The present invention relates to the Liquid Steel Level Control technology, particularly a kind of pick-up unit that sprays molten steel liquid level in the band bag.
Background technology
Existing molten steel liquid level detection technique has weight method, microwave method, isotope method and electric vortex method, wherein: weight method is because the spray band wraps in band process processed and will constantly adjust, can not meet the request for utilization of LOAD CELLS, weight method can only obtain a weight numerical value, and can not accurately obtain the liquid level information of molten steel; Microwave method adopts microwave to project liquid steel level, and reception echoed signal, by detection, launch with the mistiming of reflection wave and determine liquid level information, temperature difference for each point on hot environment and path on the path of microwave transfer causes unknown decay to microwave transfer speed, makes this method can't realize accurate measurement; The isotope method radiographic source is placed on the molten steel liquid level top, another ray receiver is placed on to the molten steel bottom, when ray penetrates molten steel, its intensity decays, draw liquid level, this method measuring accuracy is high, and amorphous spray band bag can not, in the molten steel bottom opening, determine that this kind method can not be used; Electric vortex method utilizes electromagnetic induction principle, utilizes the distance variation in direct ratio of electric heating difference and liquid steel level to obtain actual liquid level, and the spray band wraps in band process processed and needs heating, produces larger magnetic interference, and level gauging is also inaccurate.
At present, the level gauging of amorphous spray band bag is estimated the height change of float lever by operation is upper by human eye entirely, and Bao Xugang in manually adjusting, remain relatively stable, restricted a large amount of productions of domestic amorphous thin ribbon.
Summary of the invention
The objective of the invention is in order to solve above-mentioned problems of the prior art, provide that a kind of reliability is high, Operation and Maintenance simply, the detection method of the band of amorphous spray cheaply bag liquid level.
for achieving the above object, the invention provides a kind of pick-up unit that sprays molten steel liquid level in the band bag, this device comprises float 3, float lever 2, liquid level testing agency 1, PLC system 5, wherein: float lever 2 bottoms are arranged on float 3, the orienting sleeve on spray band bag 7 is passed at top, float 3 directly contacts the molten steel 8 in spray band bag 7, drive the liquid level of float lever 2 reflection molten steel 8, described liquid level testing agency 1 is provided with Fibre Optical Sensor 4, described Fibre Optical Sensor 4 is for detection of the change in displacement at float lever 2 tops, and testing result is fed back to PLC system 5, described PLC system 5 calculates the liquid level of current molten steel 8 according to testing result.
According to the present invention, can grasp accurately molten steel liquid level height in spray band bag, thereby can guarantee that the molten steel liquid level that sprays in the band bag is constant in real time to spraying continuous steel in the band bag, further control product quality, improve product stability, reduce production costs.

Embodiment
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
A kind of structure of the detecting device schematic diagram that sprays molten steel liquid level in the band bag that Fig. 1 provides for the embodiment of the present invention.As shown in Figure 1, this device comprises float 3, float lever 2, liquid level testing agency 1, PLC system 5, and wherein: float lever 2 bottoms are arranged on float 3, and the orienting sleeve on spray band bag 7 is passed at top; Float 3 directly contacts the molten steel 8 in spray band bag 7, drives the liquid level of float lever 2 reflection molten steel 8; In liquid level testing agency 1, be provided with Fibre Optical Sensor 4, this Fibre Optical Sensor 4 is connected with the PLC system, Fibre Optical Sensor 4 is through high temperature resistant design, can use under the rugged surroundings of spray band bag high ambient temperatures, be responsible for detecting the change in displacement at float lever 2 tops, and testing result (for example displacement signal) is fed back to PLC system 5, after PLC system 5 receives displacement signal, the displacement signal that receives is transformed, and the liquid level that obtains spraying the molten steel 8 in band bag 7 after it is calculated, simultaneously result of calculation is transferred to middle bag 9.Middle bag 9 determines whether in spray band bag 7, continue steel according to predefined level value.
Fibre Optical Sensor 4 in the embodiment of the present invention, it measures stroke is 190mm, heatproof 300 degree, the cable radius bend is 8mm, is of a size of M4*27mm (diameter 4mm* length 27mm).
Preferably, the PLC system is also supporting a touch-screen 6, and this touch-screen 6 is for showing in real time molten steel 8 liquid levels of current spray band bag 7.
Fig. 2 is the workflow schematic diagram of pick-up unit shown in Figure 1.As shown in Figure 2, the workflow of this pick-up unit is:
