Abstract
The utility model relates to a package liquid level automatic stabilization accurate control device in middle of the continuous casting, non-contact liquid level detector set up on the upper portion of middle package molten steel, and the middle package liquid level signal transmission that will detect gives the switch board, and rethread PLC programmable controller converts middle package liquid level signal to liquid level control signal, transmits for the servo valve through servo amplifier, and the pneumatic cylinder is connected to the servo valve. The utility model discloses a non-contact liquid level detector, accurate definite tundish liquid level height, at adjustment slag line in-process, through setting for can the accurate control tundish molten steel height, it is undulant in order to reduce the liquid level also can the accurate control tundish liquid level fluctuation simultaneously to can be with the control of tundish liquid level fluctuation range at 5 mm.
Description
Technical field
The utility model relates to a kind of continuous casting tundish leveling device.
Background technology
Traditional tundish level control mode, be according to molten steel weight in the tundish, adjust big jar of slide plate opening degree, to guarantee the tundish liquid level stabilizing, the precondition of this stable processing technique control tundish liquid level is: each tundish inclusion weight is basic identical, but because tundish access times difference, tundish weight changes, the inner molten steel height of tundish can not be accurately controlled thus, and molten steel face height in the tundish can not be adjusted.Take traditional tundish control stream mode to have hysteresis quality in addition, cause the tundish liquid level stabilizing poor, and the stable fluctuation with the tundish liquid level of mold liquid level have direct relation, because tundish liquid level instability, cause the mold liquid level instability, cause the slab quality instability thus.
By patent retrieval, present domestic tundish control stream mode is to take by weight mode to carry out the tundish level control, does not have alternate manner to carry out tundish and accurately controls stream.
The utility model content
The purpose of this utility model provides a kind of continuous casting tundish liquid level automatic stabilisation precise control device, by using the automatic precise and stable control device of tundish liquid level, can realize that the tundish liquid level controls automatically, and can adjust the tundish liquid level on request automatically.
For achieving the above object, the utility model adopts following technical scheme to realize:
Continuous casting tundish liquid level automatic stabilisation precise control device, it is characterized in that: this device is by contactless liquid surface detector, signal amplifies treating apparatus, the PLC Programmable Logic Controller, servo amplifier, servo valve, hydraulic cylinder, slide plate, Hydraulic Station is formed, contactless liquid surface detector is arranged on the top of tundish molten steel, amplifying treating apparatus with signal is connected, detected tundish liquid level signal is passed to switch board, convert tundish liquid level signal to the liquid level control signal by the PLC Programmable Logic Controller again, the liquid level control signal passes to servo valve by servo amplifier, servo valve connects hydraulic cylinder, the hydraulic cylinder power resources are in Hydraulic Station, and hydraulic cylinder is controlled the aperture of slide plate; Differential transformer connects hydraulic cylinder, is used for detecting the aperture of hydraulic cylinder, and this signal is passed to servo amplifier.
Described contactless liquid surface detector is meant eddy current testing instrument, ray type detector, laser detecting apparatus or supersonic reflectoscope.
The utility model is by contactless liquid surface detector, accurately determine the tundish liquid level, in adjusting the slag line process, can accurately control tundish molten steel height by setting, also can accurately control simultaneously the tundish liquid fluctuating with the minimizing liquid fluctuating, and tundish liquid fluctuating scope can be controlled at ± 5mm.
