Description

Portable continuous casting crystallizer vibration monitoring device

Technical Field

The utility model belongs to the field of continuous casting equipment, relates to a crystallizer vibration detection system in continuous casting equipment, and particularly relates to a portable crystallizer vibration monitoring device.

Background

The mold is a water-cooled copper pipe and an auxiliary for receiving molten steel and solidifying the molten steel into a cast slab according to a predetermined cross-sectional shape, and is an important component of a continuous casting machine. The crystallizer is driven to vibrate by mechanical, hydraulic, electrohydraulic, electric and other vibration devices. The vibration of the crystallizer has the effects of preventing the casting blank from being bonded with the copper wall of the crystallizer in the solidification process, reducing the blank drawing resistance and improving the surface quality of the casting blank. If the vibration effect does not reach the standard, defects may be generated on the surface of the casting blank and the performance of the finally rolled steel product is affected, and even steel leakage accidents may be caused when the vibration effect is serious. Therefore, a crystallizer vibration monitoring device needs to be developed, accurate monitoring and analysis of the vibration state of the crystallizer are realized, and reliable guidance is provided for continuous casting production operation maintenance.

There are many products for monitoring vibration of a crystallizer in the market, for example, the utility model patent with publication number CN204649304U discloses a portable vibration detection system for a crystallizer. The system consists of a portable industrial personal computer and a portable sensor box. The portable sensor box is internally provided with a triaxial acceleration sensor which can collect vibration data, the portable sensor box transmits the sensor data to the portable industrial personal computer in a wired mode, and the industrial personal computer is provided with a signal conditioning circuit and a PCI acquisition card, and the sensor data is conditioned by the signal conditioning circuit and then is sent to the PCI acquisition card. The detection system needs a huge computer to display the monitoring result, and uses a cable to transmit the data acquired by the sensor, so that the detection system is inflexible to use and cannot meet the requirement of a customer for rapidly measuring the vibration of a plurality of crystallizers.

The utility model patent with publication number of CN202903324U discloses a portable crystallizer vibration detector. The detector consists of two triaxial acceleration sensors and a handheld device which is responsible for analyzing, processing and displaying acquired data. The triaxial acceleration sensor is provided with a magnetic base, and sensor data are transmitted to the handheld device in a wired mode. The handheld device comprises various signal conditioning, filtering and analyzing modules, an ARM processor, a storage card, a hydraulic display screen, and indication lamps for working, undervoltage, charging and the like. Although the method reduces the volume of the detector and is convenient to carry, the method still has the defect of complicated wiring.
