the first through hole 30 and the diameter of measurement through hole 120 are all greater than the external diameter of ball float, can enter in middle handbag to make ball float through the first through hole 30 and measurement through hole 120.
As Figure 1 and Figure 4, positioning disk 4 is in tabular, preferred rounded platy structure, on its first through hole 30 stably covering pallet 3 and around the first through hole 30, and the central area of its positioning disk is provided with the second through hole 41, the diameter of the first through hole 30 is greater than the diameter of the second through hole 41, because the diameter of the second through hole 41 is mainly for moving up and down of mark post 5 provides guide effect, its diameter is slightly larger than the external diameter of mark post 5.
As shown in Figure 1, mark post 5, in shaft-like, is vertically arranged, and lower end is threaded with ball float 2 through after the second through hole 41, first through hole 30, third through-hole 120.
As shown in Figure 6, scale 6 is alongst provided with scale mark, vertically arranges, and parallel with mark post 5.Its lower end is fixed on pallet 3 also near mark post 5.
In order to the position of positioning disk 4 on simple and stable restriction pallet 3, as shown in the figure, pallet 3 upper surface is provided with annular protrusion 31, and positioning disk 4 embeds in annular protrusion 31, preferred orientation dish 4 embeds in the annular of annular protrusion 31 formation, and the outer wall of positioning disk 4 contacts with the inwall of annular protrusion 31.
In the present embodiment, pallet 3, positioning disk 4 are steel plate material.Further, the thickness of pallet 3 is greater than positioning disk 4.
In order to observe the position on mark post 5 top more accurately and in order to accuracy of reading, the present embodiment also comprises pointer 7, and it is horizontally disposed with, in arrow shaped, large end is fixed on the upper end of mark post 5, the most advanced and sophisticated surface pointed near scale 6 or point to scale 6.In order to reduce mark post 5, pointer 7 own wt to the pressure influence of ball float 2, improve precision, the mark post 5 of the present embodiment is steel pipe material, and pointer 7 structure in the form of sheets, can be made up of sheetmetal.
Each part dimension specification of the present embodiment should be determined according to specific needs, and such as in one embodiment, measurement through hole 120 diameter on tundish 11 clad 12 is 120mm; Pallet 3 is processed with upper steel plate by thickness 40mm, and the diameter of the first through hole 30 is 400mm; Positioning disk 4 is processed by the steel plate of thickness 20mm, and the diameter of the second through hole 41 is 150mm; Mark post 5 is processed by the steel pipe of diameter 18mm, thickness 5mm, lower end external threading; Pointer 7 utilizes sheet iron to shear; Scale 6 uses thickness 20mm steel plate to process, and width is 40mm, can also be other values, is of convenient length (being namely greater than the degree of depth of tundish and the thickness sum of clad); As for ball float 2, corundum, graphitic carbon fire resistive material can be used compressing, and diameter is approximately 100mm, compressing before in ball float pre-buried internal diameter 18mm internal thread steel loop.
Before using the present embodiment, time in tundish without molten steel, above the measurement through hole 120 pallet 3 centering being placed on tundish 11 clad 12, connect ball float 2 and mark post 5, ball float 2 is fallen in tundish 11 until contact with at the bottom of middle handbag by pallet 3 with mark post 5, positioning disk 3 falls in the location annular protrusion 31 of pallet 3 through mark post 5, scale 6 is fixed on pallet 3, pointer 7 along mark post axially lower slider be fixed on mark post 5, the adjustment position of pointer on mark post 5 makes 0 bit alignment of itself and scale, then fixed pointers.Inject in tundish molten steel or tundish outbound flow out molten steel time, ball float 2 swims on the molten steel 10 of tundish 11.
During measurement, ball float 2, along with the change of molten steel 10 liquid level, drives mark post 5 and pointer 7 upper and lower displacement, pointer 7 indicator scale 6, artificial visual inspection instruction numerical value, convenient grasp tundish 11 liquid level situation.
In other examples, when having molten steel in tundish, above the measurement through hole 120 pallet 3 centering being placed on tundish 11 clad 12, connect ball float 2 and mark post 5, fall into tundish 11 in until with middle handbag at the bottom of contact with mark post 5 by pallet 3 by ball float 2, positioning disk 3 falls in the location annular protrusion 31 of pallet 3 through mark post 5, and scale 6 is fixed on pallet 3, pointer is fixed on mark post 5 upper end, and now pointer pointed location on scale is altitude datum.Inject in tundish molten steel or tundish outbound flow out molten steel time, ball float 2 is along with the change of molten steel 10 liquid level, drive mark post 5 and pointer 7 upper and lower displacement, position on pointer 7 indicator scale 6 is measuring height, artificial macroscopic instruction numerical value deducts altitude datum and is pouring basket liquid level change in elevation, also conveniently can grasp tundish 11 liquid level situation.
To sum up, the utility model has multiple advantages, such as, realizes the monitoring constantly of pouring basket liquid level height, simple to operate, cost is low, safe and reliable.
As known by the technical knowledge, the utility model can be realized by other the embodiment not departing from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, is not only.Allly all to be included in the utility model within the scope of the utility model or being equal to the change in scope of the present utility model.
