Abstract
A continuous casting crystallizer with automatic alarming and slag discharging functions is composed of a crystallizer body. A liquid level sensor is connected to the upper end of the crystallizer body and connected with a PLC through a signal line. The PLC is connected with a computer through a signal line. According to the continuous casting crystallizer with the automatic alarming and slag discharging functions, the amount of tundish slag entering the crystallizer can be reduced to a large extent, so that the casting blank yield is improved, and the casting blank quality is improved.
Description
Technical field
The utility model relates to a kind of continuous casting mold, specifically belongs to the continuous cast mold of slag under a kind of automatic alarm.
Background technology
In continuous casting production process, in the time of last stove of casting tundish, because the molten steel amount in tundish reduces gradually, water while binding soon to latter stage, often easily occur the phenomenon of slag mixed flow, the covering slag in tundish can enter crystallizer with molten steel.Instantly when slag is too much, strand afterbody binds and there will be roof fall phenomenon, causes the tail base bleed-out that binds, and affects continuous casting production direct motion.At present, enter crystallizer in order to control Tundish Slag, all take weigh and measure the method that remains molten steel amount with oxygen lance according to tundish.Take tundish to weigh and measure the method that remains molten steel amount with oxygen lance, the deficiency of its existence: it is to be undertaken by operating personnel's experience and range estimation, error is large, easily cause tundish casting surplus to increase, strand recovery rate reduces, and affects production cost, in addition, artificial judgment varies with each individual, and easily occurs that the situation that operate miss causes middle cinder inclusion to enter crystallizer occurs.
Utility model content
The purpose of this utility model is to overcome the deficiency that prior art exists, and a kind of problem that can significantly reduce Tundish Slag and enter crystallizer is provided, and makes strand recovery rate fall the continuous cast mold of slag under the automatic alarm of raising.
Realize the technical measures of above-mentioned purpose:
A continuous cast mold for slag under automatic alarm, is made up of crystallizer body, and it is: the upper end at crystallizer body is connected with liquid level sensor, and liquid level sensor is connected with PLC controller by holding wire, and PLC controller is connected with computer by holding wire.
Feature of the present utility model is: the problem that can significantly reduce Tundish Slag and enter crystallizer, makes strand recovery rate fall raising, and improve slab quality.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
In figure: 1-crystallizer body, 2-liquid level sensor, 3-holding wire, 4-PLC controller, 5-computer.
Detailed description of the invention
Be described further below in conjunction with accompanying drawing:
A continuous cast mold for slag under automatic alarm, is made up of crystallizer body 1, and it is at the upper end of crystallizer body 1 connecting fluid level sensor 2, and liquid level sensor 2 is connected with PLC controller 4 by holding wire 3, and PLC controller 4 is connected with computer 5 by holding wire 3.
Operation principle: when work, be arranged on the upper end connecting fluid level sensor 2 of crystallizer body 1 owing to generating an electromagnetic field, therefore molten steel and around conductor in produce eddy current, the distribution of electromagnetic field of eddy current depends on the height of molten steel liquid level in crystallizer body 1, this electromagnetic field can produce induced voltage and first be amplified by preamplifier in liquid level sensor 2, then be transferred to PLC controller 4 by holding wire 3, be transferred to computer 5 by PLC controller 4 again, do further processing via computer 5, convert liquid level signal to, liquid level signal is controlled the opening increase of stopper rod of tundish or slide plate by PLC controller 4 again or is reduced to realize the automatic control of mold liquid level.
In the time normally watering steel, molten steel in crystallizer body 1 is by the mold powder cover in crystallizer body 1, covering slag thickness is about 30mm left and right, the material that liquid level sensor 2 can detect is metal (molten steel in crystallizer body 1), and Tundish Slag is mineral composition, can not be detected by liquid level sensor 2, once but middle cinder inclusion enters in crystallizer body 1, owing to not having molten steel to supplement, therefore liquid steel level can start to decline along with middle cinder inclusion enters crystallizer body 1, this dropping signal can send warning by liquid level sensor 2, and automatically close stopper rod of tundish or slide plate and stop casting, normally bind.
This detailed description of the invention only exemplifies for the best, not the restricted enforcement to technical solutions of the utility model.
