Vibrating ladle slag carry-over detection-oriented embedded data acquisition system

Abstract

The invention discloses a vibrating ladle slag carry-over detection-oriented embedded data acquisition system. The system comprises a multi-point parallel signal acquisition system, a signal pre-processing system and a real-time data analysis system, wherein the multi-point parallel signal acquisition system determines a plurality of characteristic vibration signal measurement points by taking a ladle pouring mechanism and a supporting rack thereof as examination objects; a vibration sensor is arranged at each measurement point to acquire an impact vibration signal generated during the ladle pouring in all directions; the signals are primarily amplified and finally transmitted to the signal pre-processing system in a parallel mode; the signal pre-processing system can receive real-time vibration signals of a plurality of paths of the sensors, pre-process the signals and upload the signals to the real-time data analysis system; and the real-time data analysis system receives a real-time data packet uploaded by the signal pre-processing system, splits the data packet according to data transmission protocol format convention, extracts the impact vibration signal of steel steam and performs the functions of display, storage and analytical judgment.

Description

technical field [0001] The invention relates to the field of iron and steel metallurgical process detection and control, in particular to an embedded data acquisition system for slag detection of a vibrating ladle. Background technique [0002] In the process of continuous casting of iron and steel, the oxidant and impurities in molten steel are mixed to form liquid steel slag, which has a light specific gravity and floats on the upper part of molten steel. In the later stage of ladle pouring, steel slag gradually flows into the tundish from the ladle, and gradually accumulates in the tundish, which affects the quality of steel, and even makes continuous casting impossible in severe cases. With the continuous expansion and development of modern industrial production, the requirements for the variety and quality of steel continue to increase. Of course, the requirements for the purity of molten steel in continuous casting production are also getting higher and higher. Contin...
