Rapid testing device of readiness of thermocouples of crystallizer of continuous casting machine

Abstract

The invention relates to a rapid testing device of readiness of thermocouples of a crystallizer of a continuous casting machine, a bus cable is utilized for sending all thermocouple signals on a copper plate of the crystallizer to a PLC signal acquisition module, the PLC is used for converting the thermocouple signals of all channels into the form of real number values and analyzing analog signals acquired by each channel and sending diagnosis information to a monitoring computer with the OPC technology, the computer is utilized for utilizing the visual graphic technology to display all thermocouple data on a monitor screen in the form of a histogram and the values and displaying the diagnosis information of the thermocouples with problems in the form of alarm information, and the database technology is utilized for filing all the acquired thermocouple data, thereby being capable of playing back the filed historical data, and leading a monitoring program to have the functions of producing statements, outputting and printing. The rapid testing device can directly display the values of all the thermocouples, carry out timely treatment on the thermocouples with the problems according to the diagnosis information and improve the efficiency of the readiness process step of the crystallizer of the slab continuous casting machine.

Description

technical field [0001] The invention relates to a rapid test device for thermocouple preparation of a continuous casting machine crystallizer. Background technique [0002] The crystallizer is an important equipment of the slab continuous casting machine in the steelmaking plant of a metallurgical enterprise. The molten steel solidifies after entering the crystallizer, and then forms a billet shell. After forming, the continuous casting billet is pulled out of the crystallizer. It plays a vital role and directly determines the surface and internal quality of the continuous casting slab. Each continuous casting machine must be equipped with a different number of crystallizers. After the mold copper plate reaches the service life, a new mold is replaced to meet the requirements of the continuous casting machine. Continuity of production. [0003] Before and after the crystallizer is put into use, its components must be reassembled. Two rows of thermocouples are installed on t...
