Abstract
The utility model relates to a conticaster molten steel level gauge instrument maintains the field, in particular to molten steel level gauge off-line check device, a serial communication port, including support, check groove, check plate and elevating gear, open-top's check groove sets up on the support, and the check plate suspends in midair at the check groove through elevating gear. The lifting device comprises a support frame, a screw rod and a nut, a crank is arranged on the nut, a sliding groove is formed in the surface of the screw rod along the axis, and a protrusion matched with the sliding groove is formed in the support frame. Compared with the prior art, the beneficial effects of the utility model are that: the measurement deviation of the molten steel hydraulic gauge can be tested and corrected again in an off-line state, so that the stability of the molten steel level gauge instrument is improved, the failure rate is reduced, the maintenance period of the crystallizer is prolonged, and the workload of maintenance personnel is reduced.
Description
Technical field
The utility model relates to conticaster liquid steel level meter instrument area of maintenance, particularly a kind of liquid steel level meter off-line verifying unit.
Background technology
In the continuous casting production working procedure of steel mill, Mold Steel Level is controlled in continuous casting production and plays vital effect, it is the core that continuous casting is produced, Mold Steel Level is controlled and is not only directly had influence on the quality of steel billet, and the control of mold liquid level also has influence on poring rate, then have influence on the output of continuous casting.
The detection of molten steel in mold liquid level and the requirement of automatically controlling are very strict.For guaranteeing production direct motion, in regular maintenance, need regularly with checking table, in crystallizer, to proofread, guarantee that the measurement of liquid steel level meter is accurate.But in actual production process, often there are many emergency case that for example cable bad of liquid steel level meter occurs, level detection fluctuation increases etc., need online check and correction liquid steel level meter, confirm the accurate of measurement, but now in crystallizer, there is molten steel cannot realize online check and correction, if liquid level misalignment seriously will cause casting machine casting speed, reduce and affect output.During normal production, in crystallizer, be full of molten steel, verifying work is only limited to periodical repair or waters for a long time minor tick and just can carry out, and when measured deviation appears in liquid level, can only wait until periodical repair or water for a long time minor tick and proofread, because gap periods is long, cannot guarantee the stable performance of liquid steel level meter instrument.
Summary of the invention
The purpose of this utility model is to provide a kind of liquid steel level meter off-line verifying unit, can be under the state of off-line the measured deviation of verification molten steel hydraulic ga(u)ge, improve the stability of liquid steel level meter instrument, when reducing fault rate, extend maintenance period, minimizing attendant's workload.
For achieving the above object, the utility model adopts following technical scheme to realize:
Liquid steel level meter off-line verifying unit, comprises support, verification groove, verifying plate and lowering or hoisting gear, and open-topped verification groove is arranged on support, and a side of verification groove is provided with probe placement supporting plate, and verifying plate is suspended in verification groove by lowering or hoisting gear.
Described lowering or hoisting gear comprises support, screw rod and nut, and nut is provided with crank, and the surface of screw rod is provided with chute along axis, and support is provided with the projection of mating with chute.
Compared with prior art, the beneficial effects of the utility model are: can under the state of off-line, the measured deviation of tested steel water hydraulic meter also again revise, thereby be conducive to improve the stability of liquid steel level meter instrument, reduce fault rate, extend crystallizer maintenance period, minimizing attendant's workload.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further:
See Fig. 1, Fig. 2, it is the utility model liquid steel level meter off-line verifying unit example structure schematic diagram, comprise support 1, verification groove 2, verifying plate 3 and lowering or hoisting gear 4, open-topped verification groove 2 is arranged on support 1, one side of verification groove 2 is provided with probe placement supporting plate 12, and verifying plate 3 is suspended in verification groove 2 by lowering or hoisting gear 4.Lowering or hoisting gear 4 comprises support 5, screw rod 6 and nut 7, and nut 7 is provided with crank 8, rotates crank 8, nut 7 rotates relative to support 5, and the surface of screw rod 7 is provided with chute 9 along axis, and support 5 is provided with the projection 10 of mating with chute, while preventing from shaking crank, screw rod is followed nut rotation.
During verification, the stock of liquid level meter probe 11 is placed on probe placement supporting plate 11, verification groove 2 is used for simulating crystallizer, probe placement supporting plate 12 is used for simulating crystallizer cover plate, liquid level meter probe 11 is visited to the top of verifying plate 3, just can be carried out at any time off-line and proofread, its concrete operations are as follows:
1) with the actual liquid steel level of verifying plate 3 simulation, shake crank 8 and make verifying plate 3 increase until pop one's head in 11 apart from being 0mm with liquid level meter, be demarcated as zero point herein;
2) by shaking crank 8, verifying plate 3 is dropped to liquid level meter probe 11 apart from 100mm place again, now do OPC calibration, and corresponding with display list;
3) by shaking crank 8, regulate verifying plate 3 height again, the liquid level that contrasts respectively 0mm, 30mm, 60mm, 90mm, 120mm place shows, the stability of liquid level meter probe 11 is proofreaded.
