Mould Oscillation and Deflection Detection Instrument

Mould Oscillation and Deflection Detection Instrument



Overview

The mold is a device that shapes the cast product in continuous steel
casting, and it is also the core equipment and key technology of continuous
casting machine. The main function of the mould oscillation deflection
detection instrument is to detect the the mould oscillation table’s
oscillation frequency, amplitude, deflection rate, phase, oscillation
trajectory curve, etc. Through the detection and adjustment of the detection
instrument, the mold moves along the outer arc of the continuous casting
machine according to the given amplitude, frequency and waveform deflection
characteristics.

The actual oscillation parameters of the mold oscillation table during the
operation and production process and the process parameters of the cast
products cannot be effectively known without the data detection of the mold
deflection detection instrument, so that the operator cannot adjust the
mould’s production process parameters in real time according to the real-
time situation of the on-site production.

The continuous casting mold deflection detection instrument independently
developed by our company is suitable for various molds such as slab, square
billet, round billet and shaped billet. The system obtains the process
parameters such as actual oscillation holographic parameters and negative
slip amount of the oscillation table by effectively detecting the movement
of the mold. The technicians can formulate the control strategy of the mould
according to these actual parameters, and improve the output and quality of
the product within a safe and reliable range.



The structure of the instrument

Continuous casting mold oscillation and deflection detection instrument is
mainly composed of sensor system, sensor signal conditioning circuit, power
supply circuit, synchronous data acquisition module, communication cable,
and software data analysis system.

There are three axial acceleration sensors installed in the mold oscillation
and deflection detection instrument, one of which is to detect the vertical
oscillation signal (Y axis), and the other two are to detect the horizontal
oscillation signal (X and Z axis). The signal obtained by the sensor is
processed by the preprocessor and the preprocessing module. The oscillation
signal and sensor status signal will be filtered and normalized, sent to the
synchronous data collector for digitization and feature extraction, and the
data is analyzed and processed by the master computer software to obtain
various oscillation parameters and process parameters required by users.

The features of the system

1. The actual oscillation state replaces the ideal oscillation state. The
actual oscillation state of the table is used to formulate a control
strategy, so that the oscillation table can be used to produce products with
more accurate oscillation.

2. Convenient detection method. The equipment can be used for on-site
inspection at any time, and the production site can grasp the operating
status of the on-site equipment in time, so that we can make production
adjustments to the equipment at any time.

3. Efficient working methods and processing platforms. The high-integration
equipment developed by embedded technology can work in high temperature and
harsh environment. This system can comprehensively detect XYZ three-axis

data operation and processing platform.

4. Powerful database function. The database adopts the mode of computer
automatic management and operator's manual assistance management, and there
are tables for recording historical data and alarm data and working
parameter setting table of monitoring system inside the database. By
adjusting the output range, the best output effect can be obtained.
