Improved supporting ring type steel ladle slag detection sensor

Technical Field

The utility model relates to a sediment detection technology field under the ladle specifically is a sediment detection sensor under improved generation backing ring formula ladle.

Background

A continuous casting machine is a continuous casting apparatus for directly casting molten steel into a billet. In the continuous casting production process, an oxidant and impurities in molten steel are mixed to form liquid steel slag, and in the later casting period, a confluence cyclone accident is formed along with the reduction of the liquid level of molten steel in a steel ladle, and the steel slag can enter a tundish along a long nozzle along with the molten steel. After the steel slag flows into the tundish from the ladle, the purity of molten steel is influenced, a water gap of the tundish is blocked, continuous casting of multiple furnaces is influenced, the quality of steel billets can be influenced when the steel slag of the tundish enters the crystallizer, even, a leakage accident is caused, and the normal operation of continuous casting production is greatly influenced. The ladle slag-discharging detection device can detect the outflow conditions of molten steel and molten slag in the pouring process, sends out a control instruction to stop pouring after accurate judgment, effectively prevents the molten slag from flowing into a tundish, and is an important technology of non-oxidation pouring.

At present, be applied to external support ring formula ladle sediment detection device under steel mill (patent application number is 2021204486584), it has great advantage to adopt the sensor to pre-bury the sediment detection device under ladle brick cup exit to contrast the tradition, however, this detection device has some problems in the use more than a year, if: the sensor generates shell strain when used for a long time in a high-temperature environment, so that a welding part is cracked, and the outer ring is likely to fall off; when the sensor is used, the shell swings slightly by taking the pin shaft as an axis, but an operator can operate carelessly sometimes to cause the sensor to swing greatly, so that a lead-out cable is damaged; these factors affect the stability of the sensor's service life. Therefore, an improved trunnion ring type ladle slag tapping detection sensor is provided.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a sediment detection sensor under improved generation trunnion ring formula ladle possesses from structural improvement sensor preparation technology for sensor housing stress distribution is even, and the difficult advantage that ftractures of welding seam has solved the sensor and has used for a long time under high temperature environment and produce the casing and meet an emergency, makes the welding department fracture, leads to the problem that the outer loop drops.

In order to achieve the above object, the utility model provides a following technical scheme: an improved trunnion ring type steel ladle slag tapping detection sensor comprises a sensor shell with a circular ring column shape, wherein the lower part of the sensor is provided with a ring concave part, an electromagnetic coil is wound on the ring concave part, the outer side of the ring concave part is welded and sealed by two semicircular rings, the two semicircular rings are embedded into the ring concave part, and one semicircular ring is provided with a round hole for leading-out wires of the electromagnetic coil.

Preferably, the upper part of the sensor is provided with a mounting groove adapted to different long nozzles.

Preferably, the round hole is connected with an S-shaped round pipe, and the S-shaped round pipe is connected with a metal hose to achieve leading-out of the electromagnetic wire.

Preferably, a limit stop is arranged at the bottom of the sensor.

Compared with the prior art, the beneficial effects of the utility model are as follows:

the utility model discloses use the electromagnetic detection principle, be cyclic annular cover in the long mouth of a river outside of bale, can accomplish the sensor and detect the task, can also play the effect that supports and lift the long mouth of a river of bale simultaneously. The molten steel passes through the center of the trunnion ring type sensor, and the electric conductivity of the slag is lower than that of the molten steel under the condition of high temperature, so that the induced voltage in the slag is larger than that of the molten steel. The steel slag is mixed out at the later stage of casting steel, so that the conductivity of the solution is reduced, the electromagnetic field is enhanced, the output signal of the coil is changed along with the change of the slag content, and the corresponding slag content can be measured.
