Slab continuous casting bleed-out early warning system

Abstract

The invention provides a slab continuous casting bleed-out early warning system, and relates to the technical field of microwave detection. The slab continuous casting bleed-out early warning system comprises a microwave detection device, a signal conversion device, a control device, a driving device and an alarm device, wherein the control device controls the driving device in a slab outlet roller way to rotate so as to enable a billet shell in a crystallizer to move relative to the microwave detection device; the microwave detection device is used for sensing the thicknesses of a plurality of positions of the billet shell in the crystallizer so as to correspondingly generate a plurality of microwave signals; the signal conversion device correspondingly generates a plurality of voltage signals according to the plurality of microwave signals; the control device controls the alarm device to send out an alarm signal when the amplitudes of all the voltage signals do not meet a preset condition. Therefore, the slab continuous casting bleed-out early warning system can solve the problem that the existing slab continuous casting bleed-out early warning system gives a false alarm or has alarm failure due to adoption of a thermocouple.

Description

technical field [0001] The invention relates to the technical field of microwave detection, in particular to a slab continuous casting breakout early warning system. Background technique [0002] With the continuous development of industry, steel is widely used in various industries. However, in the process of iron and steel processing, there will generally be a problem of steel breakout. Because the problem of steel breakout will not only affect the efficiency of steel processing, but also cause serious casualties. Therefore, the early warning technology of steel breakout is receiving more and more attention. Much attention. In the existing steel breakout early warning technology, the temperature information of the billet shell in the crystallizer is generally collected by thermocouples to judge whether there is a risk of steel breakout, so as to realize the early warning function. [0003] The inventor found that the existing slab continuous casting breakout early warnin...

Problems solved by technology

[0004] In view of this, the object of the present invention is to provide a slab continuous casting breakout early warning system to solve the problem that the existing slab continuous casting breakout early warning system has unstable thermoelectric characteristics due to the quality problem of the thermocouple itself and Due to the wrong assembly method of the thermocouple or poor sealing effect, the deviation between the measured temperature and the actual temperature after water inlet is too large, so as to solve the problems of false alarm or leakage alarm
