Abstract

The invention discloses an off-line detection method for a thermocouple of a continuous casting crystallizer. According to the method, a long-edge copper plate and a short-edge copper plate of the continuous casting crystallizer are arranged on a table top of a temperature rise experiment table, and the plating surfaces face upwards; industrial electric blankets cover the surfaces of the long-edge copper plates and the short-edge copper plates, the thermocouples are connected with thermometers, the industrial electric blankets are connected with an electrical control cabinet, and the electrical control cabinet is provided with heating thermometers of the industrial electric blankets; switching on a power supply to enable the industrial electric blanket to perform temperature rise heating test on the thermocouples of the long-edge copper plate and the short-edge copper plate; when the heating temperature reaches more than 90 DEG C, the reading of the heating temperature meter of the industrial electric blanket is compared with the reading of the thermometer connected with the thermocouple, if the difference value is less than 5 DEG C, the thermocouple is installed perfectly, otherwise, the thermocouple needs to be checked or reinstalled. According to the method, off-line temperature rise test detection of the thermocouple is achieved, operation is convenient, the off-line detection efficiency and the temperature rise test precision are effectively improved, detection energy consumption is reduced, and potential safety hazards are eradicated.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to an offline detection method of a continuous casting mold thermocouple. Background technique [0002] The mold for slab continuous casting machine includes long-side copper plate and short-side copper plate. A thermocouple is installed on the back of the copper plate to detect the real-time temperature of the copper plate, and the temperature signal is transmitted to the control cabinet and converted into a temperature value to be displayed on the display of the industrial computer. , for the production control personnel to monitor the process state of the liquid molten steel forming the billet shell inside the mold in real time. In actual production, the slab continuous caster often has abnormal temperature, which leads to steel breakout accidents, and the breakout detection device is widely used in modern continuous casting machines. Thermocouples may have defects in new prod...
